Here’s What The Horns Sounding on a Cruise Ship Mean

You’re on your cruise ship. The entire week is ahead of you. You’re excited about the exotic ports of call, the food, the shows… and yes, the time off from email and the cell phone. You have a drink in your hand. You’re in paradise.

And then… HOOOOOOOOOOOOONNNNNNNNKKKKKK. HOOOOOOOOOONNNNNNKKKKKK.

The ship’s horn sounds loudly. It’s enough to scare you half to death.

While the horns on a cruise ship may surprise you, they are an extremely important aspect of sailing. The ship’s horns harken back to a day before radios and loudspeakers.

They serve as communication with other boats in the area, telling them what the cruise ship is planning to do. Without the horn signals, the risk of a collision would be much greater.

So what do they mean?

As you would guess, different horns have different meanings. We’ve broken down the horn signals with what they mean below.

Inland Waters (Near Port)

One short blast = Changing course to starboard (right) Two short blasts = Changing course to port (left) Three short blasts = Operating in reverse Five short blasts = Danger signal Two long blasts = Leaving berth

Open International Waters

One short blast = Passing on ship’s port side Two short blasts = Passing on ship’s starboard side Three short blasts = Operating in reverse Five short blasts = Danger signal

In addition, ships will also sound their horns for other reasons; most notably in low visibility. This will usually involved regular bursts of sound to let other ships in the area know that the cruise ship is there.

And when a cruise ship makes the sound heard below? Well, that’s just them blowing off a little steam and having some fun.

After one prolonged blast, the boater alerts nearby vessels that it is leaving the slip or dock.

A general emergency alarm is indicated by these seven short and one long blasts of the ship’s horn. The crew may have to leave the ship due to an onboard fire, a grounding, a collision, or other circumstances. In some cases, the crew can hear the ship’s bells or whistles.

It’s 5:59 am and ships are coming in to port when all of a sudden we hear 5 blast????

Danger I do not understand your intentions

Would you happen to know what one VERY long blast means?

I just heard a cruise ship give seven short blast and one long blast… it is at the dock and is departing. Any ideas what this might mean? I have never heard this before, and I live right near the cruise ship terminal.

That’s the emergency signal that’s given during the safety muster drill.

Cool! Thank you!

Did the 1920’s transatlantic passenger ships, prior to leaving, have a signal ‘to get on board.’

I’m not sure.

What Do Cruise Ship Horn Signal Blasts Mean?

Understanding what cruise ship signal horns mean

One of the first things you'll notice when cruising is that cruise ships have a VERY loud horn that while it could be used like your car's horn - actually has a more sophisticated use. While you might just blast your car's horn at a driver that cuts you off, or tap it to let someone know they can go, cruise ships have an internationally recognized set of horn signals that lets everyone around them know exactly what's going on.

When Were The Cruise Ship Horn Signals Established?

In fact, signal horns aren't isn't just for cruise ships. They were codified in the International Regulations for Preventing Collisions at Sea in 1972 and apply to all maritime vessels. In the United States, a similar act was passed in 1980 called the Inland Navigation Rules Act and is a federal statute approved by Congress. However, they were based on earlier conventions and maritime law as practices by the United States and England starting in the mid-19th century. I'm not going to get into more detail about the legal details of these rules regulating horn signals since there are so many vessels out there. Suffice to say, every modern cruise ship adheres to the same simple regulations around signals, regardless of whether they are cruising to Mexico, Canada, or California along the west coast, or an expedition to Antarctica.

What Do Cruise Ship Horn Signals Mean?

There are six different signal horn blast patterns that you will hear on a cruise ship, though the sixth one I hope you will never hear!

One Short Blast - This signal means that your cruise ship intends to pass on it's port side. In inland waters near the port or harbor, this also indicates the cruise ship is changing course to starboard.

One Long Blast - This signal lasting 4-6 seconds means that your ship is leaving the dock. It is a notice to all others around it to be aware that the ship is moving.

Two Short Blasts - Similar to One Short Blast meaning that your ship is passing on the port side, two short blasts means your ship will be passing another on it's starbord side. When in inland waters, this signal horn also means that the ship is changing course to port.

Three Short Blasts - This signal blast means that the ship is backing away from the dock.

One Long Blast Followed by Three Short Blasts - This is actually a combination of two signals horn blasts, letting those around you know that your cruise ship is underway and backing away from the dock.

Five Short Blasts - DANGER! This is a horn signal that you hope to never hear when on a cruise. Regardless of which vessel you are on, this is never a signal blast pattern that you want to hear. Unfortunately, cruise ships are massive vessels and navigation at sea is often an imprecise practice that puts even the best pilot and captain at the mercy of strong and unpredictable winds and currents.

There's also one more signal that very few people will ever hear outside of a drill ...

Seven Short Horn Blasts followed by One Long Blast -  This horn signal indicates a general emergency and will also be accompanied by alarms and visual indicators depending on the ship you are sailing on. 

Cruise Ship Horns Can Be Just For Fun Too!

While cruise ships carry powerful signal horns to ensure safety and communicate with other vessels and structures around them in the harbor, sometimes the horns are used for fun too. No cruise line does this more frequently and with as great sophistication as Disney Cruise Line, though it is not uncommon to hear music produced by the horns on MSC and Cunard ships too.

So now you know what cruise ship horn signals mean and when to expect them. Be careful though if you are on the upper decks during sailaway since forward viewing areas on the upper decks of some ships can be uncomfortablly close to the signal horns. If that's where you find yourself, be prepared to cover your ears!

How to Understand Ship Sound Signals: A Clear Guide for Beginners

Understanding ship sound signals is essential for anyone who spends time on the water. Sound signals are used to communicate between ships, to indicate a vessel’s position, and to warn of potential danger.

Knowing what different signals mean and how to respond to them can help prevent accidents and ensure safe navigation.

Ship sound signals are governed by international regulations set out by the International Maritime Organization (IMO) . These regulations specify the types of signals that ships must use in different situations, as well as the duration and frequency of each signal.

It is important for all boat operators to be familiar with these regulations and to know how to use sound signals correctly.

In this article, we will provide an overview of the most common ship sound signals and explain what they mean. We will also discuss the situations in which each signal should be used and how to respond to them. By the end of this article, readers will have a better understanding of ship sound signals and be better equipped to navigate safely on the water .

How to Understand Ship Sound Signals

Understanding Ship Sound Signals

Ship sound signals are an essential part of navigation, and it’s important to understand them to ensure safe navigation. The International Regulations for Preventing Collisions at Sea (COLREGS) provides guidelines for the use of sound signals, which all ships must follow.

The sound signals used by ships include short blasts, prolonged blasts, and whistle signals. A short blast is a blast of about one second, while a prolonged blast is a blast of four to six seconds. Ships use different types of sound signals, including whistles, horns, and gongs.

The following table provides a summary of the different sound signals used by ships:

It’s important to note that ships may use additional sound signals to communicate with other vessels in specific situations. For example, a ship may use a prolonged blast to indicate its position when it is at anchor.

In addition to the sound signals themselves, it’s important to understand the context in which they are used. For example, a ship may use a short blast to indicate a course change, but it’s important to understand the direction of the course change to avoid a collision.

In conclusion, understanding ship sound signals is essential for safe navigation. By following the guidelines set forth in the COLREGS and paying attention to the context in which sound signals are used, ships can communicate effectively and avoid collisions.

Types of Vessels and Their Signals

When it comes to understanding ship sound signals, it’s important to know the different types of vessels and their respective signals. Here are the signals for various types of vessels:

Signals for Power-Driven Vessels

Power-driven vessels are those propelled by machinery. They include ships, motorboats, and other vessels that are not sailing vessels. The following are the signals for power-driven vessels:

  • One short blast: means “I am altering my course to starboard.”
  • Two short blasts: means “I am altering my course to port.”
  • Three short blasts: means “I am operating astern propulsion.”

Signals for Sailing Vessels

Sailing vessels are those that are under sail and not using machinery. The following are the signals for sailing vessels:

  • One long blast followed by two short blasts: means “I am sailing and have restricted maneuverability.”
  • Two long blasts: means “I am unable to maneuver.”

Signals for Vessels Not Under Command

Vessels not under command are those that are unable to maneuver due to exceptional circumstances, such as engine failure. The following are the signals for vessels not under command:

  • Two long blasts followed by two short blasts: means “I am not under command.”

Signals for Vessels Engaged in Fishing

Vessels engaged in fishing are those that are fishing with nets, lines, or trawls. The following are the signals for vessels engaged in fishing:

  • One long blast followed by two short blasts: means “I am fishing and have restricted maneuverability.”

Signals for Vessels at Anchor

Vessels at anchor are those that are anchored in a fixed position. The following are the signals for vessels at anchor:

  • One short blast: means “I am anchored.”

Signals for Towing Vessels

Towing vessels are those that are towing other vessels or objects. The following are the signals for towing vessels:

  • One long blast followed by one short blast: means “I am towing astern.”
  • Two long blasts followed by one short blast: means “I am towing alongside.”
  • Three long blasts followed by one short blast: means “I am pushing ahead.”

Understanding the different types of vessels and their signals is crucial for safe navigation at sea.

Navigational Rules and Sound Signals

Inland rules.

The Inland Rules are a set of regulations that apply to vessels operating on the inland waters of the United States. These rules are based on the International Regulations for Preventing Collisions at Sea (COLREGS) but have been modified to suit the specific needs of inland waterways.

The Inland Rules specify the sound signals that vessels should use to communicate their intentions to other vessels. For example, a vessel that is underway but not making way should sound one prolonged blast every two minutes. A vessel that is approaching a bend in a narrow channel should sound one prolonged blast followed by two short blasts.

International Rules

The International Rules, also known as the COLREGS, apply to vessels operating on the high seas and in international waters. These rules have been adopted by most maritime nations and are designed to prevent collisions at sea.

The International Rules specify the sound signals that vessels should use to communicate their intentions to other vessels. For example, a vessel that is underway but not making way should sound one prolonged blast every two minutes. A vessel that is approaching another vessel head-on should sound one short blast to indicate that it intends to pass on the starboard side.

Both the Inland Rules and the International Rules are designed to ensure the safety of vessels operating on the water. It is important for all mariners to be familiar with these rules and to use sound signals appropriately to avoid collisions.

Significance of Visibility in Sound Signals

Visibility is a critical factor in understanding ship sound signals. In restricted visibility, such as fog, it is challenging to identify the location and direction of sound signals. Therefore, it is essential to take precautions and sound the appropriate signals to avoid collisions.

The International Regulations for Preventing Collisions at Sea (COLREGs) state that sound signals must be used to indicate the vessel’s position, direction, and intention. The signals must be audible at a distance of at least one mile and must not be confused with any other signal.

In restricted visibility, vessels must use the appropriate sound signals to indicate their presence and direction. For example, a vessel underway but stopped and making no way through the water must sound one prolonged blast at intervals of not more than two minutes. A vessel making way through the water must sound one prolonged blast followed by two short blasts at intervals of not more than two minutes.

The significance of visibility in sound signals is that it allows vessels to identify the location and direction of other vessels. In restricted visibility, it is challenging to see other vessels, and sound signals become the primary means of communication. Therefore, it is crucial to maintain a proper lookout and sound the appropriate signals to avoid collisions.

In areas of restricted visibility, such as fog, vessels must reduce speed to a safe speed and navigate with caution. The COLREGs state that vessels must proceed at a safe speed , taking into account visibility, traffic density, and the vessel’s maneuverability. It is essential to sound the appropriate signals to indicate the vessel’s presence and direction and avoid collisions.

In conclusion, visibility is a critical factor in understanding ship sound signals. In restricted visibility, vessels must use the appropriate sound signals to indicate their presence and direction and avoid collisions. It is essential to maintain a proper lookout and navigate with caution in areas of restricted visibility.

Maneuvering and Warning Signals

When navigating in open waters, ships use sound signals to communicate with each other. These signals are essential for ensuring safe navigation and avoiding collisions. Understanding the different types of sound signals is crucial for any ship’s crew.

Maneuvering Signals

Maneuvering signals are used to indicate a ship’s intention to maneuver. These signals can be used to indicate a ship’s intention to turn, stop, or change speed. The following are some of the most common maneuvering signals:

  • One short blast: This signal indicates that the ship is altering its course to starboard (right).
  • Two short blasts: This signal indicates that the ship is altering its course to port (left).
  • Three short blasts: This signal indicates that the ship is operating astern propulsion.

Warning Signals

Warning signals are used to alert other ships of a ship’s presence or intention. These signals are essential for avoiding collisions. The following are some of the most common warning signals:

  • One prolonged blast: This signal indicates that the ship is underway and is approaching another vessel. It is used in situations where there is a risk of collision.
  • Two prolonged blasts: This signal indicates that the ship is being towed.
  • Three prolonged blasts: This signal indicates that the ship is not under command and cannot maneuver.

Safe Passing

When two ships are passing each other, they use sound signals to indicate their intentions. The following are some of the most common safe passing signals:

  • One short blast followed by one prolonged blast: This signal indicates that the ship is overtaking another vessel on its starboard side.
  • Two short blasts followed by one prolonged blast: This signal indicates that the ship is overtaking another vessel on its port side.
  • One prolonged blast followed by two short blasts: This signal indicates that the ship is in doubt about the other vessel’s intentions.

In conclusion, understanding ship sound signals is crucial for safe navigation in open waters. By knowing the different types of signals and their meanings, ship crews can communicate effectively with each other and avoid collisions.

Ship Light Signals and Equipment

Types of lights.

Ships use various types of lights to signal their position, direction, and intentions. The following are the most common lights used on ships:

  • Masthead light : A white light placed on the ship’s bow, the forward part of a ship that is visible from ahead to 22.5 degrees abaft the beam on either side of the ship.
  • Sidelights : Red and green lights that are placed on the port and starboard sides of a ship , respectively. They are visible from ahead to 22.5 degrees abaft the beam on their respective sides.
  • Sternlight : A white light placed at the stern of a ship that is visible from astern to 22.5 degrees on either side of the ship.
  • All-round light : A white light that is visible from all directions.
  • Towing light : A yellow light that is used to indicate that a ship is towing another vessel.

Legal Requirements for Lights

The International Regulations for Preventing Collisions at Sea (COLREGS) specify the legal requirements for lights on ships. The following are the most important requirements:

  • Ships must exhibit the appropriate lights depending on their size, type, and activity.
  • Masthead lights must be visible from a distance of at least 6 nautical miles, sidelights from at least 3 nautical miles, and sternlights from at least 2 nautical miles.
  • Ships must exhibit a white light that can be seen from a distance of at least 2 nautical miles in all directions when anchored.
  • Towing vessels must exhibit the appropriate lights depending on the length of the tow and the type of vessel being towed.

It is important for all ship operators to understand the legal requirements for lights and to ensure that their vessels are properly equipped and maintained. Failure to comply with these regulations can result in fines, legal liability, and even accidents at sea.

Communication and Sound Signals

Communication is essential in ensuring the safety of vessels at sea. The International Regulations for Preventing Collisions at Sea (COLREGs) require ships to use sound signals to communicate with each other in various situations. Understanding these signals is crucial for all seafarers.

The use of radiotelephone communication has become increasingly popular in recent years. The Bridge-to-Bridge Radiotelephone Act requires all vessels to maintain a watch on the appropriate frequency and to communicate with other vessels when necessary. This act ensures that ships can communicate with each other in real-time, enabling them to avoid collisions and other hazards.

In addition to radiotelephone communication, ships use sound signals to communicate with each other. Sound signals are used to indicate a ship’s presence, its intentions, and its movements. The COLREGs specify the different types of sound signals that ships should use in various situations.

For example, a vessel should sound one short blast to indicate its intention to overtake another vessel on its port side. Conversely, a vessel intending to overtake on its starboard side should sound two short blasts. A vessel should sound five or more short blasts to indicate danger or to signal that it is confused about the intentions of another vessel.

It is important to note that the use of sound signals does not replace the need for visual communication. Ships should always maintain a visual lookout and use sound signals as a supplement to visual communication.

Overall, understanding sound signals is critical for safe navigation at sea. Seafarers should familiarize themselves with the COLREGs and the Bridge-to-Bridge Radiotelephone Act to ensure that they can communicate effectively with other vessels.

Safety and Emergency Signals

Ship sound signals are important for ensuring the safety of ships and their crew. In emergency situations, sound signals can be used to alert other ships of danger and to communicate a need for assistance. The following signals are used in safety and emergency situations:

  • One prolonged blast : This signal is used to indicate the ship’s position in foggy conditions. It should be sounded every two minutes.
  • One short blast : This signal is used to indicate that a ship is altering its course to starboard (right). It should be sounded before the turn is made.
  • Two short blasts : This signal is used to indicate that a ship is altering its course to port (left). It should be sounded before the turn is made.
  • Five short blasts : This signal is used to indicate danger or to signal that immediate action is required.
  • One prolonged blast followed by two short blasts : This signal is used to signal an emergency situation.

It is important for all ships to have a lookout on duty at all times, especially in congested areas or in poor visibility. The lookout should be aware of the ship’s sound signals and be able to recognize them when they are heard.

In emergency situations, it is important to communicate clearly and quickly. Ships should use all available means of communication, including radio and visual signals, in addition to sound signals. The crew should also be trained in emergency procedures and drills to ensure that they can respond quickly and effectively in an emergency situation.

Understanding Ship Positions and Their Signals

When it comes to understanding ship sound signals, it’s important to first have a basic understanding of ship positions and their signals. This can help you recognize what a ship is trying to communicate and respond appropriately.

Port Side and Starboard Side

Ships have two sides: port and starboard. Port is the left side of the ship when facing forward, and starboard is the right side. When a ship sounds a signal of one short blast, it means that the ship is altering its course to starboard. Two short blasts indicate a course alteration to port.

Astern Propulsion

If a ship is moving in reverse, it will sound a long, steady blast. This signal tells other vessels to keep clear because the ship is not able to maneuver as easily as it would when moving forward.

When a ship is approaching a berth, it will sound a long, prolonged blast. This signal is meant to warn other vessels that the ship is about to dock and may require extra room to maneuver.

Vessel Aground

If a ship runs aground, it will sound three short blasts followed by one long blast. This signal is meant to alert other vessels of the danger and to request assistance if necessary.

In summary, understanding ship positions and their signals is essential for safe navigation on the water. By knowing what each signal means, you can avoid collisions and respond appropriately to other vessels.

Speed and Distance in Relation to Sound Signals

When it comes to understanding ship sound signals, it’s important to consider the speed and distance of the vessels involved. In general, the faster a ship is moving, the shorter the sound signal will be in duration. This is because the sound waves have less time to travel before the ship has moved a significant distance.

For example, if a ship is traveling at a speed of 15 knots , its sound signal will typically be around 2 seconds long when sounded in open waters. However, if the ship is traveling at a slower speed of 5 knots, the sound signal will be longer, typically around 5 seconds.

In addition to speed, distance is also a key factor to consider when it comes to sound signals. The International Regulations for Preventing Collisions at Sea (COLREGS) require vessels to sound specific signals when they are in certain situations or approaching other vessels. These signals vary depending on the distance between the vessels.

For example, when a vessel is within half a mile of another vessel, it must sound a signal consisting of one short blast followed by one long blast. When the vessels are within a quarter of a mile of each other, the signal changes to two short blasts followed by one long blast.

It’s important to note that these signals are standardized and must be used by all vessels in the appropriate situations. By understanding the relationship between speed, distance, and sound signals, mariners can communicate effectively and avoid collisions at sea.

Seamanship and Sound Signals

Seamanship is the art of safely navigating a vessel through the water. One important aspect of seamanship is understanding and properly using sound signals. Sound signals are used to communicate with other vessels and indicate the vessel’s intentions.

The ability to maneuver a vessel is crucial in avoiding collisions and navigating through narrow channels. Sound signals can be used to communicate a vessel’s maneuvering intentions, such as turning to port or starboard.

When navigating through a fairway, sound signals can be used to indicate the vessel’s position and intentions. For example, a vessel approaching a bend in the fairway may sound one long blast to indicate its presence and intention to navigate around the bend.

Shapes are also used to indicate a vessel’s intentions and status. For example, a vessel at anchor will display a black ball shape, while a vessel restricted in its ability to maneuver will display a red and white diamond shape.

Pushing or towing a vessel requires additional sound signals to indicate the vessel’s intentions and movements. For example, a vessel pushing ahead will sound one short blast to indicate its intention to move forward.

In summary, understanding and properly using sound signals is an important aspect of seamanship and safe navigation. By communicating effectively with other vessels and indicating intentions, collisions and other dangerous situations can be avoided.

Cruise ships have specific communication protocols to convey different types of emergency situations. The ship’s horn is used to warn passengers of imminent danger, such as a fire or a collision with another vessel. The signal for this emergency is seven short blasts followed by one long blast. This signal means that all passengers should assemble at their designated muster stations for evacuation procedures.

In addition to the emergency signal, cruise ships also use the horn to communicate other important safety information. For example, the signal for a man overboard is three long blasts, which means the crew should immediately begin search and rescue operations.

It’s important for passengers to pay attention to these signals and follow all safety instructions provided by the crew in order to ensure a safe and enjoyable cruise experience.

Horn Battles and Fun Activities

It’s always amusing to witness two massive vessels engaging in a musical competition on the open sea, don’t you think? Horn battles have become increasingly popular among cruise lines as a way to create a fun and friendly atmosphere onboard.

However, there is a certain etiquette that needs to be followed to ensure that the competition remains safe and enjoyable for everyone involved.

First and foremost, horn battles should only be done in open waters and away from other vessels. Cruise ships are massive and powerful, so it’s important to ensure that they don’t accidentally collide with each other or cause any harm to nearby ships.

Additionally, the battle should be brief and not disturb other passengers who may be trying to relax or sleep.

Despite these guidelines, horn battles have become a beloved tradition among cruise enthusiasts, with Disney Cruise Line leading the pack with their impressive musical horns and elaborate battles.

What is the history of cruise ship horns and how have they evolved over time?

The evolution of cruise ship horns can be traced back to their role in navigation and warning signals. With advancements in sound engineering and acoustics, cruise ship horns are now designed to be heard from a distance of two nautical miles, while also adding a tunefulness to the travel experience.

How do cruise ships ensure that their horns are audible from two nautical miles away in foggy conditions?

To ensure that cruise ship horns are audible from two nautical miles away in foggy conditions, technological advancements in sound engineering have been implemented. These advancements enable the horns to produce a loud and clear sound that can easily be heard, promoting safety at sea.

Can passengers request to participate in a horn battle between their ship and another ship?

Passengers cannot request to participate in a horn battle as it violates regulations and etiquette. Horn battles have a history of being fun, but safety is a priority. Exploring cruise ship horns is fascinating, but professional and technical.

What is the protocol for using the horn in case of a medical emergency onboard the ship?

In case of a medical emergency onboard the ship, the notification protocol is activated immediately. The horn usage is one of the onboard procedures used to signal for emergency response, ensuring passenger safety.

Are there any regulations or restrictions on the use of cruise ship horns in certain parts of the world or during certain times of day?

Did you know that regulations and time restrictions on cruise ship horns vary by location? In some areas, such as Alaska, there are strict noise pollution regulations, while in others, there are time restrictions to limit the environmental impact.

Ship Horn Signals and Their Meanings

Written by Anthony Roberts / Fact checked by Jonathan Larson

ship horn signals

Large and small vessels honking at the harbor and elsewhere are fascinating to watch and hear, but do we understand what these ship horn signals mean?

Sailors say one prolonged blast every two minutes signals a watercraft’s presence in hazy, cloudy, foggy, or other low-visibility situations.

One prolonged and two short blasts at two-minute intervals also indicate poor visibility for fishing boats, sailing vessels, and towing watercraft. These boat sound signals can also mean the absence of a commanding officer onboard, draft issues, or maneuverability concerns.

Learning the different sound signals for boats and ships helps boost boating safety by improving ship communication methods. It conveys one boater’s presence or intended action to others without “talking” to them.

2. combinations of short and long blasts, 3. horn signals for each situation, 4. maneuvering, warning, and limited visibility signals, 1. based on vessel length, 2. when do i make sound.

Watercraft operators must know how to interpret ship horn signals across situations. Nautical horn signals use short blasts lasting a second or 4- to 6-second prolonged blasts or a combination of both. Let’s look at these sound signals and appreciate their meanings.

sound-signals-for-boats

Among many marine signals you must know as a boater, let’s start with the basic navigational sound codes using short and long blasts.

The following marine sound signals chart combines prolonged and short horn blasts.

interpret-ship-horn-signals

Vessels must sound their horns using the correct ship horn codes only when they are within visual range of each other. Other conditions include a half-mile distance between the ships, and they are on course to crossing or meeting head-on.

Vessel operators must only use these sound signals in clear weather (i.e., not foggy nor hazy) for horn signals to be valid. In situations of poor visibility, ships must sound fog signals instead.

You might hear 3 long blasts, especially on cruise ships. Sailors disregard these sounds because they don’t mean anything. They are only for “show,” just as 5 long blasts on ships horn don’t exist in the rules.

nautical-horn-signals

We already covered some ship horn rules related to maneuvering, warning, and limited visibility. The following sound signal patterns expand our understanding of boat sound signaling protocols. These codes will help you interpret Great Lakes freighter horn signals or any vessel.

Requirements and Regulations on Ship Horn Signals

Here are other sound-signaling rules all boaters must know.

Based-on-Vessel-Length

Watercraft shorter than 39.4 feet must have one sound-signaling device (i.e., air horn, whistle, or bell) to draw attention from other boaters in an emergency.

Boats between 39.4 and 65.6 feet must have two sound-signaling devices (i.e., a whistle and a bell). The whistle must produce a sound audible within half a nautical mile. Meanwhile, the bell must have a mouth diameter of not less than 7.87 inches.

As mentioned, vessel operators should only make a sound with their horns or other sound-signaling devices when they are within the visual range of another boat (within half a mile). Moreover, basic horn signals only apply on clear days. Fog horn signals are necessary for low visibility conditions.

Mastering different ship horn signals is a crucial skill for vessel operators.

These non-verbal communication signs allow boaters to maneuver their watercraft safely while warning other vessels of their movements or ship status. Some horn signals are perfect for alerting other boaters of one’s presence in low-visibility situations.

It’s worth noting that some horn signals are uncommon, while a few don’t have meaning. Hence, boaters must distinguish legitimate sound signals from unsanctioned ones to ensure clear communication among boaters.

Cruise ship horns and what they mean

Ever wondered what two short blasts of the horn mean when you hear them along the River Mersey?

  • 05:00, 2 JUL 2022

The River Mersey is a busy shipping lane with a huge variety of vessels arriving every week.

Keen ship spotters always love it when a cruise ship sails in and, following the pandemic, it was one of the first signs of the tourism industry coming back into the city. Liverpool has already welcomed dozens of ships this year, with many more on the horizon.

Last year, a total of 90 cruise ships on round-Britain tours visited the port and people living along the river will be well accustomed to hearing the horns of the floating hotels ringing out over the Mersey . But some may not know the number of bursts and their length of the horn blasts means different things.

We have looked at what some of the different horns mean so next time you hear them sound, you will know if the ship is arriving, leaving or if it is in trouble and needs help. These all refer to inland waters as in open waters, in some cases, they refer to something slightly different.

One short blast - means the ship is changing course to starboard (to the right). In open waters this means a ship passing on the ship's starboard side.

Two short blast - means the ship is changing course to port (to the left) In open waters this means a ship passing on the ship's port side.

Three short blasts - means the ship is operating in reverse. This means the same in open waters.

Five short blasts - this is the ship's danger signal in both inland and open waters.

Two long blasts - this means the ship is leaving berth.

Visitors from passing cruise ships are estimated to bring in between £13m and £15m each year to the local tourism economy.

Speaking recently to the ECHO about the cruise ships coming back to Liverpool after the restrictions of the pandemic, John Mawer who is the Head of Cruise Operations at Liverpool Council , said: "This is our first full season and it's good to see the cruise terminal back in action again and operating to nearly its full capacity. Even last year, we managed to bring in 90 cruise ships when domestic travel was re-introduced as part of the road map for emerging from the pandemic.

"Cruises were included in that thanks to lobbying from the industry. This was only a slight drop from the 105 cruise operators we had pre-pandemic. Under the road map, only round-Britain trips were allowed for vaccinated passengers. In other words, this meant the destination was the ship, which was like a floating hotel. It fell under domestic travel guidance, and was open to UK citizens in UK territorial waters."

He added: "It does feel like we're back to some normality. In one week, we had 10,000 visitors from a range of different ships. The feedback's been great. The minute passengers step off the gangway, they get that famous Scouse welcome."

Cruise Ship Horn – The History and Significance

Cruise ship horns have a particularly distinct sound that is very, very loud. However, you shouldn’t mistake a cruise ship’s horn for the same purpose as your car’s horn, for example. 

They are an essential part of water navigation and are crucial for the safety of the ship and other ships at sea. They have a unique significance, and different blasts mean different things. 

Keep reading to learn the history and significance of a cruise ship horn, and discover the meaning of the different blasts you may hear throughout your cruise.

In This Article…

Cruise ship horn history and purpose.

As maritime vessels, cruise ships subscribe to the International Regulations for Preventing Collisions at Sea and other standard regulations.

Standardized international regulations were established to codify important vessel operation procedures. Part of this standardization includes having adequate horns on large vessels, and cruise ships are no exception.

Cruise Ship Horns

These regulations are essential to ensure good communication between all vessels for the safety of all those onboard. The main point of a cruise ship horn is to avoid a collision at all costs. 

Cruise Ship Horn – Why Do They Blast Their Horns?

There are various reasons why cruise ships blast their horns, ranging from a simple salutation to other passing ships to a warning of potential danger or an emergency.

For the most part, however, most horn blasts are to communicate with other passing ships what direction the ship plans on going. This is done using various horn signals that all vessels understand.

Why Are Ship Horns So Loud?

You’re on your cruise deck relaxing and trying to get a tan when suddenly you hear the loud blaring of the horn. While this may startle you and even be annoying, there’s an important reason that cruise ship horns are so loud. 

Cruise ship horns are so loud because of how big the open sea is. They act as a warning to other boats and vessels at sea. They need to be heard in cases of low visibility and in cases of emergency.

Docked Cruise Ships

In general, you can hear cruise ship horns from up to two miles away. Cruise ships are pretty slow to stop and turn due to their enormous size, so this much space is needed as a warning to get out of another ship’s way. 

Ship Horn Blasts – What Do They Mean

You may have noticed that cruise ships have several different blasts. But what do they mean? Here’s a quick look into what the horn blasts mean.

  • One short horn blast: This communicates to another ship that you intend to pass it on your port side. 
  • Two short horn blasts: This communicates to another ship that you intend to pass on your starboard side .
  • Three short horn blasts: This means that you are operating in reverse, such as backing away from the dock.
  • One prolonged horn blast: This is the first blast you’ll often hear onboard your cruise, as the blast signals that a vessel is leaving the dock.
  • Five short horn blasts: This typically signals danger and is the type of blast you are least likely to hear on your ship

Aside from these reasons, your ship might also sound its horn in times of low visibility just to make its presence known.

Although cruise ship horns tend to startle and scare people onboard the ship, there’s rarely anything to worry about. In general, the ship’s captain blasts the horn signal only to communicate.

what do cruise ship horn blasts mean

Why Do Boats Blow Their Horn? (8 Signals Explained)

' src=

Both commercial and recreational watercraft use horns and sound signals to indicate their intentions to other boaters.

Sound signals are used in place of other signals that you might see in other vehicles, such as turn signal lights or other visual indications.

Utilizing the proper sound signals is a part of the navigational rules that all boaters need to know.

If you are going to operate a boat, you should learn how to properly utilize and understand boating horn signals:

Table of Contents

what do cruise ship horn blasts mean

8 Sound Signals Everyone Should Know

Have you ever been boating recreationally, and another ship honks its horn at you?

This might at first seem like a friendly greeting, but it most likely means that the other vessel is trying to communicate to you and tell you something.

When navigating in the water, especially in crowded conditions, using your sound signals can announce your intentions to other boaters.

3 Sound Signals that Indicate Direction:

  • A Short Blast This horn signal indicates the plan to pass on your port side (this requires a turn to the right).
  • Two Short Blasts This horn signal indicates the plan to pass on your starboard side (this requires a turn to the left).
  • Three Short Blasts This signal indicates that you are backing up.

2 Sound Signals that Indicate Location:

  • You can combine 1 long blast followed by 3 short blasts to indicated backing out of your dock or slip.
  • You can also use 1 long blast in intervals less than two minutes to indicate in blind areas or fog that you are a power vessel.
  • One Long Blast and Two Short Blasts This boat signal indicated in blind areas or fog that your vessel is a sailing vessel.  It should be repeated every two minutes.

2 Sound Signals to Use in the Channel

  • One Long Blast and One Short Blast This signal indicates you plan to overtake the boat ahead of you on your port side (this requires a turn to the right).
  • One Long Blast and 2 Short Blasts This signal indicates that you plan to overtake the boat ahead of you on your starboard side (this requires a turn to the left).

A Sound Signal that Indicates Danger

5 Short Blasts This horn signal indicates danger and can be used to communicate potential collision with another vessel.

It can also be used while approaching an oncoming vessel that you do not understand their intentions or are otherwise confused by their actions.

In a channel where travel is often faster, communication is even more important. The channel’s signals follow the system above direction signals that include the preceding long blast warning signal.

Boat Horn Signal Basics

To properly use and understand sound signals, you will need to understand the basics.

Sound signals for boats need to be loud and heard up to a half of a nautical mile away. Sound signals include both short and long blasts:

  • Short blasts would be a sound that lasts 1 second.
  • Long blasts should last between 4-6 seconds so that other boaters can be confident in the difference between your short and long blasts.

Sound signals can be used to communicate a change in direction, pass other boaters, indicate the location, or alert someone to danger.

Sound signals are typically used in conditions with good visibility and are not appropriate in high fog. Only emergency fog signals should be used in scenarios with low visibility.

Port vs. Starboard

One thing that will help any boat operator or a passenger know the difference between port and starboard. To correctly identify to port and starboard side, you will need to be looking towards the boat’s front.

  • The port side is the left side of the boat if you are looking towards the bow.
  • The starboard side is the right side of the boat if you are looking towards the bow.

Knowing the difference between port and starboard is important. This is because they are fixed directions on your boat and never change, while directions like “right” and “left” can change depending on the direction you are facing.

If everyone knows the difference between port and starboard, it can minimize confusion that can be brought on by using “right” and “left.”

Starboard stems from old English words meaning “steer” and “the side of a boat” because most rowers were right-handed.

The Portside was named for the side that faced the port and allowed for boarding.

5 Basic Navigation Rules Everyone Should Know:

Even though boating can be a fun, family-friendly activity, it can also be stressful and intimidating if you don’t know the proper navigation rules.

It can be even more stressful when waterways are crowded and busy.

As a boat operator, it is your job to ensure the safety of you and your passengers and be respectful and cautious of fellow boaters.

Below are some basics you should know that can help you and your passengers enjoy a safe boating experience when paired with the use of sound signals.

Some basic safety tips that everyone should know include:

  • Do not go too fast. Accidents can be prevented by using safe speeds and only going fast when the conditions allow for it, and you have enough space to slow down if needed.
  • Be careful. Not every boater knows the basic navigation rules, so you should not count on everyone following them. If other boaters seem to be exhibiting unsafe behavior, it is best to keep your distance.
  • Be respectful. Other boaters may have some things going on that you cannot see. Make sure when interacting with other vessels, you are respectful of them. If you have the right of way, but it makes sense for them to go, you should give them the right way, especially if this is a safer option.
  • Avoid government crafts and restricted areas. Government vessels should be given the right of way whenever possible, and you should make sure you are giving them the proper space.
  • Know the basic navigation rules and how to determine the right of way.

Some basic navigation and right of way rules include:

When approaching a non-power vessel:

  • When a sailboat is using their sails for power, they have the right of way.
  • If they are using their auxiliary power motor, they should be treated as a powerful vehicle.

When approaching a power vessel:

  • If the boat is approaching from the port side, you have the right of way.
  • If the boat is approaching from the starboard side, they have the right of way.
  • If the boat is approaching from behind, you will have the right of way, even if they are a non-power vessel.
  • If you approach a boat head-on, you should pass each other port side to port side, unless otherwise agreed.

How You Should Respond to Sound Signals

You need to know while utilizing sound signals that a mimicked signal usually signifies agreement.

For example, if another boater uses 1 short blast to indicate that they are passing on their port side, you would respond with your own single short blast to indicate that you understand and agree.

This communication will help you and the other boater know that you both understand what is going on and agree to the indicated maneuver.

If you disagree with the other boater’s proposed maneuver, you can signal this with 5 short blasts. This indicates to them that you do not agree with or understand their proposed maneuver.

The Importance of Safety Sound Signals

You might not think these signals are important to know. Perhaps you have been boating for years without using them. But they are essential.

Most boating accidents are caused by user error and can be avoided with proper knowledge and training.

Over 80% of boating accidents are caused by people who have not had the proper boaters training course. This is because not all states require everyone to have a “boater’s license” or Boater Education Card.

As a result of this lack of proper education and training, many people out on the water never learned how to utilize these signals or the navigation rules properly.

You must know these rules so that you properly execute the right of way and safely navigate around other vessels.

However, despite your proper utilization of navigation rules and proper sound signals, you will still want to be careful and cautious around your fellow boaters. Those who do not know the rules will likely not utilize them.

Never assume that just because you have the right of way or are otherwise properly communicating, other people will understand you or follow the right of way rules.

what do cruise ship horn blasts mean

Marine Horn Signals: A Comprehensive Guide

by Emma Sullivan | Aug 3, 2023 | Sailing Adventures

what do cruise ship horn blasts mean

Short answer marine horn signals:

Marine horn signals are auditory warnings used by ships to communicate important information and ensure safe navigation at sea. They convey messages such as course changes, imminent danger, and identification. These signals are standardized internationally to promote consistent understanding among maritime vessels.

Understanding Marine Horn Signals: A Complete Guide for Seafarers

As seafarers, it is crucial for us to effectively communicate with other vessels while out on the open sea . One of the most common methods of communication at sea is through marine horn signals. These signals, also known as sound signals or soundings, serve as a language that all sailors must understand and adhere to in order to ensure safety and prevent accidents.

So, let’s dive deep into this complete guide on understanding marine horn signals, where we’ll decode the different signals and their meanings.

1. The Short Blast (1-Second Long): If you hear a short blast from another vessel’s horn , it means they are altering their course to starboard (right). Whenever you detect this signal, be prepared to take appropriate action and avoid collision.

2. The Prolonged Blast (4-6 Seconds Long): A prolonged blast of a ship’s horn indicates that they are maneuvering in restricted visibility. This could include situations such as navigating through foggy conditions or heavy rain. When you hear this signal, keep an eye out for that vessel and be cautious as there may be limited visibility ahead.

3. The Short Series of Blasts: A series of short blasts signifies doubt or potential danger between approaching vessels. If you hear another ship give off several rapid short blasts in succession, it means they’re unsure about your intentions and fear a possible collision might occur. In such situations, try to communicate visually or via radio if possible to clarify your intentions and alleviate any concerns.

4. One Prolonged Blast Followed by Two Short Blasts: This specific combination has two different interpretations based on who gives the signal – large commercial ships versus smaller vessels:

– On large commercial ships: The sequence one prolonged blast followed by two short blasts is an indication that the large vessel cannot maneuver easily due to its size or draft restrictions. This signal acts as a warning for smaller boats to maintain a safe distance and avoid crowding around the larger vessel.

– On smaller vessels: In contrast, if you’re on a smaller craft, using this sequence indicates your intention to overtake another vessel from its starboard (right) side.

5. The Prolonged Blast Followed by Several Short Blasts: This particular combination of horn signals is exclusive to pilot vessels assisting with navigation. When a pilot boat emits one prolonged blast followed by several short blasts, it signifies that pilots are coming aboard or leaving different ships. As seafarers, it’s important to respect and comply with the pilot’s instructions during these situations.

Now that we have explored some of the most common marine horn signals, it’s crucial to remember two significant points:

1. Maintain Awareness: Always be vigilant while at sea and pay attention to both audible and visual signals from other vessels. It’s essential to readily identify what each sound means in order to react promptly and safely navigate through any potential encounters.

2. Consistency is Key: When operating your own vessel, make sure you adhere to internationally recognized standards and regulations regarding sound signals . Consistency among seafarers ensures smooth communication at sea and minimizes the risk of confusion or misinterpretation.

In conclusion, understanding marine horn signals is vital knowledge for seafarers worldwide. By familiarizing ourselves with these signals and their meanings, we can enhance safety at sea, prevent accidents, and foster effective communication between vessels. So next time you hear a ship’s horn sounding out its unique language, decode it confidently and sail on!

How to Properly Use Marine Horn Signals: A Step-by-Step Tutorial

Mastering marine horn signals is a crucial skill for every boat owner or operator. Not only do these signals ensure effective communication between vessels, but they also play a vital role in promoting safety and avoiding potential maritime accidents. In this comprehensive step-by-step tutorial, we will guide you through the proper usage of marine horn signals, unraveling their meanings and showcasing their importance.

Step 1: Understand the Signal Categories Before delving into specific horn signals, it is essential to familiarize yourself with the different categories of signals. The International Regulations for Preventing Collisions at Sea (COLREGs) outline three primary categories:

1. Sound Signals: These are audible indications using horns or whistles that boats emit to convey various messages. 2. Light Signals: This category involves signaling by using lights during specific situations like navigation in restricted visibility. 3. Communication Signals: While primarily used for ship-to-ship communication via radio, understanding common communication signals can be useful when coordinating with other vessels.

Step 2: Get Acquainted with Key Horn Signals Next, let’s explore the most commonly used sound signals and their meanings:

1. Short Blast (One Second): This signal indicates intentionality, typically used as a warning before maneuvering in narrow channels or near blind bends. Example Scenario: As you approach a sharp turn on a river where visibility is limited, give one short blast to alert any oncoming traffic about your presence.

2. Prolonged Blast (Four to Six Seconds): Emitting this signal serves as an indication of danger or potentially unsafe situations . Example Scenario: If you spot another boat rapidly approaching head-on towards your vessel and an imminent collision appears likely, immediately release a prolonged blast to alert them of the critical situation.

3. Two Short Blasts (Repeated): This signal signifies altering your course starboard/right side. Example Scenario: When intending to steer your boat towards the starboard side , emit two short blasts every two minutes while maintaining your present heading until other vessels acknowledge and respond accordingly.

4. Three Short Blasts (Repeated): This signal indicates altering your course port/left side. Example Scenario: If you plan to maneuver your vessel towards the port side, consistently emit three short blasts at two-minute intervals while holding your current course until nearby boats acknowledge and adjust their path accordingly.

5. Five (or more) Short Blasts (Repeated): This sound signal conveys doubt or potential confusion regarding another vessel’s intentions. Example Scenario: If you are unsure about another vessel’s actions or if they fail to respond to other sound signals promptly, delivering five short blasts in quick succession can express apprehension and prompt them to clarify their intentions.

Step 3: Additional Considerations While understanding these key horn signals is essential, it is equally important to consider a few additional factors:

1. Distance and Volume: Ensure that the volume of your horn is sufficient for others to hear the alert, taking into account weather conditions, boat size, and surrounding noise. 2. Equipment Maintenance: Regularly inspect and maintain your horn or whistle system, as malfunctioning equipment may result in miscommunication or accidents on the water. 3. Local Regulations: Familiarize yourself with any specific sound signaling rules imposed by local maritime authorities in your region as they can vary slightly from international standards.

By thoroughly comprehending marine horn signals and consistently incorporating them into your boating practices, you contribute significantly to safety and effective communication on the waterways. So sail forth with confidence, knowing that you can navigate any situation with clear auditory finesse!

In conclusion: Effective use of marine horn signals stands as an imperative skill for seafarers of all levels. By following this step-by-step tutorial and embracing comprehensive knowledge about different signal categories and meanings, you will be well-equipped to navigate safely, prevent accidents, and communicate seamlessly with other vessels. Remember, mastering marine horn signals not only elevates your professional prowess but also ensures the safety of all those who share the waters with you.

This blog post aims to shed light on why these seemingly simple horn signals are crucial for maintaining order and safety at sea.

The primary purpose of marine horn signals is to convey essential information between vessels, ensuring safe navigation and preventing potential accidents. These signals act as a universal language that all sailors understand, transcending barriers of spoken languages and enabling effective communication even in adverse conditions.

Navigational Hazards: Averting Disaster One of the critical aspects of marine horn signals is their role in warning approaching vessels about navigational hazards. Imagine a scenario where two ships are travelling towards each other in dense fog . As visibility drops to mere meters, relying solely on visual cues becomes futile. In such situations, blasts from horns take center stage. The prescribed sounds indicate maneuvers like altering course or reducing speed, thereby preventing collisions even when visibility is almost non-existent.

Emergency Situations: Swift Action Saves Lives In times of distress or imminent danger, quick and clear communication becomes paramount. Marine horn signals prove invaluable during emergency situations at sea. Each type of signal has a specific meaning understood universally by those who spend their lives navigating through treacherous waters .

For instance, sounding one prolonged blast signifies an intent to overtake another vessel from its starboard side; three short blasts warn nearby ships that they are operating under restricted maneuverability; and five short blasts indicate danger or lack of understanding with another vessel’s intentions.

Compliance with Regulations: Order amidst Chaos To maintain order amidst chaos on busy waterways, adherence to marine regulations is imperative. These regulations lay down specific rules regarding different types of vessels and their respective soundings. By following these guidelines, vessels can ensure a consistent and standardized approach to signaling. This not only avoids confusion but also allows sailors to anticipate the actions of other ships, resulting in smooth and efficient navigation .

Safety Culture: Prevention is better than Cure Marine horn signals play an essential role in fostering a safety-first culture among seafarers. By adhering to prescribed signal patterns, every sailor demonstrates their commitment to maintaining safety standards at sea. Furthermore, these signals serve as a reminder that being proactive and vigilant is always preferable to finding oneself amidst chaos or disaster.

In conclusion, marine horn signals are not just noise-making devices; they are the backbone of maritime communication and safety. Whether it’s warning about navigational hazards, averting collisions or promoting orderliness on waterways, these signals ensure that every voyage proceeds without endangering lives or property. So, the next time you hear the distinct sound of a marine horn signal reverberating across the ocean, remember its significance in keeping sailors safe and securing smooth sailing for all.

Expert Advice on Navigating with Confidence Using Marine Horn Signals

Title: Mastering Maritime Communication: Expert Advice on Navigating with Confidence Using Marine Horn Signals

Introduction: Navigating through the vast oceanic expanses can be a daunting task for any seafarer. However, armed with knowledge and expertise, mariners can conquer these challenges and sail through the waves with confidence. Among the various tools available for effective communication at sea, marine horn signals hold a crucial place. In this blog post, we delve into the intricacies of marine horn signals to provide expert advice on navigating with unwavering assurance.

Understanding Marine Horn Signals: Marine horn signals serve as an indispensable means of communication between vessels in open waters or congested harbors where visual cues may not suffice. With a combination of short and long blasts of varying lengths, frequencies, and patterns, boats communicate their intentions or warnings to nearby vessels .

Signal Types and Their Meaning: 1. The Short Blast (1-2 seconds): A singular short blast signifies intent to change course to starboard (right), while two short blasts imply changing course to port (left).

2. The Long Blast (4-6 seconds): Emitting one prolonged blast every two minutes equates to making your presence known during periods of reduced visibility such as fog.

3. Five Short Blasts: This universally recognized signal denotes doubt or confusion regarding the intentions or actions of another vessel.

4. One Prolonged Blast Followed by Two Short Blasts: An imminent risk is conveyed when this sequence is sounded, demanding immediate attention from all vessels in the vicinity.

5. Rapidly Repeated Short Blasts: Used exclusively by law enforcement or coast guard vessels as an indication for potential peril; it advises other ships to maintain a safe distance as assistance might be required.

Navigational Scenarios for Successful Communication: 1. Crossing Paths Confidently: When maneuvering across paths with another vessel without proper visual contact, harmonizing horn signals can prevent potential collisions. A common practice is to sound one short blast to signify your intention to maintain the starboard course while allowing the other vessel’s two short blasts to indicate its plan of action.

2. Approaching Head-On or Nearly So: In circumstances where two vessels approach each other head-on, both should sound a series of one short blast, indicating their agreement to pass on the port side (left). Mirroring these horn signals facilitates a safe passage while maintaining professional decorum.

3. Overtaking Another Vessel: As the overtaking vessel, you must produce two long blasts to notify the slower-moving ship that you intend to pass it on its starboard side. The slower vessel acknowledges by sounding no signal , signifying awareness and consent for overtaking.

Conclusion: Efficient communication is vital for ensuring maritime safety and avoiding hazardous situations at sea . Mastering marine horn signals empowers mariners with confidence, enabling them to navigate waterways seamlessly and expertly respond to potential risks. Our expert advice sets sail alongside your ambitions, urging all seafarers alike to prioritize this invaluable aspect of maritime proficiency. So go forth into uncharted waters armed with newfound knowledge and make marine horn signals your ally in conquering the vast oceanic realm!

How Do Cruise Ship Horns Work?

By Michael Ferguson

A cruise ship horn is a powerful sound-producing device used to alert other vessels of its presence or to announce its departure. Cruise ship horns are often heard in ports and along coastal areas, giving the distinctive sound of a ship’s presence.

Cruise ship horns are typically constructed from brass or steel and require pressurized air to activate. When the air pressure is released, the sound of the horn reverberates throughout the area.

The most common type of cruise ship horn is a multiple-note diaphone horn, which produces multiple tones simultaneously when activated. These horns are made up of two chambers — one that produces a low-frequency tone and another that produces a high-frequency tone. The low-frequency chamber is usually made up of several metal pipes, while the high-frequency chamber contains several metal discs that vibrate to produce different tones when air is forced through them.

Cruise ships also use other types of horns such as air horns, steam whistles, and sirens. Air horns produce a single short blast when activated, while steam whistles create an extended tone by releasing steam from a boiler into an enclosed chamber. Sirens are often used on larger vessels for navigation purposes and can be heard for miles away when activated.

Cruise ships use multiple methods to power their horns, including electric motors, compressed air tanks, and diesel engines. Electric motors use electric current from batteries or generators to activate the horn’s diaphragm and create sound waves which travel through the water and can be heard by other vessels nearby.

Compressed air tanks store pressurized air which is then released into the diaphragm’s chambers to create sound waves when needed. Diesel engines are used on larger vessels as they can provide enough power to activate even the largest cruise ship horns without draining too much energy from other onboard systems.

Five (Or More) Short Blasts – On Sounding The Danger Signal

Share this article.

This is PART 3 of a series about the COLREGs. Scroll down for links to Part 1 & 2 

by  Captain  Grant H. Livingstone   The Grand Daddy of COLREGs debate and interpretation among professional mariners may be Rule 34; traditionally called the ‘Danger Signal’ five short blasts on the ships whistle.  I have sailed with professional mariners that would sound five short blasts at everything and those that would only sound five short blasts when they believed collision was eminent.  Many times sounding five short blasts only confounds private boaters who do not understand its meaning.  There are circumstances where professional mariners hesitate to sound any signal fearing the small boat will turn the wrong way.  

Sheer Will: The Story of the Port of Houston and the Houston Ship Channell

I used the term ‘Danger Signal’ on the bridge and when I sounded five short blasts that meant potential danger of collision in my mind.    After conferring with esteemed colleagues who are expert, my view of Rule 34 has evolved and it may be worth discussion.  

 Rule 34 (d) is clear.  When vessels in sight of one another fail to understand the intentions or actions of the other, or is in DOUBT whether sufficient action is being taken by the other to avoid collision, the vessel in DOUBT shall immediately show such DOUBT by giving at least five short rapid blasts on the ships whistle.  

Failing to understand the actions or intentions of the other may arguably exist without risk of collision. Initially under that circumstance we have time to wait and assess after sounding five short blasts.  Assuming we are the stand on vessel we maintain course and speed.  After time to assess, if the other vessel does not appear to be taking sufficient action to give way or avoid collision and we are still in doubt Rule 7(a) directs us to consider that risk of collisions exits.  This is when action to avoid collision, Rule 8, can become a sticky wicket.  Time may be running out for proper and sufficient action to avoid collision.  In many close quarters situations the mariner would need a crystal ball to know if the give way vessel was going to clear safely (avoiding a collision) before ‘crossing bows’.  But Rule 8(e) is clear; if necessary to avoid collision or allow more time to assess the situation a vessel shall slacken her speed or take all way off by stopping and reversing her means of propulsion.  “If necessary” is highly subjective and possibly very difficult to assess until after the fact.  Perhaps there will be no collision and therefore no need to make large course alterations or slacken speed and take all way off.  But if there is a collision after sounding five short blasts and the mariner did not take sufficient action to avoid collision they will be held at fault; severely so.

In conclusion it may not be necessary to slacken speed or change course or take all way after sounding five short blasts when risk of collision is deemed to exit.  But it is Prudent Seamanship to take some action and may, one time out of one thousand, save a professional mariners career and possibly live(s).  

Many thanks to Pacific Maritime Institute’s Bill Anderson Jr., Gregg Trunnell and Steve Burtchael for their invaluable advice on COLREGS.

Deciphering Sound Signals at Sea for Maneuvering & Warning

Large or small … sound signals at the ready! Photo: Keith Skipper/Wikipedia

So Caribbean you can almost Taste the Rum!

Whistle sound signals at sea come in two varieties, according to the international regulations for preventing collisions at sea (irpcs) : a short blast and a prolonged blast used for maneuvering and warning..

  • The short blast means a blast of about one second’s duration,
  • while a prolonged blast is four to six seconds long.

Think of these two different types of blasts as options to use in combinations.

Rule 34 of COLREGS describes maneuvering and warning signals for vessels.

In international waters, when a power driven vessel is underway and in sight of other boats and ships, the following whistles indicate its maneuvers ….

  • One short blast: I am altering my course to starboard.
  • Two short blasts: I am altering my course to port.
  • Three short blasts: I am operating astern propulsion.

Operating astern propulsion does not mean that the vessel is already making way in reverse. It is an alert that the thrust has been reversed and the vessel expects to be going backward soon. The heavier the vessel, the longer it will take to gather sternway.

FIVE or more short blasts are used when vessels are approaching in sight of one another and the intentions or actions of one of the vessels is not understood by the other. Another reason to use this signal is when in doubt that a potential collision will be avoided . If danger lurks, think of signaling at least ‘five short and rapid blasts on the whistle’ to the other vessel.

One additional warning signal is covered in this rule …

It ain't like we are getting married....

A vessel nearing a bend or an area of a channel or fairway where other vessels may be obscured by an intervening obstruction shall sound one prolonged blast. Such signal shall be answered with a prolonged blast by any approaching vessel that may be within hearing around the bend or behind the intervening obstruction.

If you have ever driven the road to Hana on Maui, it is the exact same tactic you use with your car’s horn.

The international version of Rules of the Road doesn’t require that the port or starboard maneuvering signals be answered.

However, the U.S. Inland Rules do make provisions for agreement by the other vessel. For maneuvering port or starboard, the IRPCS is understood to mean that a powerboat unilaterally acts (I am altering my course), while the Inland Rules of the Road require that a powerboat ask for permission (I intend to alter my course).

When overtaking in a narrow channel or fairway, the International Navigation Rules do require that the overtaking vessel wait for agreement by the vessel being overtaken before it commits to safe passing from the stern. The overtaking yacht will sound the following signals …

  • Two prolonged blasts followed by one short blast: I intend to overtake you on your starboard side.
  • Two prolonged blasts followed by two short blasts: I intend to overtake you on your port side.

The overtaken yacht shall indicate her agreement by the following signal on her whistle …

  • One prolonged, one short, one prolonged and one short blast, in that order.

If in doubt, the overtaken yacht can sound the danger signal. The U.S. Inland Rules for overtaking in a narrow channel are similar in concept, but not identical in signals, to the international version.

What constitutes narrow channels? The IRPCS does not contain a specific definition, but admiralty law judges have ruled and local harbor pilots generally agree that it is a buoyed channel. In addition to the width of the channel, the overall size of the vessels in the fairway and their maneuverability must also be taken into account.

The next article in this series will review sound signals for vessels operating in conditions of restricted visibility .

Does 3 short/1 long horn blasts have a special meaning?

Daghis

By Daghis , June 18, 2012 in Royal Caribbean International

Recommended Posts

5,000+ Club

Now that the Port Canaveral Webcam has audio, I've been thrilled to hear ships like the Monarch of the Seas sounding their horn as they passed by the webcam. I noticed that the past couple times I watched her, there were three short blasts followed by one long blast of the ship's horn.

I did some Google searching, but I couldn't find a specific definition for 3 short/1 long. The closest I could find was 3 short by itself which meant that the ship was going to start moving astern, which clearly doesn't apply to a ship heading forward to leave port.

Does anyone know if there is a special meaning for this combination? I'm figuring that it may be possible that it's not a standard combination and is being used as a greeting. In which case, I am thrilled that the Master of the ship is deciding to say hello to those of us on the webcam.

I haven't noticed it from other ships yet, just the Monarch of the Seas. She should be departing soon from Port Canaveral, so if you tune in right away, you might hear the horn on the webcam today.

One short blast means 'I am changing course to starboard.'

Two short blasts mean 'I am changing course to port.'

Three short blasts mean 'I am operating astern.'

Two prolonged blasts followed by one short blast to mean 'I intend to overtake you on your starboard side';

Two prolonged blasts followed by two short blasts to mean 'I intend to over-take you on your port side.'

A long blast every two minutes is used when operating in fog.

Capt_BJ

if a ship is departing a pier by going astern in US inland waters they will typically sound

one prolonged blast (4 to 6 seconds, rule 32c) indicating leaving dock or berth, rule 34g

three short (about 1 second, rule 32b) indicating my engines are operating astern . . .

when I was on one of the 1000 ton cutters there in PC, we left the pier by springing out the stern then backing away from the pier and the standard line as the engines were kicked into reverse and the last line taken in:

"quartermaster, sound one prolonged and three short blasts"

you are correct that when a ship like MONARCH passes FishLips - where the port cam is, neither of these situations apply and the whistle is being used technically - inappropraitely . Basically they are tooting the horn for fun and no one is going to do anything about that except in the rare case of a noise complaint.

One exception could happen .... if a ship sounding such sounds without reason and outside of the rules were to be involved in a collision with another vessel, the wrong sound signals could be a legal issue in a court attempting to determine who was at fault . . . rare but there is case law (according to the rather intense Rules of the Road course I took a long time ago where we studied the rules to pass the CG test for 20 hours, and case law for practical application for 20 hours!)

It means "It's time for you to haul yourself down here and take another cruise!"

a boat powering through the waves

Navigation Sounds

Just as lights play a significant role in understanding what other boats are doing, so do sounds. understanding what you hear is another step towards being a "complete mariner". virtually every boat is required to have some sound producing device. there is a great deal of latitude in what type of sound making device you choose, but loud is good, legal requirements.

Equipment for Sound Signals is based on the length of your boat as follows.

  • Boats less than 39.4 feet in length - must carry an efficient sound producing device. In general, this may be a bell, whistle, or air horn. Though guns--even pots and pans--can make a suitable sound signal useful in getting attention in an emergency, you should always carry the appropriate equipment.
  • Boats at least 39.4 feet to less than 65.6 feet in length - Must carry a whistle and a bell. The whistle must be audible for 1/2 nautical mile. The mouth of the bell must be at least 7.87 inches in diameter.

When and How to Sound Off

Sound signals are to be used only when vessels are in sight of each other and are meeting or crossing at a distance within half a mile of each other. These signals must never be used in fog or other conditions of reduced visibility, where the vessels are not visible to each other by eye. Only the fog signals listed under the Inland Rules, Rule 35 may be sounded at such time.

Sound signals are called "blasts". There are two different blasts used for warning and steering signals.

  • Short Blast - Lasts about one second.
  • Prolonged Blast - Lasts from four to six seconds.

Maneuvering Signals

There are different blasts combinations for various movements on the water that may use both short and prolonged blasts. When power-driven vessels are in sight of one another and meeting or crossing at a distance within half a mile of each other, each vessel underway, when maneuvering as authorized or required by the Inland rules must use the following sound signals.

  • One Short Blast - This means "I intend to leave you on MY port side". When you pass near another boat, you will manuever by leaving them on your left side as you pass. If you are behind another boat, going the same direction and about to overtake it, one short blast means: "I intend to pass you on YOUR starboard side, MY port side".
  • One Prolonged Blast - This means you are leaving a dock or departing your slip. It signals to others a change in status and that you are getting underway. A prolonged blast is also sounded when a vessel is approaching a bend in a river where vessels coming from another direction cannot be seen. It is sometimes referred to as the “blind bend signal".
  • Two Short Blasts - This means "I intend to leave you on MY starboard side". When you pass near another boat, you will manuever by leaving them on your right side as you pass. If you are behind another boat, going the same direction and about to overtake it, two short blasts means: "I intend to pass you on YOUR port side, MY starboard side."
  • Three Short Blasts - This means you are operating in astern propulsion, for example backing away from a dock
  • One Prolonged Blast + Three Short Blasts – This is technically two different signals in succession. One prolonged blast indicates you are getting under way, and three short blasts indicate you are backing up. This is what is sounded when you are departing a dock in reverse.
  • Five Short Blasts - This is the DANGER signal. Remember, that when you approach another vessel and hear either one or two short blasts, and you both understand their signal and can safely let them do it, then you are required to respond with the same signal in response. However, if you don't understand their intentions, or feel that their proposed maneuver is dangerous to either vessel, then you are required to sound the DANGER signal.

Note: Inland Rules regarding sound signals are occasionally different from International Rules. Inland Rules signal intended action and International Rules signal what you are actually doing. The following information reflects Inland Rules. If you travel overseas, you must learn the International Rules.

Proper Sound Signals

Passing port to port.

When you meet an oncoming vessel, and wish to pass port to port, you are required to sound one short blast with your horn. If the other boat is in agreement, they should respond with a similar blast.

Passing Starboard to Starboard

If you approach another vessel head on, and wish to pass it on its starboard side, you are required to sound two short blasts with your horn. If the other vessel is in agreement, they should sound the same signal in response.

Overtaking on Portside

When you are planning on passing another vessel from behind, there are several things you must do. Any vessel that is overtaking another must keep out of the way of the vessel being overtaken. This means that you can't expect them to move, slow down, or change their course. If you plan on passing them on THEIR starboard side, you must sound one short blast. If they understand your signal and agree, they will sound one short blast in response. The vessel being overtaken has a responsibility to maintain course and speed in order to minimize the potential for collision.

Overtaking on Starboard

When you are planning on passing another vessel from behind, there are several things you must do. Any vessel that is overtaking another must keep out of the way of the vessel being overtaken. This means that you can't expect them to move, slow down, or change their course. If you plan on passing them on THEIR PORT side, you must sound two short blasts. If they understand your signal and agree, they will sound two short blasts in response. The vessel being overtaken has a responsibility to maintain course and speed in order to minimize the potential for collision.

Note: These are not the only rules concerning sound signals in restricted visibility; there are additional rules concerning sound signals that may be found in the Rules of the Road or in Chapman's Piloting.
