Cruise Ship Cruising Speed

How fast is a cruise ship, which is the fastest cruise ship in the world? Read all about the cruise ship speed (average/top cruising speed) which is generally measured in knots, but also in mph/kph. This page is integrated with our surveys on ship dimensions , ship propulsion/engines, power and our cruise tracker (current positions).

How fast is the fastest cruise ship in the world?

Cunard Line 's Transatlantic liner RMS Queen Mary 2 (QM2) weighs almost 151,500 tons, with a cruising speed of 29 knots (33,5 mph / 54 kph). This unique vessel is the only currently operational Atlantic Ocean liner crossing weekly the huge distance between Southampton (Great Britain's maritime capital) and NYC New York USA (world's financial capital). The below photo shows an engine room telegraph (aka engine order telegraph or Chadburn). This device was used on older ships and submarines for communication between Navigation Bridge and Engine Room, where crew powered the vessel at certain (fixed) speeds.

QM2's Transatlantic crossing distance is almost 3,000 nautical miles, or ~3,400 statutes/normal miles (5,500 km), and this is done in less than 7 days. The world's most famous ocean liner (maybe after RMS Titanic ) has an exterior deck space of 14,200 m2 for passengers to enjoy the "fastest sea ride" ever, and, of course, transparent windscreens to shield them at the high speeds.

The world's second-fastest cruise ship is MS Voyager (last named Costa Voyager ), now owned and operated by a Chinese company. Liner's service speed is 28 Kn (32 mph - 51,5 kph). But there's a trick - this vessel weights just 24,400 tons. In comparison, the world's largest cruise ships - Royal Caribbean's Oasis-Class (nearly 225,300 tons each) cruise with an average speed of 20 knots (23 mph / 37 kph) and can go with "top speed" 22,5 Kn (26 mph / 42 kph).

The world's third-fastest cruise ship is P&O Oriana (now Piano Land) . In 1997, it won the "Golden Cockerel" award for being the company's fastest vessel - accomplishing a maximum cruising speed of 26,2 Kn (31 mph / 50 kph).

Cruising Speed

By definition, the term "cruising speed" signifies the speed for any vehicle (could be cars, ships, aircraft) and it's usually about a speed somewhat below the maximum (as specified by the manufacturer) that is comfortable, but also economical.

Generally, modern cruise ships don't have to be fast - it's not necessary at all. Instead, the new cruisers' demand is for big vessels (as tonnage and passenger capacity), stable and safe (related to propulsion and generators), comfortable, regular as departures, excitingly thrilling as to onboard activities and amenities, and also alluringly tempting as itineraries. And the latest trend is cruise ships also must be more and more fuel-efficient.

For bigger ships, the optimum cruising speed is 20-22 Kn (23 mph / 37 kph). Bigger passenger ships have a large draft (the "invisible" part of the vessel, beneath the waterline), which causes huge resistance and hampers "fast and furious at sea" performances. In return for it, drafts of 23-30 ft (7-9 m) allow smooth rides when traveling even with 25-27 mph (over 40 kph). The vessel's close to top speed cruising is generally used when avoiding storms (especially during the Caribbean summers), during tests, and sometimes when assisting other vessels.

The speed of cruise ships is measured in knots (Kn), 1 knot is 1 nautical mile per hour. Cruise help - for the "normal" speed values, multiply knots by 1,15  (mph), or 1,852 (kph). Below, you may compare the average passenger ship speed in the huge fleets of several big cruise ship companies and lines.

The knot is a nautical term, meaning cruising one hour the distance of one nautical mile. And one nautical mile (by the contemporary world standards) equals 1,15 statue (or "land") miles (6,080 "modern" feet) or 1,852 kilometers. So, to convert the speed values of ships (and riverboats, and of whatever floats) simply multiply knots by the above constants. Worldwide, the knot speed measuring is also used in meteorology and air navigation.

Cruise ship speed (knots to mph/kph conversion)

Speed of cruise ships in knots (kn), miles per hour (mph) and kilometres per hour (kph).

The cruise ship top speed is 2-3 knots higher than its service speed, and it's required rarely - in cases of emergencies (to avoid storms or on rescue operations) and during tests. The average speed of cruise ships is about 20-24 knots. But if you really need the details - well, enjoy the data from our table!

What is the maximum wind strength a cruise ship can withstand?

Cruise ships are marvels of modern engineering, capable of traveling the world’s oceans with ease and comfort. However, these massive vessels are also subject to the forces of nature, including wind and waves. One question that often arises when planning a cruise is,?

The answer to this question depends on several factors, including the size and design of the ship, the conditions of the sea and wind, and the experience and training of the crew.

Generally, modern cruise ships are equipped to handle winds of up to 50 knots, or approximately 57 miles per hour. However, some ships may be able to withstand higher wind speeds, especially if they are designed to sail in rough seas or adverse weather conditions.

The key to a ship’s ability to withstand high winds is its stability. Cruise ships are designed to be stable in a variety of sea conditions, using features such as stabilizers and ballast tanks to keep the ship upright and level. In addition, modern cruise ships are equipped with sophisticated navigation and monitoring systems that can detect changes in wind and sea conditions and adjust the ship’s speed and course accordingly.

Despite these precautions, it is still possible for a cruise ship to encounter high winds and waves that exceed its design limits. In such cases, the crew will take appropriate measures to ensure the safety of the passengers and the ship. This may include altering course, reducing speed, or even stopping the ship until the adverse weather conditions pass.

In summary, the maximum wind strength a cruise ship can withstand depends on a variety of factors. While modern ships are designed to be stable in adverse weather conditions, it is still important for passengers to be aware of the risks and to follow the instructions of the crew in case of inclement weather. By doing so, passengers can enjoy a safe and comfortable cruise experience, even in the midst of a stormy sea.

What Is Considered Rough Seas For A Cruise Ship: A Clear Explanation

by Judith Eve | Aug 27, 2023 | Cruise Travel Tips

I have encountered rough seas on cruises before. I am grateful that I usually do not get seasick.

When planning a cruise, one of the concerns that passengers may have is the possibility of encountering rough seas. While cruise ships are designed to handle a variety of weather conditions, it is important to know what is considered rough seas and what to expect.

According to the Douglas Sea Scale, waves that are over eight feet (2.4m) are considered rough, while waves over 13 feet (4m) are classified as very rough. At a Beaufort scale of 7 or more, which corresponds to wind speeds of 32 to 38 mph and wave heights of 13 feet, the sea is also considered rough. During these conditions, sea heaps up and foam begins to streak, and whole trees may be in motion on land.

While rough seas can be uncomfortable for some passengers, it is important to note that cruise ships are designed to handle these conditions. The captain will do everything possible to avoid bad weather by steering the ship away from storms or rough seas when possible. However, it is not always possible to avoid these conditions, and passengers should be prepared for the possibility of rough seas during their cruise.

Understanding Rough Seas

Rough seas can be a challenge for cruise ships and their passengers. Understanding what is considered rough seas for a cruise ship is important to ensure the safety and comfort of everyone on board. Waves, wind, and other factors can create rough seas that can make a cruise uncomfortable or even dangerous.

The Douglas sea scale is a system that measures the height of waves. When waves reach a height of over eight feet (2.4m), the sea is considered to be 'rough'. If waves are over 13 feet (4m), then the sea is classified as 'very rough'. This scale is used by many cruise lines to determine when it is safe to sail and whether passengers should be advised to stay in their cabins.

While the Douglas sea scale is a useful tool, there are other factors that can contribute to rough seas. Wind speed and direction can affect the height and frequency of waves. The size and weight of the ship can also impact how it handles rough seas. A larger ship may be able to handle rough seas better than a smaller one.

When a cruise ship encounters rough seas, the crew will take steps to ensure the safety and comfort of the passengers. This may include adjusting the ship's speed or course to avoid the worst of the waves. They may also advise passengers to stay in their cabins or avoid certain areas of the ship.

It is important to note that rough seas are not always avoidable. The ocean can be unpredictable, and even the most experienced sailors can encounter rough waters. However, cruise ships are designed and built to withstand a wide range of conditions, including rough seas. By understanding what is considered rough seas for a cruise ship and how ships handle these conditions, passengers can feel confident and safe during their voyage.

Impact of Rough Seas on Cruise Ships

Cruise ships are designed to withstand rough seas and adverse weather conditions. However, when the seas become too rough, it can impact the comfort and safety of passengers and crew.

One of the main effects of rough seas on a cruise ship is the rolling and pitching motion. The ship may rock from side to side, causing discomfort and seasickness for some passengers. The rolling motion can also cause objects to shift and fall, leading to potential safety hazards.

To counteract the rolling and pitching motion, most modern cruise ships are equipped with stabilizers or stabilisers. These are fins or wings that extend from the sides of the ship and help reduce the rolling motion. The stabilizers work by creating resistance against the water, which helps keep the ship steady.

Despite the presence of stabilizers, extreme weather conditions can still cause a cruise ship to roll and pitch. In such cases, the captain may decide to alter the ship's course or reduce its speed to minimize the impact of the rough seas.

It is important to note that what constitutes rough seas is subjective and can vary depending on factors such as the size of the ship, the experience of the crew, and the weather conditions. However, in general, waves with a height of 8 to 13 feet can be considered rough for a cruise ship.

Geographical Considerations

When it comes to rough seas, the geographical location of a cruise ship plays a significant role in determining the level of roughness. Here are some of the areas that are known for rough seas:

Caribbean and Bahamas

The Caribbean and Bahamas are famous for their sunny weather and calm waters. However, during hurricane season, which runs from June to November, the region experiences rough seas due to the tropical storms and hurricanes that occur. The Bay of Biscay, located in the North Atlantic, is another area that can be rough due to the strong winds and currents.

North Atlantic and Bermuda

The North Atlantic and Bermuda are known for their unpredictable weather patterns, which can lead to rough seas. The area is prone to storms and gales that can cause large waves and choppy waters.

Mediterranean

The Mediterranean is generally calm, but it can experience rough seas during the winter months due to strong winds. The region is also known for its sudden and unpredictable storms.

Alaska and Gulf of Alaska

Alaska and the Gulf of Alaska are known for their cold waters and rough seas. The area is prone to storms, and the strong currents and winds can cause large waves that can be challenging for cruise ships to navigate.

Drake Passage and Antarctica

The Drake Passage, located between Cape Horn and the South Shetland Islands, is notorious for its rough seas. The passage is the shortest crossing between Antarctica and the rest of the world, and it connects the Atlantic and Pacific Oceans. The area is known for its strong winds and currents that can cause large waves.

South China Sea

The South China Sea is prone to typhoons, which can cause rough seas and high waves. The area is also known for its sudden storms, which can be challenging for cruise ships to navigate.

Open water, such as the Atlantic and Pacific Oceans, can also experience rough seas due to storms and strong winds. However, modern cruise ships are equipped with advanced stabilizers that can minimize the impact of rough seas.

Overall, the level of roughness at sea is affected by various factors such as wind speed, wave size, and currents. It is essential for cruise ships to be equipped with advanced technology that can help them navigate through rough seas safely.

Time of Year and Weather Conditions

When it comes to determining what is considered rough seas for a cruise ship, the time of year and weather conditions play a significant role. Certain times of the year are more prone to rough seas due to weather patterns and seasonal changes.

Winter months, especially from May through July, tend to experience the most frequent gale-strength winds. The currents, combined with the directional shift in the landmass from south to east, create rocky seas year-round. However, rough seas can still be possible in the Mediterranean and other regions during the early spring months.

Hurricane season, which typically runs from June through November in the Atlantic, can also create poor weather conditions and rough seas. It is important to note that while hurricanes can pose a significant threat to cruise ships, cruise lines closely monitor weather patterns and will alter their routes to avoid severe weather conditions.

Wind speeds can also contribute to rough seas. When waves reach a height of over eight feet (2.4m), the sea is considered to be "rough." If waves are over 13 feet (4m), then the sea is classified as "very rough." The Douglas sea scale is a system for measuring the height of waves and is used to determine the severity of sea conditions.

Cruise Ship Safety Measures

Cruise ships are some of the safest modes of transportation available. Cruise lines must follow a surprising number of rules and regulations to protect their passengers. They take safety very seriously, and their ships are equipped with the latest technology to ensure a safe voyage.

The captain of a cruise ship is responsible for the safety of all passengers and crew. They have the authority to make decisions regarding the itinerary and the ship's operations, including changes due to bad weather. They are trained to handle all kinds of situations, including rough seas, and will take necessary precautions to ensure the safety of everyone on board.

Cruise ships are designed with safety in mind. They have advanced stabilizers that help to reduce the ship's movement in rough seas, making for a smoother ride. In addition, they are equipped with the latest in weather tracking technology to avoid bad weather and rough seas whenever possible.

Cruise lines also have strict safety protocols in place. They conduct regular safety drills to ensure that passengers and crew know what to do in case of an emergency. Lifeboats and life jackets are readily available, and passengers are required to attend a safety briefing before the ship sets sail.

In the event of bad weather, the captain may make changes to the itinerary to avoid rough seas. This may include changing the route or delaying the ship's departure. Passengers should always listen to the captain's instructions and exercise caution when walking around the ship during rough seas.

Overall, cruise ship safety is taken very seriously, and passengers can feel confident that they are in good hands. With advanced technology, trained crew members, and strict safety protocols, cruise lines do everything they can to ensure a safe and enjoyable voyage for everyone on board.

Dealing with Seasickness

Seasickness, also known as motion sickness, is a common concern for many cruise ship passengers. It is caused by the motion of the ship on the water, which can cause the inner ear to sense movement that the eyes cannot see. Symptoms of seasickness include nausea, dizziness, and vomiting.

Fortunately, there are several ways to deal with seasickness. One option is medication. Over-the-counter pills such as Dramamine or Bonine can help alleviate symptoms. Prescription medications such as scopolamine patches can also be effective.

Some people prefer natural remedies, such as eating green apples or using acupressure wristbands. While there is little scientific evidence to support these methods, some people find them helpful.

In addition to medication and natural remedies, there are several other strategies for dealing with seasickness. One is to stay hydrated and avoid alcohol, which can make symptoms worse. Another is to focus on the horizon or other stable objects to help the brain adjust to the motion of the ship.

Cruising Experiences

When it comes to cruising, rough seas can be a concern for many passengers. While some may enjoy the thrill of a bit of rocking and rolling, others may feel uneasy or even seasick. So, what exactly is considered rough seas for a cruise ship?

According to the Douglas Sea Scale, which is a system for measuring the height of waves, a sea is considered rough when waves reach a height of over eight feet (2.4m). If waves are over 13 feet (4m), then the sea is classified as very rough. However, it's important to note that other factors, such as wind and weather conditions, can also impact the roughness of the sea.

Cruising experiences can vary greatly depending on the destination and season. For example, Antarctica cruises and Alaska cruises may encounter rough seas due to their remote locations and unpredictable weather patterns. Transatlantic and transpacific cruises, which cross large bodies of water, may also experience rough seas at certain times of the year.

When it comes to choosing a cabin, some passengers may prefer to book a balcony room to enjoy the view, while others may opt for a lower deck to minimize the effects of rough seas. It's important to note that even on a lower deck, passengers may still feel some movement, but it may be less noticeable.

Overall, cruising experiences with rough seas can vary greatly depending on a variety of factors. While it's impossible to predict the exact conditions of the sea, cruise lines typically monitor weather patterns and adjust itineraries accordingly to ensure the safety and comfort of their passengers.

While I have experienced rough seas on cruises, it usually does not last long, and the majority of the cruise is usually smooth sailing.

Windy on deck?

By eliminnowp , May 14, 2014 in First Time Cruisers

Recommended Posts

How windy does it get on deck on an average cruising day?

I plan on having layers and a jacket (we're headed to Alaska), but I have long hair and need to know if I should plan to keep it tied back.

If your hair blowing around will bother you, I would plan to keep it tied back. It can get pretty windy on deck.

Depends on which deck and where you are! But if you're going to Alaska, so much is in the viewing as you sail by, that you will probably want to be on deck, near a rail, a lot of the time...and it could be very windy, depending on how fast the wind is blowing and from which direction, and how fast the ship is moving. I'd plan to tie your hair back.

It certainly can get very windy.

At the railing, it's very windy when the ship is underway. If you step about 4-6 steps back, the wind is greatly reduced.

My hair is in a ponytail almost all day long...just easier. At night, I get "gussied up" and simply don't go out into the wind!

If there is a light breeze - say five miles per hour and the ship is moving at 20 miles per hour into the breeze, you will feel a 25 mph wind. Or, if there is a strong breeze, say 20 mph, and the ship is moving the same 20 mph in the same direction, you will feel no movement of air at all.

The answer - like much else about cruising - is "it depends".

Thank you all for the info. I guess I should pack some hair ties and clips so I don't end up looking like a windblown mess :) I plan on spending a lot of time out looking at the scenery.

Just put a scrunchie or a covered elastic around your wrist ; you can whip your hair into a ponytail at a moment's notice. That's what I used to do.

It is only windy in the daytime and after dark.

Any wind which fluffs you up will hit everyone around you - Alaska is too great an experience to worry about a few displaced strands - besides,,it feels great to gave the wind in your face.

Yes, but I will add that for a woman with long hair, it can be difficult to manage it after said windy experience. I fully understand where OP is coming from. :)

It is a simple matter of relativity.

If the wind is blowing towards you at 20 knots and the ship is going at 20 knots, you are feeling a 40 knot wind into your face.

If the wind is blowing away from you at 20 knots and the ship is going at 20 knots, you feel no effective wind.

If the wind is at an angle to you, the wind you feel depends upon the direction of the wind.

It is a simple application of vector mathematics. You can also figure it out using triangles.

You mean you don't know vector arithmetic? :eek:

I might. My Geek Meter sits in the red. Friends only comment when it pins.

On a serious note, even if most people do not know the math involved, they do understand how ship speed and direction and overall wind speed and direction can come together to mess their hair.

We took our teenage daughter on her first cruise last year, and she experienced a hair disaster!

She asked one evening if she could go play basketball with her friends, and I said yes, and asked if she was going to braid her hair before going [her hair is waist length]. She said no, it will be fine.

Fast forward a couple of hours and my daughter returns from the upper deck, only to spend an hour in the bathroom de-tangling her hair! It looked like an enormous afro!

After that evening, she always put her hair in braids or a twist before venturing to the upper/outer decks.

In addition to hair, you should be mindful of earrings - especially dangle earrings. On my first cruise, the wind on deck whipped one out of my ear.

I still wear dangle earrings on the ship, but I carry a small jewelry box with me. If I go out on deck, and the wind is especially strong, I take the earrings out, and put them in the box.

Hats and eye/sun glasses have also been know to fly away if the wind is especially strong.

Depends upon 4 factors - the speed of the wind; the speed of the ship; the direction of the wind; and the direction of the ship. To get an accurate answer requires vector math. However, the simplistic answer is that it depends and it can vary from no effective wind at all to really really (think 30 or 40 mph) windy.

I have been there many times, it can get windy.

Its usually pretty windy. i did notice on our last cruise on the Oasis it was windy. wish i would have been one of them cool people with them Boca Clips :D towels were flying all over

Bring whatever you need to hold your hair back. It will be very windy at sea (especially at the very front of the ship) so you will definitely want something strong to hold your hair back.

River cruising...not so much!.Ocean cruising......always.

Whether you need a jacket or not is dependent on the region. Night may be cooler than days again dependent on the region. Ocean=windy;)

Being "follically challenged", It doesn't bother me much. But, I would advise to plan for the worst. Then, you'll be ready for whatever is thrown at you . . .

I have waist-length hair and intend on bringing some hair ties, clips, and pens. I'm one of the lucky ones who's able to put my hair in a secure bun with a chopstick or stick pen :) Maybe some of those bun spirals or similar would be of use. I love those!

How is cruise ship speed measured, and how fast is a knot in miles per hour?

Have you ever wondered how cruise ship speed is measured? Ships aren't the fastest method of transportation, but that doesn't mean it's not fun to calculate your speed when you're sailing. Unlike land travel, ship speed is not measured in miles per hour.

Here, I'll cover how cruise ship speed is measured, how to calculate your ship's speed in miles per hour and some considerations that could affect how fast you're going.

For cruise news, reviews and tips, sign up for TPG's cruise newsletter .

What is a knot in nautical terms?

A knot is the nautical measure of speed used by cruise ships and other maritime vessels. One knot represents 1 nautical mile per hour.

But "knot" isn't simply a misspelled nickname for "naut" (as in nautical mile). Its origins are far more literal, according to the United States' National Ocean Service .

In the 17th century, ship crews measured vessel speed by tossing a rope with several evenly spaced knots and a triangular-shaped piece of wood into the water. As the ship moved, currents created resistance against the wood, causing more rope to be pulled into the water over a specified period of time. When time was up, crew members would pull the rope in and count the knots.

In short, the number of knots pulled out into the water over a specific period of time translated into the speed of the vessel's travel.

How fast is a knot in miles per hour?

When you convert 1 knot to miles per hour, it works out to 1.15 standard miles per hour for every nautical mile per hour. That's knot speed. So, although land-based miles per hour are just slightly faster than knots, for general purposes, it's a close comparison. For example, if your ship is sailing 20 knots, it's sailing roughly 23 mph.

How fast do cruise ships go?

What is the maximum speed of a cruise ship? The maximum speed for most modern vessels is about 30 knots or 34.5 mph, but just because they can glide along that fast doesn't mean they actually do, or at least not all the time.

Officers on the bridge will adjust speed to account for weather and ocean conditions — rough seas and high winds mean slower speeds — and port arrival times. Early arrival into port can come with extra fees that cruise lines are loath to incur, which usually means they prefer to take their time by slowing their speed.

What is the average cruise ship speed?

Cruise ship average speed is affected by lots of outside forces, as mentioned above. In relatively calm conditions, the average present-day vessel travels about 20 knots or 23 mph between ports of call.

What is the fastest cruise ship?

Currently, the fastest cruise ship that's operational is Cunard Line's Queen Mary 2, which often serves as an ocean liner to ferry people back and forth between the U.S. and the United Kingdom. Its maximum speed is 30 knots.

Cunard, which has operated historically fast vessels throughout the years, won the Blue Riband — a coveted prize for the ship to cross between the U.S. and Europe while maintaining the highest speed — 18 times. The last ship in the fleet to hold the unofficial award, which dates back to the 1800s, was Queen Mary, which is currently a floating hotel in Long Beach, California, near Los Angeles.

Queen Mary was dethroned as the winner in 1952 by SS United States, which was operated by rival United States Lines and made the crossing in just three days, 10 hours and 40 minutes at a speed of nearly 35.6 knots or almost 41 mph. (Its maximum speed was 39 knots or about 45 mph.)

Today, SS United States is docked in Philadelphia and maintained by a nonprofit conservancy that hopes to find investors to restore the languishing liner, which is now more than 70 years old. It might not be operational, but its previous accolades make it the fastest passenger vessel currently afloat.

Winds of change: how big cruise ships could use futuristic sails to save fuel

Author: Dave Monk

Published on: 24 May 2023

Updated on: 25 May 2023

A major change in the cruise industry is in the air. Wind propulsion – once confined to sailing ships – could soon be harnessed to help large vessels carrying thousands of passengers to cross the oceans

Pioneering shipyard Chantiers de l’Atlantique, which has built icons such as Queen Mary 2, Wonder of the Seas and Celebrity Beyond, is attracting buyers for its Solid Sail technology – including Orient Express, which is planning to launch the world's largest sailing ship in 2026. Ponant has announced it aims to build an emission-free ship using wind propulsion by 2025. And researchers working on fitting devices such as hard sails, suction wings and rotating cylinders to cargo ships report increased interest from cruise lines. If all this sounds like dreamy designers simply flying a kite, well, flying kites is yet another proposal. With potentially millions of pounds of savings and the urgency of a net-zero goal, what might look now like science fiction could soon become science fact. Of course, lines such as Star Clippers , Windstar and Sea Cloud have been using wind power for years. But, with increasing pressure to cut fossil fuels and costs, large ships could soon be built to harness the free energy source alongside other alternatives such as biofuels, battery cells, solar power and hydrogen.

Advocates of wind power say it could provide more than half the energy of a new ship and up to 20 per cent when retrofitted. Some tankers, ferries and fishing vessels already use the technology and well-known names such as Airbus, Renault and Michelin are involved in research. The technique most likely to be applied to cruise ships is the Solid Sail being developed by Chantiers de l’Atlantique in Saint-Nazaire, France. Like other models being researched, it works on the same principle as plane wings, except it is vertical – providing propulsion rather than lift. Rigs of the hard sails being tested at the port can spin through 360 degrees, stand as high as 230ft, tilt to go under bridges, and concertina down when not in use. The automated system could be controlled by one person on the bridge. An early version of the design was tested by Ponant on its sailing ship Le Ponant in 2018. Chantiers de l’Atlantique has also worked on a prototype called Silenseas, a 623ft-long ‘ship of the future’ that would carry 300 passengers at speeds of up to 17 knots using sails made from sturdy composite materials to supplement dual-fuel engines.

Nicolas Abiven, Solid Sail project manager at Chantiers de l’Atlantique, said: “The first stage of development has finished and Solid Sail is now ready for market. We have several very serious contacts both for cruising and commercial ships markets. “We’re very proud to be one of the first companies to supply very large rigs to modern hybrid-propelled ships in order to reduce environmental impact. The market for wind-power technologies is huge and Solid Sail should be one of the key players.” The technology has been certified by the international body Bureau Veritas, whose technology leader, Aude Leblanc, said: “Solid Sail is exciting as it provides a simple and safe solution to reduce emissions on cruise ships.”

Orient Express's 54-suite ship, Orient Express Silenseas, will be 220 metres long and feature two pools, two restaurants and a speakeasy bar when it launches in 2026. A sister vessel is already on the order books. Ponant is also drawing up plans for its emission-free ship using several green energy sources, including wind propulsion. CEO Hervé Gastinel said: “After launching the first ever hybrid-electric LNG ship, Le Commandant Charcot, investigating wind power was the next logical step. We have the best people working on creating the best of the best, a ship that will help us achieve and continue to work towards our sustainability goal.” Three years ago, MSC Cruises signed a memorandum of understanding with Chantiers de l’Atlantique to develop prototype vessels by 2050 which would “explore opportunities that wind power and other advanced technologies could bring to passenger shipping.” Linden Coppell, the cruise line’s vice president of sustainability, said: “We are totally committed to investigate all potential solutions thoroughly to get us to net zero carbon emissions and wind power is one aspect that we will continue to evaluate.”

The MSC Group is part of a EU-backed research consortium looking at alternative fuels. Ms Coppell said: “As part of the project, fixed sails will be fitted to a bulk carrier and we will be able to better understand how this could possibly be applied to the cruise industry and integrated with other zero-emissions technologies.” Costa Cruises, part of Carnival Corporation, has set up a unit to help achieve zero emissions of its fleet by 2050. Christoph Schladör, vice president of decarbonisation, said: “While on their own, solar and wind energy cannot power a medium or large cruise ship, they can cover a good share of the electricity demand or the propulsion power. All these systems will develop further and take a more significant role in the energy supply of ships.” One project aiming to use the technology is Ecoship, being designed by Peace Boat, based in Japan. Fitted with 10 hard sails, it aims to carry 6,000 people a year on three or four world voyages spreading awareness on climate change. Swedish supergroup, Abba, is also getting on board with the environmental message. Its London concert venue Abba Voyage , featuring avatars of the band, has partnered with Oceanbird, a Stockholm-based company backed by shipping group Wallenius that aims to build its first wind-assisted car carrier by 2026.

Niclas Dahl, managing director of Oceanbird, says the main challenges with using wind power for cruise ships would be stability and the loss of deck space. But, with fuel costs rising, there is a business argument for using a free energy source. He’s already had talks with cruise executives attracted by the need to save money on long journeys – a single fixed vertical wing can save 3,000 barrels of diesel a year. Mr Dahl said: “Wind can deliver substantial savings. If you are going to change the world it must make sense from a business perspective too. However, cruise ships very much use the deck area. They don’t want to get rid of the pool, for example, but I’m sure we can find solutions. “Wind is an opportunity we must seize now. There’s simply no time to waste in phasing out fossil fuels.”

As well as hard sails, other technologies being studied are suction wings – first developed by Jacques Cousteau - – and rotation cylinders, also called Flettner rotors, that are spun by a motor to create lift and propulsion as the wind blows across them. But of all the solutions the most pioneering is the Skytug – a 230ft catamaran fitted with 10 huge kites to haul ships across the oceans with wind power. James McGarley, the managing director of Bluewater Engineering which is developing the technology, said: “I’ve had conversations with cruise operators about Skytug. One big opportunity would be in repositioning transits, moving ships across oceans. On longer offshore legs of certain cruises, it could also be useful, for example to and from Atlantic islands or in similarly windy regions. Cruise will be an interesting area of expansion for us in future.” The International Windship Association, set up in 2014, has more than 150 members, including some of the biggest shipping companies in the world. Secretary general Gavin Allwright said Chantiers de l’Atlantique’s work on Solid Sail was showing promise. “If you had £100million and you walked into Chantiers today you could order Silenseas – although their order books are full. You’d get about 70 per cent of power from the wind there. “With wind, to do a vessel with 500 or 1,000 passengers isn’t such a big ask. The Peace Boat Ecoship is around 2,000 passengers – a fair-sized vessel. If you have a 5,000-passenger ship doing short hops between Mediterranean ports, then wind can be a component but it’s not going to be your primary power.

“One of the big USPs of wind is that, because it’s a free energy source, it pays for itself. I think it’s absolutely practical for the cruise industry, especially if it’s incorporated in that new-build design stage.” About the new Ponant ship, Mr Allwright said: “I met their head of sustainability and said the momentum’s there right now, if you want to be one of the first movers, go for it! I’ve seen a couple of presentations and been impressed with the way they’re moving forward.” He believes the impulse for change might come from increased regulation by the European Union or International Maritime Organization. “I also think there’s going to be pressure from certain groups of passengers, especially young eco-aware travellers and older people who want to go on an environmentally friendly cruise.” The UK’s Clean Maritime Plan predicts that, by 2050, 40 to 45 per cent of the world’s shipping will have some sort of wind assistance. “We think that’s conservative – it could be a lot quicker and a lot higher,” said Mr Allwright. “We can see 100 per cent of the world fleet outfitted in some form if we make the decision to go that way. We could see an entire rethinking of how we do shipping in the future.” Passengers will have a chance to experience new sail technology when French company TransOceanic Wind Transport launches the first of two cargo vessels this year. As well as delivering goods in an environmental way, the ships will be able to carry up to 12 passengers each on odysseys from Le Havre, including a 13-day crossing to New York, two-week sailing to the Ivory Coast or a 55-day epic journey to Shanghai. Fares are expected to be between 160 and 290 euros per person per day. Company president Guillame Le Grand said: “We have had a very strong demand for our sailings, which will be ‘passages’ more than cruises. We think the level of environmental interest is going up rapidly, as well as the search for authenticity.”

• Sustainability

Introduction

Welcome aboard! Cruise ships are a popular choice for vacationers who crave the excitement of exploring the open seas while enjoying the comfort and luxury of a floating resort. These massive vessels offer an array of amenities, from world-class dining options to breathtaking entertainment and relaxation options.

However, as impressive as cruise ships may be, there is one question that often arises in the minds of travelers: How big of waves can a cruise ship handle? This is a valid concern given the unpredictable nature of the ocean and the potential for rough seas.

In this article, we will delve into the intricacies of cruise ship stability and explore the factors that play a role in determining a ship’s ability to handle large waves. We will also discuss the design features that help ensure the safety and comfort of passengers and crew during challenging sea conditions.

Understanding the fundamentals of cruise ship stability is essential for both avid cruisers and those considering a cruise for the first time. By gaining insight into the design and engineering behind these floating marvels, you can better appreciate the efforts taken to create an enjoyable and secure experience while at sea.

So, let’s dive in and explore the fascinating world of cruise ship stability and how these magnificent vessels navigate through even the most challenging of waves.

Understanding cruise ship stability

When it comes to cruise ship safety, stability is of utmost importance. Cruise ships are meticulously designed to maintain stability in a variety of sea conditions, ensuring the safety and comfort of passengers and crew onboard. But what exactly is cruise ship stability?

Stability refers to a ship’s ability to remain upright and steady while floating on water. Cruise ships are built with a low center of gravity, which helps them resist the forces of waves, wind, and other external factors that can cause the ship to roll, pitch, or yaw.

Several key factors contribute to cruise ship stability:

• Metacentric height: The metacentric height is a crucial measurement that determines a ship’s initial stability. It represents the distance between the ship’s center of gravity and its metacenter, which is the point where the vertical line through the center of buoyancy intersects with the line of the center of gravity. A larger metacentric height indicates greater initial stability.
• Weight distribution: To maintain stability, cruise ships need an even distribution of weight throughout the vessel. The weight of accommodations, amenities, and supplies is carefully balanced to prevent excessive listing.
• Buoyancy: The design of the ship’s hull and its displacement in the water contribute to buoyancy, which helps counteract the downward force of gravity. Ships are built with a wide, flat hull to enhance buoyancy and stability.
• Ballast tanks: Cruise ships are equipped with ballast tanks that can be filled with water to adjust the ship’s overall weight distribution. This allows for fine-tuning of stability based on sea conditions.

Together, these factors work in harmony to ensure that cruise ships maintain stability, even in challenging conditions. Advanced technologies, such as stabilizer systems, are also employed to further enhance stability and minimize the ship’s motion.

By understanding the principles of cruise ship stability, passengers can have peace of mind knowing that these floating giants are engineered to handle a wide range of sea conditions, making for a safe and enjoyable voyage.

Factors affecting cruise ship stability

While cruise ships are designed to be stable in various sea conditions, there are several factors that can impact their stability. Understanding these factors can help us grasp the complexities involved in ensuring the safety and comfort of passengers and crew onboard.

1. Weather conditions: The weather has a significant influence on cruise ship stability. High winds, storms, and rough seas can create large waves and swells that can potentially affect the ship’s stability. Cruise lines monitor weather patterns closely and may alter itineraries or change course to avoid severe weather.

2. Wave height: The magnitude and frequency of waves play a crucial role in cruise ship stability. Large waves can exert substantial forces on the ship’s structure, causing it to roll or pitch. However, modern cruise ships are designed to handle waves of varying heights, including those encountered during typical sea conditions.

3. Ship’s size and shape: The size and shape of the ship can impact stability. Larger ships tend to have increased stability due to their larger mass and wider hulls. Additionally, ships with a higher superstructure may be more affected by wind forces, potentially leading to increased rolling.

4. Passenger and cargo distribution: The distribution of passengers and cargo onboard the ship can affect stability, particularly in relation to weight distribution. Cruise ships carefully manage the loading process, ensuring an even distribution of weight to maintain balance.

5. Trim and list: Trim refers to the balance of the ship from bow to stern, while list refers to the balance from port to starboard. Maintaining proper trim and list is essential for optimal stability. Ballast tanks are utilized to adjust the ship’s trim, compensating for changes in weight distribution during the voyage.

6. Operating speed: The speed at which the ship is traveling can impact stability. High speeds can increase the forces exerted on the ship by waves, potentially affecting stability. Cruise ships typically adjust their speed based on prevailing sea conditions to ensure optimal stability and passenger comfort.

7. Environmental conditions: Factors such as currents and tides can also affect cruise ship stability. Strong currents or restricted waterways can influence a ship’s maneuverability, requiring careful navigation to maintain stability.

By considering these factors, cruise ship operators can make informed decisions to ensure the safety and stability of their vessels. Modern technologies and advanced navigation systems enable them to navigate through various conditions while prioritizing passenger safety.

Wave height and its impact on cruise ship stability

Wave height is a critical factor when it comes to cruise ship stability. Waves are formed due to wind, ocean currents, and various other factors. They can vary in size depending on environmental conditions and can have a significant impact on the ship’s stability.

1. Influence on ship motion: The height of waves directly affects the motion of the ship. When encountering larger waves, a cruise ship may experience rolling and pitching movements. Roll refers to the side-to-side motion of the ship, while pitch refers to the movement of the ship’s bow and stern in an up-and-down motion. While moderate rolling and pitching are generally well tolerated by modern cruise ships, excessively large waves can pose a challenge to stability.

2. Structural considerations: Large waves exert considerable forces on the ship’s structure. Cruise ships are built to withstand these forces through robust construction and design features specifically engineered to improve stability. The hull design, the positioning of bulkheads and compartments, and the strength of the materials used all contribute to the ship’s ability to handle big waves.

3. Stabilizer systems: Many modern cruise ships are equipped with stabilizer systems. These are retractable fins or wings located beneath the waterline on either side of the ship. Stabilizers counteract the rolling motion caused by waves by generating forces that act in the opposite direction. They help to minimize side-to-side movement, improving passenger comfort and maintaining stability even in rough seas.

4. Operational adjustments: Cruise ship captains and crews are trained to navigate through different wave conditions. They have the knowledge and experience to adapt the ship’s speed, course, and operation in response to wave height. Adjusting the ship’s speed or changing the direction of the ship’s course can help minimize the impact of larger waves on stability.

Although cruise ships are designed to handle a wide range of wave heights, there are limits to what they can safely endure. Extreme weather conditions can generate unusually large waves, referred to as rogue waves, that can exceed the typical range anticipated during the ship’s design. In such cases, cruise lines rely on advanced weather monitoring systems and navigation technologies to avoid areas prone to these extreme wave conditions.

Overall, cruise ship stability is carefully considered during the design and construction process. Through a combination of structural design, advanced technologies, and the expertise of the crew, cruise ships are built to handle various wave heights and ensure a safe and comfortable voyage for all passengers.

Design features that help cruise ships handle big waves

When it comes to navigating through big waves, cruise ships are equipped with a range of design features that enhance their ability to maintain stability and ensure the safety and comfort of passengers and crew. These design elements are carefully integrated into the construction of the ship, taking into account the expected operating conditions and the forces exerted by large waves.

1. Hull design: Cruise ships feature a modern hull design that helps them withstand the forces of waves. The hull is typically wider and flatter, which improves stability by providing buoyancy and reducing the impact of rolling. Additionally, the shape of the hull is designed to minimize resistance and optimize the ship’s performance in challenging sea conditions.

2. Bulkheads and compartments: Cruise ships are divided into multiple watertight compartments and are equipped with bulkheads, which are vertical partitions installed throughout the ship. These structural elements help to maintain the integrity of the ship’s structure and prevent water from flooding the entire vessel in the event of damage caused by rough seas or other unforeseen circumstances.

3. Strengthened superstructure: The superstructure of a cruise ship is the upper portion of the ship that houses cabins, restaurants, entertainment venues, and other facilities. To improve stability, the superstructure is reinforced with high-strength materials and structural supports, reducing the risk of excessive rolling and swaying caused by wind and waves.

4. Stabilizer systems: Stabilizers are retractable fins or wings located beneath the waterline on either side of the ship. These systems can be extended during rough sea conditions to counteract the rolling motion caused by waves. By generating forces that oppose the natural rolling motion, stabilizers help reduce the impact of large waves and maintain stability, enhancing the comfort of passengers on board.

5. Advanced monitoring and navigation systems: Cruise ships are equipped with state-of-the-art monitoring and navigation technologies that provide real-time information about wave height, wind speed, and other relevant data. This allows the ship’s crew to make informed decisions regarding speed, course adjustments, and other operational measures to mitigate the effects of big waves and optimize stability.

6. Ballast systems: Cruise ships utilize ballast systems, including specially designed tanks, to adjust the ship’s weight distribution. By strategically filling or emptying these tanks with water, the ship’s trim and stability can be optimized, providing better control and handling in challenging sea conditions.

These design features work in concert to ensure that cruise ships can handle big waves and maintain stability. By utilizing advanced technology and incorporating robust construction techniques, cruise ships are well-equipped to provide a smooth and enjoyable experience for passengers, even in rough sea conditions.

Case studies of cruise ships encountering large waves

While cruise ships are designed to handle big waves, there have been instances where vessels have encountered exceptionally rough sea conditions. These case studies highlight the resilience of modern cruise ships and the measures taken to ensure the safety of passengers and crew.

1. Queen Elizabeth 2: In 1995, the Queen Elizabeth 2 (QE2) encountered a severe storm in the North Atlantic with waves reportedly reaching heights of 90 feet. Despite the tumultuous sea conditions, the ship successfully weathered the storm without sustaining any major damage or injuries to passengers or crew. This incident showcased the robust design and stability of the QE2, which was renowned for its ability to handle rough seas.

2. Norwegian Breakaway: In early 2019, the Norwegian Breakaway, a large cruise ship sailing in the Atlantic Ocean, encountered a powerful winter storm with waves around 30 feet high. While the ship experienced significant rolling and pitching, it remained stable throughout the ordeal. The ship’s advanced stabilizer systems and knowledgeable crew played a crucial role in maintaining stability and ensuring the safety of all onboard.

3. Anthem of the Seas: In 2016, Royal Caribbean’s Anthem of the Seas encountered a severe storm off the coast of Cape Hatteras, with wind speeds exceeding 100 miles per hour and waves reaching heights of 30 feet. Despite the challenging conditions, the ship’s design features, including its strengthened superstructure and stabilizer systems, allowed it to withstand the storm and safely return to port. This incident prompted further safety protocols and increased weather monitoring measures for the cruise industry.

These case studies highlight the importance of robust design and advanced technologies in ensuring the resilience of cruise ships in the face of large waves. The meticulous planning and engineering that goes into creating these floating resorts are evident in their ability to navigate through challenging sea conditions while providing a safe and enjoyable experience for passengers.

It is important to note that cruise lines prioritize the safety of their passengers and crew above all else, and will adjust itineraries or alter course if severe weather or exceptionally large waves are anticipated in the ship’s intended path. The industry has stringent protocols in place to minimize risks and prevent accidents.

Safety measures and protocols for navigating rough seas

When it comes to navigating through rough seas, cruise lines have established robust safety measures and protocols to ensure the well-being of passengers and crew. These precautions are designed to mitigate the risks associated with challenging sea conditions and enhance the overall safety of the voyage.

1. Weather monitoring and communication: Cruise ships have sophisticated weather monitoring systems that track weather patterns in real-time. This enables the ship’s crew to anticipate and plan for adverse weather conditions. Additionally, constant communication with onshore meteorological services allows for up-to-date weather forecasts, helping the ship’s captain make informed decisions regarding the ship’s route and speed adjustments.

2. Crew training and emergency procedures: Cruise ship crew members undergo rigorous training in emergency procedures and safety protocols. This includes drills and simulations to prepare them for various scenarios, including rough sea conditions. The crew is equipped with the necessary skills to handle challenging situations, ensuring passenger safety and minimizing potential risks.

3. Stabilizer systems: As mentioned earlier, modern cruise ships are equipped with stabilizer systems that help reduce the rolling motion caused by waves. These systems can be deployed to counteract the effects of rough seas, enhancing the comfort and stability of the ship.

4. Navigation adjustments: The ship’s captain and navigation officers continuously evaluate sea conditions and adjust the ship’s speed, course, and route when necessary. This allows for optimal maneuverability and ensures the ship avoids areas of severe weather or exceptionally large waves.

5. Passenger safety briefings: Prior to setting sail, passengers are required to attend a mandatory safety briefing. During this briefing, important safety information is provided, including instructions on how to respond to emergencies and locate life jackets and evacuation routes. These briefings empower passengers to take an active role in their personal safety while onboard the ship.

6. Enhanced ship construction: Cruise ships are built to stringent safety standards, with reinforced structures and modern materials that enhance their ability to handle rough seas. These design features, such as watertight compartments and strengthened superstructures, provide additional safety measures in case of unexpected events or extreme weather conditions.

7. Regular maintenance and inspections: Cruise ships undergo routine maintenance checks and inspections to ensure that all systems, including navigational equipment and safety features, are functioning properly. This proactive approach helps identify and address any potential issues that could compromise the ship’s safety during rough sea conditions.

By implementing these safety measures and protocols, cruise lines prioritize the well-being of their passengers and crew. The combination of advanced technology, crew training, and meticulous planning helps to mitigate risks and ensure a safe and enjoyable voyage, even in challenging sea conditions.

Cruise ships are marvels of modern engineering, designed to provide a luxurious and enjoyable experience while navigating the vast oceans. Understanding how these colossal vessels handle rough seas and big waves is essential for all who embark on a cruise adventure.

Through meticulous design, advanced technology, and rigorous safety protocols, cruise ships are built to maintain stability and ensure passenger safety in a wide range of sea conditions.

Cruise ship arrives in NYC port with 44-foot dead endangered whale caught on its bow

Updated on: May 9, 2024 / 11:41 AM EDT / CBS/AP

A cruise ship sailed into a New York City port with a 44-foot dead whale across its bow, marine authorities said.

The whale, identified as an endangered sei whale , was caught on the ship's bow when it arrived at the Port of Brooklyn on Saturday, National Oceanic and Atmospheric Administration fisheries spokesperson Andrea Gomez said. A necropsy conducted later confirmed the whale's species and determined that the creature was a mature female, said the Atlantic Marine Conservation Society, a nonprofit organization that conducted the exam on an marine mammal.

A spokesperson for MSC Cruises said the whale was on the MSC Meraviglia, which docked at Brooklyn before sailing to ports in New England and Canada.

"We immediately notified the relevant authorities, who are now conducting an examination of the whale," officials with the cruise line said in a statement.

"We are deeply saddened by the loss of any marine life," the officials said, adding that the Geneva-based MSC Cruises follows all regulations designed to protect whales, such as altering itineraries in certain regions to avoid hitting the animals .

The dead whale was relocated to Sandy Hook, New Jersey, and towed to shore there to allow for better access to equipment and to conduct a necropsy, Gomez said.

The necropsy, an autopsy on an animal, was conducted on Tuesday, Gomez said. Samples collected from the whale will help biologists determine whether it was already dead when it was struck by the ship, she said.

Basic results of that exam showed evidence of tissue trauma in the area of the whale's right shoulder blade and a fractured right flipper, said the Atlantic Marine Conservation Society. In a post shared Wednesday to its Facebook page, the organization also said those tests revealed the whale's gastrointestinal tract was "full of food." Samples of its organs will undergo toxicology reviews and analyses to identify any potential tissue diseases.

"The tissue and bone samples collected will help biologists determine if the vessel interaction occurred pre or post mortem," said the conservation society.

Sei whales are typically observed in deeper waters far from the coastline, Gomez said. They are one of the largest whale species and are internationally protected.

According to the New York Department of Environmental Conservation , sei whales eat 2,000 pounds of fish and plankton per day. They can grow up to 60 feet long, weigh as much as 50 tons and live on average between 50-70 years.

The incident marks the latest endangered whale to be found dead along the East Coast.  Last month, federal authorities said a North Atlantic right whale that was found floating 50 miles offshore east of Virginia Beach, Virginia, was killed in a collision with a ship .

In March, NOAA said the first  North Atlantic right whale  baby born this season had  died after being hit by a vessel .

Environmental groups have called for tighter regulations on commercial fishing and shipping to try to save the whales.

In Massachusetts, there's a proposal to put  speed limits on fast ferries  to Cape Cod and the Islands to protect whales. The ferry companies counter that this would drastically reduce service, and say their captains have never seen a right whale on the job.

What are cruise ship pilots, and what do they do?

MSN has partnered with The Points Guy for our coverage of credit card products. MSN and The Points Guy may receive a commission from card issuers.

If you’ve sailed on a cruise ship of any size, you’ve probably seen pilot boats pull alongside the vessel, and you might have watched curiously as one or two people climbed onto the ship via a rope ladder. Have you ever wondered who these people are and what they do once they’re on board?

They are marine or ship pilots, experts on the waterways and ports you are entering or leaving. They come aboard to safely guide your cruise ship into and out of the harbor.

For cruise news, reviews and tips, sign up for TPG’s cruise newsletter .

To learn more, TPG chatted with two experts in the industry. Clayton L. “Clay” Diamond is the executive director-general counsel of the American Pilots’ Association, whose pilots are responsible for handling over 90% of the larger ocean vessels (cruise ships and cargo vessels) in international waters. We also spoke with Edouard Petitson, Norwegian Cruise Line’s port captain director. Based at Norwegian’s Miami headquarters, Petitson is responsible for many port-related matters, including pilotage.

Diamond and Petitson gave us the inside scoop on what happens once a cruise ship pilot is on board and how they interact with the captain and crew to help them safely navigate the ship into or out of port.

What does a cruise ship pilot do?

In ports in the U.S. and around the world, a pilot boards the ship 10 to 20 miles offshore via a pilot boat, which can be anywhere from 65 to 100 feet long. While on board, the pilot gives orders to the captain or helmsman regarding the best way to steer the ship to navigate the offshore channels and waterways until the cruise ship docks.

Marine pilots also pilot vessels from the dock to a “pilot boarding area,” where they transfer to the pilot boat. The pilotage can be as short as two to three hours or as long as eight to 10 hours.

Alaska has a different situation since cruise ships sail so close to the shoreline and icebergs during nearly all their transit. Vessels sailing in these waters will typically be under pilotage the entire time by using two pilots. This type of piloting arrangement is typical in places like Glacier Bay National Park and Preserve .

What qualifies a pilot over the ship’s captain to direct a ship into port?

“Marine pilots are the most highly trained mariners in the world,” says Diamond.

After many years of working in the maritime industry as a pilot apprentice and training in the waterways where they work, they are experts in their ports. Ship pilots must be able to chart the pilotage ground from memory, including the channel, landmarks, docks, buoys and any hazards to navigation.

“A pilot also has comprehensive knowledge of the local environments such as the hydrographic, wind and currents and tidal conditions,” Petitson adds.

Ship captains who sail into different ports around the world do not have the comprehensive knowledge and training that marine pilots do in one specific port. Essentially, marine pilots are maritime specialists in their port of expertise.

Does every port have a pilot?

There are only a handful of ports in the world where pilotage isn’t mandatory. In Miami and all U.S. ports, pilotage is compulsory and provided by local pilots for all inbound and outbound ships.

A state regulatory board oversees the number of pilots needed in each port. The board determines the number based on the port’s shipping and cruise traffic. The goal is to have enough pilots working to avoid delays.

What happens in foreign ports? Do all pilots have to speak English?

All pilots around the world are required to speak English.

“In certain destinations where English is not the primary language,” Petitson explains, “the pilot can communicate in their native language with other ships in the channel, traffic control and other pilots to eliminate possible misunderstanding, especially in an emergency situation.”

If the pilot and captain disagree, who has the final say?

The captain is always in charge of the vessel and the safety of the crew and passengers as the cruise ship is navigated into or out of port. If a disagreement arises, the captain will take over navigation until the situation is resolved.

Is the job dangerous?

If you’ve watched videos of pilots boarding ships by ladder, or have seen them jump from a moving ship to a pilot boat alongside, you’ve probably wondered how safe the process is.

Diamond tells us that the ladder has been deemed the safest way to board and disembark ships. The American Pilots’ Association focuses on safety and routinely works with the U.S. Coast Guard and the International Maritime Organization to improve and enhance the regulations for the ladders and pilot transfers. However, eight marine pilots have been killed since 2006.

How do you become a cruise ship pilot?

Individuals interested in becoming a ship pilot, or a pilot candidate, typically attend the United States Merchant Marine Academy in Kings Point, New York, or one of the six state maritime academies in the U.S. After completing the program, a pilot candidate will spend anywhere from eight to 14 years on ships to gain firsthand experience at sea.

Once they have earned their master’s credential, they can “master” a ship or become a captain. It’s usually during this time when a candidate enters a pilot apprenticeship program, which can take up to seven years to complete. Becoming fully licensed, where an individual can pilot the world’s largest ships, can take an additional four to five years.

Are there many female marine pilots?

No. The number of female pilots with an unlimited tonnage master’s credential is .01% overall. The number of female pilots in the APA is 4%-5%. Diamond tells us that the number is considerably better than what you’ll find in most other countries, but the APA would like it to be higher.

Bottom line

When you see that small pilot boat pull next to one of those giant cruise ships, you now know that the person coming on board to guide that ship safely into port has spent decades in education and training — and most of their career has been spent learning to expertly navigate one specific port. You can feel safer knowing that your captain can rely on a local expert to help guide the ship into or out of port.

The cruise ship was sailing towards the Brooklyn Cruise Terminal when authorities found the whale on its bow, the NYT reports. A boat later towed the whale to Sandy Hook Beach in New Jersey for a necropsy conducted by the conservation society.

Sei whales, a type of baleen whale that can be as big as 100,000 pounds and measure 40 to 60 feet, are considered endangered because the commercial whaling industry started targeting them in the 1960s — yes, that late — after exhausting stocks of blue and humpback whales, which became protected species.

From the mid-1960s to 1970s, whalers killed masses of sei whales until there are now only an estimated 57,000 to 65,000 out in the wild. It's estimated that the whaling industry, which went after sei whales for their meat and oil, culled 300,000 sei whales in the 19th and 20th centuries.

The gentle giants still face threats, including getting tangled in fishing gear and getting struck by sea vessels like the cruise ship that came to port on Saturday.

"When you’re out there, these animals might be there," he told the NYT . "We need to make people more aware about how to operate around these animals."

When is it too windy to tender?

By sparky791 , December 14, 2009 in Cayman Islands

Recommended Posts

Looking ahead, we come in to cayman islands on the 22nd. Forecast right now calls for 25mph winds out of the NNE. When is it too windy to tender? I know it happens every so often. We are scheduled to jet ski with fat fish and I also wonder how windy it has to be not to jet ski? Any help is appreciated. Thanks.

When the Captain deems it so.

All right smartee pants, think they meant how many miles per hour the wind.... I'd guess no more than 25-30 that's pretty windy. I can't see much higher than that working in your favor

Thanks for the legitimate response. They are talking 25+mph, so I think we could be in trouble. But what the heck we will still be in Carribean.

drew sailbum

It is a combination of wind speed and direction that matters.

George Town is on the western end of the island. Winds from the NE, ENE, E, ESE, or SE generally provide well sheltered conditions and relatively calm seas of making the transfers on and off the tenders.

Winds of 25mph from the NNE may, (just maybe, possibly, might) provide enough fetch for the waves to build up and cause problems with transfers.

If it is too rough in George Town, a wind from the NNE should provide excellent shelter and calm seas for operations at the alternate site at Spotts. Remember that the Spotts dock can only handle passengers from up to 3 normal size ships.

Thanks for the help. Latest weather report from caymanweather.com does not sound good. Three previous days up until we arrive from the Legend on the 22nd are calling for rough waves 4-6 feet. They have already issued a small craft advisory for the 19,20, and 21st.

Looks like our fat fish tour on jet skis will be cancelled. Anyone have suggestions for alternative activity for six people if we still can get in to Cayman Islands but not jet ski?

Sargent_Schultz

I wouldn't worry about it - won't do any good, anyway.

If you can tender...

The ship will cancel their water related tours before private operators do. If the ship does start canceling tours, don't assume private tours are doing the same.

There could still be snorkeling in sheltered areas. I've done that when other tours have canceled.

Do they ever substitute another port? We are due there 12/24 and it is our only non-US port.

We missed GC on our last cruise on the Legend.

The seas did not seem rough.

We did not substitute another port, we had an extra sea day.
