If there are not enough lifeboats for everyone on board, then inflatable or rigid liferafts must accommodate the remaining 25% of passengers and crew. However, as we have seen, the IMO only requires a cruise ship to have enough lifeboats to accommodate 75% of its total capacity. Yes, cruise ship lifeboats are equipped with inboard diesel engines to provide self-powered propulsion. Having independent powered engines allows lifeboats to rapidly move away and maneuver independently from the cruise ship after being launched. Usually, boats are spaced evenly apart from each other along the length of the deck. On larger ships, lifeboats may be located on multiple available outer decks to provide capacity for more passengers.
What's the typical capacity of cruise ship lifeboats?
Due to their small storage footprint, inflatable rafts maximize survival craft capacity on board cruise ships. Now that we understand the importance of lifeboats and their usage in emergency situations, let’s explore the maintenance and inspections required to keep these vessels in optimal condition. Now that we have explored the types of lifeboats, let’s understand the safety features and equipment that make these vessels reliable and secure in emergency situations. By adhering to these international regulations, cruise ship operators demonstrate their commitment to passenger safety and emergency preparedness.
The Sinking Of The Titanic Led To Changes
Life Boat Launching will normally take longer and have a higher risk of failing due to a human factor. The Life Boats don’t have inflation system failures but the Inflatable Life rafts do. In addition to the regular inspections, the IMO has also recently amended the requirements for periodic servicing of life-saving appliances. Lifeboats, while crucial for emergencies, are also designed to sustain lives in potentially prolonged rescue scenarios. They come equipped with canopies to protect evacuees from the elements, be it scorching sun, rain, or high waves. These canopies, just like those on hard-shelled lifeboats, have clear patches or windows to allow for visibility.
How Big Are Lifeboats On Cruise Ships
This ensures that all aspects of the lifeboats, including the hull, propulsion systems, and safety features, are thoroughly inspected and serviced. Continuous monitoring, evaluation, and improvement of lifeboat configurations are necessary to adapt to evolving challenges and provide an optimal safety environment for all those on board. SOLAS also specifies the equipment and features that lifeboats must possess.

Liferafts
Partial coverage leaves the risk of some passengers being left behind if total evacuation is needed. Lifeboats are hard-shell boats with enclosed cabins that can be launched and operated independently of the ship. Crew may have to use slides to reach them, rather than just stepping onboard them from the ship’s deck. If Cruise Lines thought that bad weather may cause a ship problems, they would avoid the area or cancel the cruise, rather than risk the passengers or ship coming to harm.

The equipment includes everything needed to survive at sea while awaiting further assistance, including water, food rations, and numerous other items. Ships engaged in International Voyages must have partially or totally enclosed Life Boats. That means 100% Ridged or Inflatable Liferafts for at least 25 % of the people on board. Water weights are used in lifeboat testing during the production process to simulate the weight of passengers at different locations throughout the vessel. These water weights have remote pumps that fill and empty them with water. During the testing phase, they are positioned throughout the lifeboat to collect data on how the craft would manage passenger weight in various settings and circumstances.
Introduction of SOLAS (Safety Of Life At Sea)
During the Age of Sail, the ship's boats were used as lifeboats in case of emergency. The Royal Caribbean CRW55 mega lifeboats are 16.7m by 5.6m and hold 370 persons. The lifeboats might be partially or completely hidden behind panels or glass on some ships. Here’s an interesting time-lapse video of a 150-capacity lifeboat being loaded and released with 150 people (crew members) as part of a periodic capacity test.
In addition to the main drive engine, lifeboats also have a smaller generator engine. This provides power for electrical systems like radios, lighting, ventilation fans, and water pumps. You can identify lifeboat locations on a cruise ship by color-coding and numbering.
Why Didn’t Titanic Have Enough Lifeboats?
Saying that the larger Royal Caribbean 370 capacity lifeboats do have a water closet. The largest lifeboats, like those which were unfortunately destroyed on Costa Smeralda when it collided with a crane, can hold up to 440 passengers. Though more capacity is always better, cruise lines must find a reasonable balance across safety, regulations, costs, and customer experience. But if the worst happens, cruise lines work hard to ensure they have life-saving capacity and procedures to maximize lives saved. Lifeboat food supplies provide critical nourishment during an emergency evacuation at sea when quick rescue is not guaranteed. Lifeboats are positioned on the ship’s outer port and starboard sides for maximum launching stability.
The shortage of lifeboats was not due to the lack of space, she had actually been designed to accommodate up to 64 lifeboats. It is a well-known fact that Titanic didn’t hold enough lifeboats to hold all of the passengers onboard. The drill must take place within 24 hours of the ship leaving its first port and is also mandatory under CLIA’s policy.
Tradeoffs exist between comforts and saving space for people in life-or-death evacuations. These SOLAS lifeboat requirements provide an important emergency evacuation minimum for the massive populations onboard cruise ships. But as we’ll see next, some industry experts argue even more capacity is needed. For example, Royal Caribbean’s lifeboats have a capacity of 155 to 370 people.
This process often includes cleaning, lubricating, and adjusting the various parts of the lifeboat to ensure proper functioning. During the manufacturing process, lifeboats are tested using water weights, which can mimic the weight of passengers in various spots around the vessel. They're placed in various spots in the lifeboat throughout the testing period to gather data on how the watercraft would handle passenger weight in various locations and scenarios. It also works because it keeps the lifeboats high enough out of the water that they won't be in the way when the ship docks and most likely won't be affected by rough waves. On the flip side, it keeps them low enough that they don't have to be lowered the entire height of the ship (plus, no one wants a lifeboat view from the lido pool or their upper-deck suite).
Norwegian weather was reported at the time as having wind gusts up to 43 mph and waves of over 26 feet. She sailed from the northern city of Tromso, heading for Stavanger in southern Norway, but the ship began struggling with engine failure. She started to list dangerously, took in water, and was in danger of being blown ashore.
With the combined numbers of passengers and crew, the capacity of today’s modern cruise ships are often three or four times greater than that of the Titanic. Modern cruise ship lifeboats reflect cutting-edge marine technology, focusing on increased capacity, enhanced safety features, and superior maneuverability. These vessels, although compact, are designed to comfortably accommodate a large number of passengers and ensure their survival during the precarious journey away from a distressed ship. The selection of lifeboats on a cruise ship depends on various factors, including the ship’s size, capacity, and specific regulatory requirements. Each type of lifeboat is designed to meet specific safety standards and provide a means of escape and survival in emergencies. Passenger capacity, vessel size and type, risk assessment, and crew training are essential factors that impact the number and arrangement of lifeboats on a cruise ship.
