Which of the following statements about life boats is correct?

Open lifeboats being mostly obsolete is correct because advancements in safety and lifeboat design have shifted preferences toward enclosed lifeboats for most modern vessels. Enclosed lifeboats provide enhanced protection from the elements, which is crucial during emergency evacuations. They offer better thermal insulation, reduce the risk of hypothermia, and can be launched in rough weather conditions, making them more reliable in emergencies.

While open lifeboats have historical significance and may still be found on some older vessels, they are less favored due to their limited protection and ability to maintain safety in adverse conditions. The development of improved technology has diminished the practicality of open lifeboats, leading to their reduced presence in contemporary maritime operations.

The other statements do not accurately reflect the current state of lifeboat technology or safety standards. For instance, not all lifeboats require no fuel; some types of lifeboats, particularly those that are motorized, do require fuel for operation. Enclosed lifeboats indeed offer several advantages, making them preferable for modern maritime safety protocols. Lastly, while open lifeboats existed at one time, referring to them as the newest technology is misleading, as it overlooks the significant advancements made in lifeboat safety.
