Your vessel is equipped with totally enclosed lifeboats. Which of the following statements is correct should the boat be enveloped in flames?

Correct Answer: Option D — A pressurized air tank will provide approximately ten minutes of air for the survivors and the diesel engine.

Totally enclosed lifeboats are equipped with a compressed air system to support both the engine and occupants for a limited duration, typically ten minutes. This allows the craft to transit through fire-enveloped waters without drawing in toxic smoke or flames, protecting the integrity of the engine and crew.
