On a steel passenger vessel operating in cold water, the survival craft must have capacity for all persons on board.

• A. 75 percent of persons on board
• B. All persons on board
• C. 50 percent of persons on board
• D. 25 percent of persons on board

Answer: (B)

The main concept here is that survival craft capacity must be able to carry every person on board. For a steel passenger vessel, especially in cold water, regulations require that the lifeboats and liferafts have enough capacity to accommodate the maximum number of people on board, so no one is left without a means to abandon ship and survive. This is about ensuring complete, immediate evacuation capability in an emergency, not just a portion of the crew or passengers.

That’s why all persons on board is the correct answer. If survival craft could only hold a fraction, some people would be left without a lifeboat or liferaft, which is not acceptable under the safety standards for passenger vessels. The other options propose partial coverage, which fails to meet the required safety provision.
