Survival craft required on a steel small passenger vessel operating in cold water must __________.

Correct Answer: Option D — have sufficient capacity for all persons on board the vessel in ocean service.

Per 46 CFR Subchapter T, steel small passenger vessels in ocean service must provide survival craft capacity for 100% of all persons on board. This ensures that in the event of a total vessel abandonment, every passenger and crew member has a designated place in a survival craft.
