A vessel of not more than 65 feet in length must have a collision bulkhead if it carries more than __________.

Correct Answer: Option A — 49 passengers

46 CFR 179.310 requires a collision bulkhead for small passenger vessels not exceeding 65 feet in length if they carry more than 49 passengers. This structural requirement ensures vessel integrity and buoyancy in the event of a forward collision, providing a critical safety barrier for high-density passenger operations.
