For pumping the bilges, a 54 foot long "T-Boat", which is not a ferry, but is certificated to carry 30 passengers, must be fitted with at least __________.

Correct Answer: Option D — either "A" or "B"

46 CFR 182.520 mandates bilge pumping requirements for small passenger vessels. For a vessel of this size, the regulation requires either one fixed power pump and one portable hand pump, or one fixed hand pump and one portable hand pump, ensuring redundancy in the event of flooding.
