I have been receiving questions regarding regulations governing the heating systems on passenger vessels. These regulations are contained in 46 CFR 25.45 Cooking, Heating and Lighting Systems; part 25.45-1 describes the heating systems that it is legal to use of vessels carrying passengers for hire. This regulation states:
No fuel may be used in any heating or lighting system on any vessel carrying passengers for hire without the approval of Commandant (G-MSE), except— (1)Alcohol, solid, (2) Alcohol, liquid, combustible, (3) Fuel oil, No. 1, No. 2, or No. 3, (4) Kerosene, (5) Wood or, (6) Coal.
According to this regulation it is not legal to use a propane heating system on a passenger vessel without the expressed permission of the Commandant of the Coast Guard.
