A recreational vessel of 350 gross tons and more than 65 feet in length does NOT have a fixed fire extinguishing system in the machinery space. Which additional fire extinguishing equipment is required in the machinery space beyond the portable extinguishers mandated by gross tonnage?

Question

Accepted Answer

A. One 160-B semi-portable fire extinguishing system permanently attached to a bulkhead or deck — 33 CFR §175.320(b)(2)(ii) requires that on recreational vessels of more than 300 gross tons, either one 160-B semi-portable fire extinguishing system must be fitted or a fixed fire extinguishing system must be fitted in the machinery space. Since no fixed system is installed, the 160-B semi-portable is required. Per §175.320(b)(3), its frame must be welded or otherwise permanently attached to a bulkhead or deck.

Answer

B. Two 20-B portable extinguishers regardless of engine horsepower

Answer

C. One 20-B extinguisher per 1,000 BHP only; no semi-portable system is required below 500 gross tons

Answer

D. A fixed CO2 system designed per 46 CFR part 76, subpart 76.15, is mandatory at this tonnage
