How many B-II fire extinguishers must be in the machinery space of a 75-foot long fishing vessel propelled by engines with 2000 brake horsepower?

Correct Answer: Option A — 2

Per 46 CFR Table 28.160 for commercial fishing industry vessels, machinery spaces with propulsion power between 1000 and 3000 brake horsepower require a minimum of two B-II portable fire extinguishers, regardless of vessel length, provided fixed systems are not the sole factor considered.
