Question 1 of 27070

According to uninspected vessel regulations, what is the minimum number of portable fire extinguishers required on board a 45-foot motorboat built in 2017 having a fixed fire system on board?

🔍 Key Concepts

• 46 CFR 25.30 portable fire extinguisher requirements for uninspected motorboats • Length category for a 40 feet to less than 65 feet motorboat and how many extinguishers are required with and without a fixed system • Conversion between older B-I / B-II ratings and newer 5-B / 20-B style ratings

💭 Think About

• First, find the table in 46 CFR 25.30 that applies to uninspected motorboats and identify the base number and type of extinguishers required for a 45-foot vessel without a fixed system. • Next, see what adjustment the regulations allow when a fixed fire extinguishing system is installed in the machinery space—how many portable extinguishers can be deducted? • Then, convert the required B-I/B-II equivalents into 5-B units, and compare that total to the answer choices.

✅ Before You Answer

• Confirm you are looking at the row for motorboats 40 feet or more but less than 65 feet in the correct table. • Verify exactly how a fixed fire extinguishing system changes the number and size of required portable extinguishers for that length. • Double-check how many 5-B units equal one B-II extinguisher before matching your total to the options.
