A non-wood small passenger vessel certificated for a limited coastwise route operating in cold water is required to carry life floats with an aggregate capacity sufficient to accommodate what percentage of the total number of persons permitted on board?

Why D is correct

46 CFR §180.205(b) requires each vessel constructed of a material other than wood certificated to operate on a limited coastwise route in cold water to be provided with life floats of an aggregate capacity that will accommodate at least 100% of the total number of persons permitted on board. The 67% figure applies to wood vessels on limited coastwise routes in cold water under §180.205(a)(1).
