The painter on a rigid life raft must have a length sufficient to reach the highest waterline plus an additional __________.

Correct Answer: Option D — 20 meters (66 feet)

Per 46 CFR 160.151, the painter line on a life raft must be of sufficient length to reach the lightest seagoing condition waterline plus an additional 20 meters (66 feet). This length ensures the raft can be safely deployed and inflated from the embarkation deck without being pulled prematurely from the vessel.
