Your 199 GT tugboat is on a 675 mile coastwise voyage. What percentage of the deck crew must be Able Bodied Seamen?

Correct Answer: Option D — 65%

Under 46 CFR 15.605, for vessels of at least 100 gross tons engaged in a voyage of more than 600 miles, at least 65% of the deck crew must be certificated as Able Seamen. This regulation ensures a baseline of professional competency for the safe navigation of vessels on longer coastwise transits.
