You are onboard a 120 GT uninspected sea going tug which carries one Master and one Mate of Towing Vessels and four (4) seamen when underway. How many of the four seamen must have a rating as able seamen if the voyage is under 600 miles?

Correct Answer: Option C — 2

Per 46 CFR manning scales for uninspected seagoing towing vessels on voyages under 600 miles, at least 50 percent of the deck crew exclusive of officers must hold Able Seaman ratings, requiring two out of the four seamen to be qualified.
