The expression “ second hand ” means, with respect to a fishing boat, the mate or person next to the skipper in authority or command on board the boat.

The expression “ voyage ” shall mean a fishing trip commencing with a departure from a port for the purpose of fishing, and ending with the first return to a port thereafter upon the conclusion of the trip, but a return due to distress only shall not be deemed to be a return, if it is followed by a resumption of the trip.
