Initially, Fir had two tenders housed on the 02 aft deck, or rear boat deck. Gantry cranes were mounted to each side, and the winch was centered in the middle of the deck. Essentially the entire deck was consumed by the tenders and associated equipment. Meanwhile the forward 01 deck, was kept clear for Fir to hoist buoys aboard for repair.
For our purposes, a better arrangement would be to use the forward deck for tenders while keeping the rear deck open and unobstructed . To preserve Fir's integrity, the gantries will remain in place, but the operating equipment will be removed, and the tenders redistributed.
