Main Winch: The main winch is a Dynacon, new in 1993. Hydraulically powered, this winch is controlled from a console station on the main deck and currently carries 9,600 ft. of 1/2" 3 X 19. There is a four-conductor slip ring and a capability of handling 6,000 ft. of .680 conductor cable.
Hydrographic Winches: Two hydro winches, Dynacon Model 8000A, are available for water-bottle sampling, light coring, dredging, plankton net, and CTD (conductivity, temperature, depth) work. One has 10,000 ft. of 1/4" 7 X 19 stainless wire rope, the other has 11,666 ft. of .322 diameter 3 conductor wire in 1996. An extra spool, interchangeable with either winch, is available.
Crane: TICO 150 marine crane. Lifting capacity 14,109 lbs. at 6'6" extension; 5,666 lbs. at 16'5" extension (4'5" over the side); and 1,433 lbs. at 41' extension (29' over the side).The crane is mounted amidships on the 01 deck.
