If youve ever had the pleasure of sailing or racing aboard a boat equipped with Andersen winches, then you know you really can feel the difference when uncompromising quality is built in. These stainless-steel winches are smooth, quiet, efficient, and easy to use. They combine Andersens famous Power Rib drum surface, which generates horizontal friction, with a highly polished surface to minimize vertical friction, so the rope slides easily up the drum. The self-tailing system adjusts automatically to accommodate various rope diameters. The self-tailing arms are curved to give a fair lead, so friction is minimized. Pawls are made from unbreakable cold-pressed 316 stainless-steel bar. Lightweight stainless drums, combined with aluminum bronze internal construction, results in a winch that actually weighs the same or less than aluminum winches of similar size. Aluminum bronze base plates are twice as strong as standard bronze, giving a light, stiff and strong construction for increased winch efficiency. Thanks to the superb quality of materials used, winch service is required only every second year under normal use. 46ST Two Speed winch, 2.8:1 Gear Ratio 1st, 8.4:1 Gear Ratio 2nd, 15.5:1 Power Ratio 1st, 46.6:1 Power Ratio 2nd, 3-3/16" Drum Dia., 7-1/16" Base Dia., 8-1/16"H, 16 lb.
