Pontos winches by Karver are based on epicyclic gear trains associated with automatic load detection technology. Depending on the choice of model this approach can offer either 3 times more power or 6 times more speed compared to all other winches on the market. The automatic four-speed gearing mechanism of the Power range provides additional winching power when you need it most. Changing gear is simple. When too much pressure builds up on the winch handle, just reverse the direction and the next gear is engaged. Once the line pressure is off, the winch reverts to the most suitable gearing for the next time you winch. The ultra-power gear reduces effort by more than 50% whilst doubling the torque meaning anyone can trim and fine-tune even the largest sails aboard. The drum is constructed in hard anodized aluminium, gears and clutch in 17.4 PH stainless steel and copper aluminium alloy and needle bearings in polyoxymethylene. All winches are self-tailing, enabling single handed sail trimming. All Pontos winches by Karver feature a 5 year warranty.
