Winches > Hydraulic

Hydraulic winches use a central power source to drive all of the powered winches on larger cruising boats. The same power source can be used for other functions on the boat such as backstays, vangs, furling, or centerboards.

All Harken hydraulic winches, including the smallest sizes, operate in two speeds both when using the hydraulic motor and when cranking by hand. This two-speed ability in the powered mode is unusual in small winches and is of significance for speed of trimming and hoisting sails.

Hydraulic winches size B56 and larger are available in both two- and three-speed models. The third speed is useful where high line speed at light load is desirable. The B1110 and B1120 are three-speed winches. The B1140 winch is a three-speed but also has an additional backwind speed. Backwind is useful on very large yachts for relieving the load on the winch before a sheet is released.

All hydraulic motors are mounted vertically and all hydraulic fittings are industry standard for ease of service and compatibility with other components.

Use for:

  • Halyards
  • Sheets

    Note: unlike competitors' winches, all Harken hydraulic winches have two speeds and drive through the transmission to increase power or speed without additional battery drain.

    Ordering information:

    Each winch requires two switches and a control box. See this page. The B1140 requires an additional switch for the backwind. Three-speed winches from 56s are available by special order. Specify winch drum material by adding A (aluminium), B (polished bronze), or C (chromed bronze) to part number. Polished bronze by special order only.
