Winches > Powered

Powered winches offer great convenience to cruising sailors. They allow small crews to handle high loads on large boats. Sheets, halyards, and major control lines are all well suited to the use of powered winches. Harken offers both electric and hydraulic self-tailing winches in a wide range of sizes and configurations.

Every Harken powered winch, including the smaller sizes, operates in two speeds in both powered and manual modes. Two speeds in power mode on smaller winches is unusual. It ensures high line speeds under low load, while retaining higher torque in low gear. Powered winches from the B56 may be ordered with three speeds for very high line speeds under low loads.

All Harken powered winches operate with simple waterproof switches and reliable, easy-to-service, electric controls. The crew may select either first or second gear depending on load.

Electric

Electric winches offer the convenience of powered winches in an easily installed system. Each winch is wired with two switches and a control box that mounts in a sheltered location below deck. Harken electric winches through the B980 are offered for either 12 or 24 volts. Larger winches use 24 volts.

Because all electric winches have their own easy-to-wire motor, they are generally less expensive to use when plans call for just a few powered winches. When many winches or other functions need to be powered, hydraulics, which use a central power source, should be considered.

Hydraulic

Many large cruising boats use hydraulics for windlasses, furling, centerboard lifts, vangs, and backstays. This power source may also be used to drive Harken hydraulic winches. Use of a central hydraulic power source reduces weight and noise because only one motor is required to drive the entire system. Harken offers hydraulic self-tailing winches, hydraulic power sources, and control systems that can drive winches and other accessories.

All hydraulic motors are mounted vertically. All hydraulic lines and motors use standard components so that winches are easy to service anywhere in the world.

Hydraulic Power Units

Harken offers four sizes of hydraulic power units, plus custom sizes for special applications. These are centrally positioned power units supplying hydraulic power to different functions on the boat—winches, furling, windlass, steering, centerboards, and davits.

Power units are driven by either 12- or 24-volt electric motors. All of the hydraulic connections are made with standard high-performance hydraulic fittings. These systems are very simple and use commonly available hydraulic components so that service is possible worldwide. The Hydro 6 and 8 use two motors. A manual switch allows selection of one or both motors at any time. Two motors allow extra power and provide a backup power source.

Every power source is tailored to its specific use. Pressure and flow are adjustable and each valve can be fitted with separate pressure and flow valves. Custom power units are available for large boats.

Electric winches have an attached motor. Installation involves wiring the winch, installing two switches, and mounting a control box below decks
All Harken electric winches have two speeds and drive through the transmission to increase power or speed without additional battery drain

B74.2STHC hydraulic winch features large-diameter bearings and efficient self-tailing mechanism

BRS104/P switch. Switches are mounted near winch and can be positioned for hand and/or foot operation

1. Vertical or Horizontal Mounts
Motors on most electric winches through the B980 can be mounted either vertically or horizontally to match your installation requirements.

2. Easily Reverts to Manual Power
Winches revert to manual operation when a locking handle is inserted so the boat can be raced or cruised without use of the powered system. Insertion of the winch handle automatically disconnects the powered system.

3. Various Finishes Available
Powered winches are self-tailing with chromed-bronze or aluminum drums. Polished-bronze drums are available by special order. The B1110 and larger have stainless steel drums.
