The UniPower from Harken is a single-speed winch that combines the advantages of a low-profile manual winch with the power of a 12- or 24-volt, low-amp-draw motor. What makes it unique is that the motor is partially imbedded inside the drum, so that it extends only 105 mm (4 1/8 inches) below the winch base—a critical feature for small boats where space under the cabin top is limited. Composite roller bearings reduce friction under load and don’t require lubrication. The stripper arm and load-carrying gears are 17-4PH stainless steel for strength and durability.
Winches include a waterproof switch and a one-speed control box with built-in current controller to protect hardware by electronically limiting the winch’s maximum pull to 1984 lbs (900 kg).
