Harken Alu. Radial Winch Unipower ST 900 12V 900UPWA12

The UniPower 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. Gears are 17-4PH stainless steel for strength and durability.
