Harken UniPower Radial
The UniPower is a single-speed winch that combines the advantages of a low-profile manual winch with the power of a 12-, 24-, or 48-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") below the winch base—a critical feature for small boats where space under the cabintop is very limited.
