With marine electric winches the engineering is below the deck and powered by the ships batteries, whereas with the Powerwincher the engineering and electrical is contained within the winch handle. The Powerwincher is relatively compact compared to the underdeck of marine electric winches.
In addition, the Powerwincher can be taken from boat to boat, unlike marine electric winches that are fixed and can only be used on one Sailboat and in one place on the Sailboat.
Marine Electric Winches are expensive and not always forgiving so can be damaging to the gear on your boat.
Powerwincher will do anything you can do with a manual winch handle, but better, faster and for longer than you can wind!
The Powerwincher electric winch handle is becoming very popular with yachtsman and sailors due to its portability and comparatively lower cost.
