- For maximum performance With our electrically-powered Sail-Drive we offer a space-saving robust and high-performance drive system. The Sail-Drive has a shaft diameter of Ø 25mm and 1:10 taper shank for common types of propeller. Once you have fitted the corresponding three-blade propeller, you have access to power that is comparable to that of an onboard diesel engine. - Controllable The practical single-lever control provides non-stepped motor-speed regulation in forwards or reverse - and the high-performance electrical regulating system works with virtually no energy loss. - Low-noise The electric motor runs quietly and with very little vibration. - Easy to install The Sail-Drive ist supplied with a base plate for laminating onto the hull of he vessel. This keeps installation tasks down to a bare minimum. The Sail-Drive is also applied with an adapter plate for direct bolt-attachment to existing fixed "Volvo" and "Yanmar" bases.
