SailMaster

As the name indicates, this propulsion solution is specifically for sailyachts. The SailMaster asynchronous propulsion systems were developed for application with the standard saildrive propulsions from, for instance, Selva.

With a very low resistance, the systems are delivered with a capacity of 5 or 7.5 kW at 48 V. The standard delay in the saildrive causes the propeller to run relatively slowly: This allows for a larger propeller with increased thrust and efficiency, while also compensating for any transfer loss and minimising vibrations. Although the installation inside the vessel means there is some audible sound, it is nothing compared to the noise of a normal diesel engine.

Enjoy the peace…
