ePropulsion UK has signed a deal to supply fully-integrated propulsion systems to RS Sailing.

The contract covers a bespoke mounting arrangement and integration of ePropulsion’s 1kW Spirit electric motor into a flush-fitting retractable electric drive system onboard the first 60 boats in RS Sailing’s RS21 keelboats.

“The main challenge was to create a brand-new plug-n-play system for one of the fastest growing classes of keel boat in the world,” explains Ricky Cole, head of technical development at ePropulsion UK. “Short lead times are standard for new racing classes, but we also had to create an out-of-the-box solution that can be used during the boatbuilding process or sent for retrofitting on boats anywhere in the world that are already being raced.”

The system has a new side-mounted throttle arrangement with a removable handle.

The top bracket motor mount has been redesigned and CNC machined from solid 6061 aluminium alloy with a hard-anodised coating.

Eliminating drag

A proximity switch has also been added which only allows the motor to run when it is locked down in the correct operating position.

Battery and motor information is displayed on a new high-contrast LCD screen

In addition, a new nylon mounting bracket with stainless steel fittings has been developed. When racing, the whole motor arrangement, is hauled-up into the stowed position with the outer hull plate flush with the rest of the hull, eliminating any unnecessary drag.

“The system works perfectly and is one of the easiest systems we fit on the boat, even when we are retrofitting on boats away from the factory,” said Alex Southon, RS Sailing’s CEO – design and technologies. “It’s silent, robust and really complements the overall quality of the RS21 package.”

The Spirit motor weighs 7kg and provides the equivalent thrust of a 3hp petrol outboard.
