RS Marine Group and ePropulsion announce partnership to power the Cheetah R630

RS Marine Group has announced the collaboration with ePropulson’s X Series electric outboards to power the group’s Cheetah R630 EV-ready RIB, which will be showcased at the RYA Dinghy & Watersports Show, taking place at Farnborough International on 24-25 Feb.

ePropulsion has confirmed it will supply its award-winning X Series electric outboard motors for the Cheetah R630, comprising either the X20 or X40, offering 20kW or 40kW of power respectively. These options cater to different needs and preferences, providing efficient and environmentally friendly propulsion.

The 6.3 metre Cheetah R630 has been designed, in conjunction with RS Electric Boats, with efficiency in mind. It features a cathedral hull, pushing less water and getting on the plane effortlessly at lower speeds than a normal RIB of its size. It is also equipped with either 22kWh or 43kWh battery packs, ensuring reliable and extended cruising ranges suitable for various adventures on the water.

“We’re delivering on our strategy to provide EV-ready craft,” says Jon Partridge, RS Marine Group CEO. “The marine sector has definitely woken up to the fact that we need to make a decisive change and we are excited to be working with ePropulsion as our power supplier.

“Our partnership began with the RS21, which comes with a built in 1kw ePropulsion unit. This early collaboration helped form the idea for RS Electric Boats”.

“We are delighted that RS Marine Group has chosen ePropulsion’s X-Series Outboard Motors for their new Cheetah R630,” says Steve Bruce, ePropulsion Global OEM Director. “The X-Series motors are a testament to our commitment to advancing technology in electric marine propulsion.”

“Our partnership extends beyond providing advanced, eco-friendly motors; we are also designing a custom battery specifically for the R630 hull. This unique combination enhances the R630’s standing as a pinnacle of sustainable boating innovation, redefining industry standards in efficiency and performance.”

“During testing, the X-40 demonstrated remarkable results, affirming its alignment with the R630’s innovative design. The synergy between the motors and the vessel showcased outstanding operational characteristics, further enhancing the R630’s appeal as a leader in its class,” concludes Bruce.
