Equipmake, Spirit Yachts, BAR collaborate on world-first marine project

LinkedIn +

Spirit Yachts and BAR Technologies have collaborated with Equipmake on an electric flying boat with a cruising range of 100 nautical miles (115 miles).

The SpiritBARTech35EF luxury electric flying boat is 35ft in length, and was designed using BAR Technologies’  America’s Cup simulation and design expertise.

John Cooper, CEO, BAR Technologies said, “We firmly believe that the future of this sector will be defined by developments in the sustainability and efficiency of vessels.”

The result is a trio of active retractable foils to help minimise drag, and a hull constructed with a mix of titanium and cold-moulded wood with a carbon fibre reinforced shell, a structure that weighs just one ton.

For the project, Equipmake designed, developed, and manufactured a fully electric drivetrain, featuring a specially adapted version of its lightweight, power dense, high-performance HPM-400 motor.

The motor produces peak power of 80kW, complete with an integrated gearbox. The drivetrain also features Equipmake’s own HPI-450 IGBT inverter and a 120kWh battery pack.


The SpiritBARTech35EF has a top speed of 28 knots/32mph and can achieve its total range at a speed of 22 knots.

The project is the first time Equipmake has ventured into the electric marine market, which is estimated to be worth USD$16bn by 2031.

Our in-house developed electrification technology has many varied high-performance applications, from aerospace to automotive, and the SpiritBARTech35EF is the perfect showcase for how it can be applied to the rapidly growing electric marine market,” said Ian Foley, CEO, Equipmake.

Following the success of the project, Equipmake and BAR Technologies are exploring further opportunities to collaborat,e and increase the potential market for Equipmake’s products in BAR Technologies’ systems.
