Equipmake, a UK-based electrification specialist, has supplied an advanced drivetrain system for the world’s first electric flying boat.
Developed by the modern classic yacht design and build experts, Spirit Yachts, in collaboration with an advanced marine engineering company, BAR Technologies, the new SpiritBARTech35EF is claimed to be the first of its kind to have a fast-cruising range of 100 nautical miles (185 km).
This comes at a time when demand for pleasure craft that are both exciting and yet have a more responsible footprint continues to grow in line with developments in battery technology and the convenience of electric drives. Combining the luxury yacht design and construction of Spirit Yachts with the holistically designed eco-friendly vessel platforms of BAR Technologies, the SpiritBARTech35EF blends heritage and modernity to usher yachting into a new era.
Using BAR Technologies’ America’s Cup simulation and design expertise, the purpose-built 35-ft electric flying boat features a trio of active retractable foils to help minimize drag. The boat is constructed from a mix of titanium and cold-molded wood with a carbon fiber reinforced shell, a structure that weighs just a tonne.
For the project, Equipmake designed and developed a bespoke fully electric drivetrain featuring a specially adapted version of its lightweight, power-dense, high-performance HPM-400 motors, producing peak power of 80kW, complete with an integrated gearbox. The drivetrain also features Equipmake’s own HPI-450 IGBT inverter and a 120kWh custom battery pack.
Combined with the advanced e-drivetrain from Equipmake, the SpiritBARTech35EF has a top speed of 28 knots (52 km/h) and can achieve its total range at a speed of 22 knots (41 km/h).
Above the waterline, the yacht’s sleek visual appearance is in keeping with traditional, beautiful aesthetics through Spirit Yachts’ distinctive design and craftsmanship. The yacht seats six in an open cockpit configuration, which can be converted to a 2-seat spider configuration at will.
