california-based startup boundary layer technologies has launched an electric hydrofoil ferry concept that promises twice the speed and range of existing electric ferries. called ‘electra’, the boat cruises at a speed of 40 knots and has a range of up to 100 nautical miles thanks to a podded propulsion system at the back and two lifting foils that reduce drag in the water.
the batteries that power electra have a capacity of 9000kWH and can be fully charged in less than three hours (based on a 2400kW charging system). boundary layer technologies says the battery-powered system significantly reduces cabin noise by up to 20db compared to conventional ferries. the 150 passenger ferry also promises a smooth ride even in choppy water.
not only better for the environment, electra’s electric system is lighter on the pocket too. the marine tech company estimates that the electra ferry offers reductions in operating expenses of up to 35% compared to fossil fuel burning fast ferry alternatives.
boundary layer technologies has already developed the hydrofoil and control systems required for electra, and plans to have the first vessels in operation by the first quarter of 2024 in regions such as the united states, scandinavia, and the mediterranean.
The proprietary technology at the core of Electra is our high efficiency hydrofoil design. This reduces the drag of the vessel by half, allowing for increased range, ride quality and zero wake.
