I think it's not possible to fit enough batteries by weight to scale this. Consider the Voskhod boat which at 28 tons and 60 km/h has to have ~800kW engine. To have any useful range the battery mass and charge time would be prohibitive. Turbodiesel and/or gas turbine work just fine though. https://en.wikipedia.org/wiki/Voskhod_(hydrofoil) https://en.wikipedia.org/wiki/Voskhod_(hydrofoil)
