Electric Boat Costs 40–50€ to Cross Baltic Sea, vs 750€ Refueling Gas Boat (cleantechnica.com)

While the much lower fuel cost has to be a bit of a shocker (we all know EVs are more efficient and cheaper to operate, but not 95% cheaper), the bigger surprise has to be how much more convenient the electric boat was in a certain key way. “We actually had range anxiety, but not for the Candela. The irony is that the photographer’s gasoline-powered chase boat had to refuel six times during the trip, while we only charged three times,” said Gustav Hasselskog.

213kWh feels like quite a lot of juice. Admittedly, I usually don't go at planing speeds.

I have an 80Ah lead-acid battery to power the electric trolling motor on my inflatable dinghy. That's 80A*12V = 0.96kWh. That gives me 5-10Nm range depending on speed. My dinghy would sink with 213kWh on board.

My 7 tonne sailboat uses ~2l/h of diesel at twice the speed. 213kWh of lead-acid would double the weight.

This says it uses the battery from a polestar. So it's not lead acid but lithium. And 79kWh.
