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.

Interesting bit about the surplus wind! I hadn't thought of that, and didn't know that boats can have a dedicated hydro generator device. Thanks!

Super easy to retro fit to be able to pull it out the water when its a light wind too, great for anybody wanting to reduce using their main engine as a battery charger.

Solar is great on sail boats but often the sails block the sun when they are out so its difficult to get full utilisation. Something like a hydro generator works perfectly with a good sized solar install for a sail boat to cover at anchor and under sail.

Boats with electric motors don't need a dedicated generator, as the motor can act as a generator when you put it in neutral. (If properly configured.)
