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.

Admittedly it’s WAY easier to operate a motor boat than a sail boat, so depending on how you like to recreationally bleed your unlimited money I can see reasons for that choice.
But I fully agree that we’ve had renewable energy-based ships with unlimited range for millenia. The claim that “The aim was to demonstrate that zero-emission sea travel [is possible today]” broke my brain a little.

Sitting here reading about sail boats being easier to maneuver in harbors cause of bow thrusters, after having dealt with major prop walk just the other day in high winds while docking. The trick is keeping water moving past your rudder. Once your down to a knot or under things get dicey. Even with thrusters.

Hah. Your bar for “super rich” and mine may be in different places.
And you’re preaching to the choir, I’d much rather sail myself. But nerding out about the specifics aside, it’s very weird to leave it out of the renewable-powered sea travel conversation the way these guys are doing.

…and into the bottom of the ocean.

I don’t understand why sailboats have an advantage. What do they have for generating wind that the other boats don’t? All boats experience the same wind. Do the propeller+engine on a sailboat act as a generator when the boat moves with wind power?

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!
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.)

Sailboats can operate at lower power levels, because their displacement hull is efficient at low speeds. (Where a planeing hull needs higher speeds to get more efficient.) When I had solar electric sail boat, I could motor at 2 knots with no wind using only 500w of solar without touching the battery. I usually ran it at 3.5 knots if there was no wind, which gave me lots of range on battery for a full day on the water.
They also have the sail as a primary power source when there’s enough wind, so you don’t always need the electric motor. Sometimes, if the wind is strong enough, you can use the water turning the propeller to generate electricity to charge the battery. Or if the wind is light, you can use the motor to add more speed than sail alone, using less battery than using electric alone.
