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.
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.
