Always wanted to get a boat. The costs for fuel are insane. The costs for maintenance and marinas are insane. Setting aside maintenance and marinas . . . let's look at fuel. Where is the Elon Musk for yachts and pleasure boats? Nothing huge, 30, 40 footers, with a sleeper cabin etc, but no gas engine. Perhaps instead, one, (two?) Model S 85kWh battery packs and a Tesla motor or two Understanding how ridiculously inefficient boats are (in gas terms they get gallons per mile), I always wondered if anyone had done the math on whether Battery Electric Vessels were even technically feasible.
