Why Not An Electric Wakeboard Boat ?
Electric cars are starting to pop up. Everything from minimalist Zaps to sporty Tesla’s to Porsche conversions. With petrol now over $4/gallon in the
Why not electric boats?
I assume one major obstacle is the small issue of electricity and water not mixing so well. This can be worked out though. In fact, the Navy powers many of their boats with electricity without water problems. Of course they also have onboard nuclear reactors to generate electricity and I’m not sure we’re far enough along with that for consumer use. However, battery and motor technology has advanced enough to make this a viable alternative and I’m sure boat builders can design a system to keep the batteries and motor both dry and adequately ventilated.
But oy vey, the advantages…
The batteries and motor are overall lighter than the equivalent power and run-time of 30 gallons of petrol and a marine engine. An electrical drive system is also comprised of many smaller components that can more easily be distributed around a hull for optimal weight distribution. It’d be possible to produce a center weighted slalom tow boat without a mid engine. Everything would be below deck and could even be a bit more forward than venerable towboats such as the Nautique 196 resulting in an even smoother wake. This also leaves room for massive ballasting to change the boats characteristics for wakeboarding or surfing.
Yes, the holy grail of perfect slalom, perfect wakeboard, and perfect surf from one boat is within reach.
Speaking of surfing, there’d be no CO fumes. Teak surfing anyone? This would not only be more environmentally friendly, but more pleasant for everyone when idling. We’d also be able to forego starting/killing the engine every time a skier or rider is down.
Unlike a car on a roadtrip, an electrical boat system would in most cases be able to tow people for an entire day on a single charge. No more trips to the marina or hauling cans when out of petrol. Of course some of us would miss catching up on the latest lake gossip at the marina, but we can still stop in for other purposes. So, plug it in overnight and it’s ready for the next day.
Electric drive is also quiet and smooth. These are both kind of strange in a car, but would be heaven in a boat. Imagine no more vibration. For
Finally there’s cost. A very quick calculation gives us $90 for a day of petrol or $22 for a day of electricity. That’s nothing to sneeze at. Theoretically maintenance will be less as well, though I’m not sure I’d want to speculate until we’ve seen a ton more real data on battery/motor life.
So there you have it. I’m sure there are negatives that I haven’t thought of, but perhaps there are more positives as well.
