Electric boats are much more prevalent in Europe than they are in North America. And I don’t just mean slow speed harbor launches and auxiliary sailboats either. I boarded any number of boats with center console or small cabin layouts in the 20 to 30 foot long range that could deliver planing performance for maybe an hour, and still allow you to enjoy a few more hours under power (at slow speed) before needing to be recharged. In other words, these boas could deliver an, “average afternoon on the water. “ Consider this notional trip: You run at 25 knots to a beach, anchor and swim for a while; then, you slowly troll for fish for an hour; next , lines up and you zoom at 25 knots for 15 minutes to a lunch spot; next, you cruise slowly towards home for an hour, enjoying each other’s company and the view; the final mile is a burst of speed to the dock and you still have an hour’s worth of trolling speed ability in reserve. The batteries charge overnight on a 15-amp circuit. Such boats are real. Check out for example.
