"How many miles per gallon does it get?" You ask. That's kind of hard to answer; the Vectrix is electric. From fully discharged it takes about two hours to bring it up to 80 percent charged using the built-in charger. A function of the throttle regen engine braking charges the battery and can extend its life by up to 12 percent, the company says. It's powered by a 125-volt nickel-metal hydride battery that has a life of 10 years. At 462 pounds, it's going to take a little effort to get it aboard the boat, but when it's time to explore it'll be worth it. A five-foot wheelbase gives a nice smooth ride and of course, there's virtually no noise from the electric motor.
