Anyone ever heard of a California GoPed? Back in the day they made some cool little scooters that were motorized, snappy, and expensive. These days they have advanced alot and they became quiet, faster, more cumfy, and really expensive. The snazzy units can go for as much as 4 grand Still, other units are more economical and they would even fit in a 20 foot Barth if one were so inclined and had the budget for such a thing.
