New electric boat designs are provided that exploit the weight of a battery to stabilize the boat and in some cases to overcome the hull speed limitation problem. The battery mass is enclosed in one or two torpedo-like structures that are mostly or completely submerged. A platform is spaced above the torpedo(s) via one or more struts that may allow wave energy to pass through the watercraft rather than collide with large vertical surfaces. The design minimizes wake formation, wave sensitivity and is useful for new kinds of electric boats that can dive with an air bubble to allow submarine use, higher speed pleasure craft, and sailing craft that can remain stable in shallow draft waters. The stabilized watercraft optionally have computer monitoring of wave activity and control for greater resistance to adverse weather conditions.

Computer controlled watercraft

High speed electric watercraft of various configurations are provided that utilize at least one submerged enclosed hull containing an electric motor and at least one other parallel float positioned higher that the enclosed hull to provide buoyancy for a platform that can carry one or more individuals above a water surface. The watercraft optionally include features of (1) a rounded front end on the platform, (2) a platform length that is shorter than the float for stability against tipping, (3) entryways that do not require stepping over a vessel hull, (4) dimensions fore and aft that minimize spray onto the rear of the platform, (5) shock absorbers to provide a smoother ride, and (6) adjustable struts that connect floats with the platform to allow control of the platform height above the water surface. These and other features are made possible by a fast electric design that avoids certain problems of vessel type watercraft.

High speed electric watercraft

Stabilized electric watercraft for high speed cruising, diving and sailing

Electric powered watercraft that lack an open-hull capsizable design utilize a low energy density heavy power supply for stabilization. The power mass is enclosed in one or two torpedo-like structures that are mostly or completely submerged. The structure(s) are combined with at least one enclosed float, preferably of convex shape. A platform is spaced above the float(s) via struts that allow wave energy to pass through the watercraft rather than collide with large vertical surfaces. The design also minimizes wake formation. This configuration of a low-energy density power supply, particularly within tapered hull(s) is useful for electric powered houseboats and personal pleasure craft that can withstand stormy conditions more easily than equivalent sized open vessel designs.
