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.

[ We claim:] [1.]1. An electric powered watercraft capable of exceeding its calculated hull speed comprising:(a) at least one elongated submerged support member having an upper surface and at least one strut attached to the upper surface;(b) a propulsion unit and a low energy density power source within the at least one support member, wherein the low energy density power source comprises at least 25% of the total watercraft weight;(c) at least one float having an upper surface and at least one strut attached to the upper surface; and(d) a platform attached to the upper ends of the struts and held above the support member(s) and float(s).
