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.

[ We claim:] [1.] A watercraft, comprising:(a) at least one elongated, submerged support member having a convex upper surface;(b) a propulsion unit and a low energy density power source within the support member;(c) at least one floating ski positioned parallel to the support member; and(d) a platformwherein the support member and the at least one floating ski are positioned parallel to each other with the support member positioned lower than the ski and both hold the platform above the water surface via struts to allow at least some wave motion to pass unimpeded between the water surface and the platform, and wherein the low energy density power source comprises at least 10% of the watercraft weight.
