ABSTRACT:
A watercraft has at least two narrow hulls with a shallow draft and has one or more passive flotation devices that are entirely submerged. The hulls enclose the power trains for the watercraft and are accessible from the compartments of the watercraft. The passive flotation devices do not include a power train or any other equipment requiring access from the compartments of the watercraft. The narrow, shallow draft hulls have low friction drag and produce a small bow wave. Thus, the watercraft is able to be propelled rapidly, to be propelled for a greater distance, and to be propelled efficiently by the power provided by smaller motors and lighter energy sources.
