ABSTRACT:
A watercraft mounted on submarine hulls is taught which is capable of moving faster than a displacement vessel of the same length, while consuming equal or less fuel than would such a displacement vessel. The watercraft also has improved safety and stability characteristics, including the capability of operation in a raft configuration as well as the capability of beaching or parking in shallow water such that wave action does not affect the cabin occupants.
