The improved watercraft comprises an underwater pod or pods, that support a pecentage of the displacement of the watercraft at rest. The percentage of displacement produced by the pods could vary widely based upon the purposes of the watercraft and its intended range of uses, i.e., speed, water conditions, cargo, length, etc. The improved watercraft is also comprised of one or more hulls at the surface, which when at rest, displace most of the remainder of the watercraft\s total weight. The rest of the watercraft\s displacement, normally a small percentage, is comprised of hydrofoils, or wings, and these provide lift for the watercraft when under way. These hydrofoils or wings would normally be designed to be sufficient in area and dynamic lift to raise the surface hull clear of the water\s effects, if that was desirable for the intended purpose.

An improved watercraft comprising: an elongated hull which has a predetermined displacement as a free standing component floating on the water, said hull having a top surface, a bottom surface and laterally spaced side surfaces; at least one elongated underwater pod located at a position in the water below the bottom surface of said hull, said pod having a water displacement volume sufficient to displace between 25% to 85% of the total displacement of said hull; strut support means rigidly connecting said hull to said underwater pod to produce a predetermined vertical spaced relationship between them; and at least two foil shaped struts each having a first end and a second end, the first ends of said foil shaped struts being connected to said underwater pod, the respective second ends of said foil shaped struts being connected to a different lateral side surface of said elongated hull.
