ABSTRACT:
A water jet propelled boat that includes a source of pressurized air that by a single action control may be delivered to bow and stern portion positioned resilient bags to inflate the same to vary the contour of the wetted portion of the boat to a desired configuration. The boat includes a number of laterally spaced sponsons that have forward bottom surfaces that taper downwardly to merge into substantially straight rearward bottom surfaces on which the boat rides when traveling at high speed. Pressurized air is discharged from the source to flow rearwardly under the boat and impart a lift to the latter. The desired configuration of the bags is one which in combination with the action of the sponsons and the rearwardly flowing bubbles results in the boat moving through the water in a fuel efficient manner.
