A watercraft constructed according to the invention includes at least one hull according to the invention described in the grandparent and great-grandparent patent applications that issued as U.S. Pat. Nos. 6,314,903 and 6,250,245, which hull includes first and second channel defining structures connected to the hull that define a first channel on a port side of the hull with a forwardly facing first channel entrance and a second channel on a starboard side of the hull with a second forwardly facing channel entrance. According to one aspect of the invention, the hull has a bow that extends to a vertical knife edge, and the first and second wing channel entrances are arranged to form a near horizontal knife edge at the deck level in order to enhance high speed operations. According to another aspect of the invention, there is provided an onboard air system for injecting air into the first and second channels in order to enhance high speed operation of the watercraft. The air system may include a blower powered by an on-deck auxiliary power unit, a blower powered by a main drive diesel or gas turbine, components that divert excess air from a main drive gas turbine, or components that divert exhaust from a jet engine main drive.
