Super high speed multi-hull watercraft

A watercraft with at least one onboard propulsion engine, comprising:

• at least two hulls in spaced-apart parallel relationship to each other, including a port hull and a starboard hull;
• a deck structure spanning the port and starboard hulls, said deck structure extending laterally beyond the port hull to a port side of the deck structure and laterally beyond the starboard hull to a starboard side of the deck structure;
• a port skirt extending vertically downward from the port side of the deck structure that combines with the port hull and the deck structure to form a forwardly opening and rearwardly extending port planing channel;
• a starboard skirt extending vertically downward from the starboard side of the deck structure that combines with the starboard hull and the deck structure to form a forwardly opening and rearwardly extending starboard planing channel;
• and
• means for providing aerodynamic lift from air passing over the deck structure, including an upwardly facing surface of the deck structure that slopes downwardly toward an aft end of the deck structure in order to produce aerodynamic lift;
• wherein the deck structure includes means for reducing vessel breadth during docking, including hinged port and starboard deck extensions that an operator can selectively raise and lower.

• wherein the deck structure includes means for enabling an operator to adjust vessel trim, including hinged flap structures disposed rearwardly on the deck structure.

A watercraft with at least one onboard propulsion engine, comprising:

• three hulls in spaced-apart, parallel relationship to each other, including a port hull, a starboard hull, and a central hull intermediate the port and starboard hulls;
• a deck structure spanning the three hulls, said deck structure extending laterally beyond the port hull to a port side of the deck structure and laterally beyond the starboard hull to a starboard side of the deck structure;
• a port skirt extending vertically downward from the port side of the deck structure;
• and
• a starboard skirt extending vertically downward from the starboard side of the deck structure;
• wherein the three hulls, the port skirt, the starboard skirt, and the deck structure form four forwardly opening and rearwardly extending planing channels;
• and
• wherein the deck structure includes an upwardly facing surface that slopes downwardly toward an aft end of the deck structure in order to produce aerodynamic lift;
• said watercraft further comprising at least one planing surface on each of the three hulls and at least one vertical step in each of the planing surfaces;
• and
• said watercraft further comprising means for venting exhaust from the onboard propulsion engine at the vertical steps, including a speed-responsive exhaust proportioning system that allows vacuum generated at the vertical step in the planing surface to draw in exhaust increasingly with increasing vessel speed.
