A catamaran design has a third hull positioned between the conventional hulls. The third hull has a length equal to about two-thirds of the length of the conventional hulls, and a recess is formed in the underside of the deck aft of the third hull. The recess has a depth sufficient to accommodate the rooster tail created by the third hull. The third hull enhances the buoyancy of the craft and prevents formation of waves under the leading end of the deck. The recess prevents the rooster tail from impinging against the underside of the deck. The third hull produces a concave wake and it is submerged to a similar extent as the twin hulls when the watercraft is at rest floating in a body of water. In combination, the third hull and recess provide a catamaran that can handle heavy seas, with control and safety, that is not subject to the pounding of waves on the underside of its deck, and which performs in all other respects like a conventional catamaran.

An anchor davit comprising an elongated U-shaped frame for receiving a main shank of an anchor; a roller at the outboard end of the frame for guiding the anchor line as it is lowered or raised; means at the outboard end of the U-shaped frame for providing chafe protection of an anchor line when the anchor is deployed and for providing captivity of the anchor when the anchor is being raised and secured; and means at a rear portion of the flat bottom portion juxtaposed the rear of the U-shaped frame for securing the U-shaped frame to a bow, a deck, a gunnel or another structural member of a boat. The means at the outboard end of the U-shaped frame for providing chafe protection of the anchor line and for providing captivity of the anchor comprises a smooth round rod. The round rod forms an arcuate shape above and between the sides of the U-shaped frame, extends downwardly along respective edges of the sides and further extends a predetermined distance below said sides and forms an arcuate shape in a direction toward the rear of the U-shaped frame, ending at a respective opposite edge of an extended vertical portion of the sides which extends below the flat bottom portion. The rod is welded to the edges of the sides with which the rod is in contact and the arcuate shape formed above and between the sides of the U-shaped frame serves as a bail for captivating the anchor line or the shank of the anchor.

A system for minimizing the effects of shock and vibration in a high speed vessel with an inner hull and an outer hull. It is a system of dampers, springs and stabilizer linkages in a high speed vessel that control the relative motion of an inner hull to an outer hull, thereby minimizing the effects of shock and vibration in the inner hull. Leaf spring assemblies may be used or as a substitute, torsion rod assemblies may be used, both in combination with dampers such as shock absorbers.
