Abstract: A system for detachably connecting a wing to a pair of spaced hollow hulls to complete a deck assembly for a boat, such as a catamaran. Each hull has an upwardly extending, open ended hatch cone which communicates with the hull interior. The hatch cones are received through respective hatch openings formed at opposite sides of the wing for aligning the wing with the hulls. Each hull has a plurality of holes formed therethrough which are aligned with a corresponding plurality of receptacles located in the bottom of the wing. Fasteners are removably inserted through respective holes in the hull for receipt by the receptacles of the wing, whereby the wing is detachably connected to the hulls. The fasteners are located through the holes and into the receptacles from the interior of the hollow hulls and by way of the open ended hatch cones which communicate therewith.

Abstract: A method and apparatus for making a boat, or similar vessel, having a hull section to be bonded to a deck section. Pairs of pivotal arms are located adjacent the hull and adapted to be rotated in a first direction towards each of the sides thereof. A plurality of vacuum assemblies, each assembly including a vacuum cup, are attached to the pivotal arms and movable therewith toward the sides of the hull. A vacuum line is connected in common with each of the vacuum cups by which to establish a vacuum for causing the cups to become firmly attached to opposite sides of the hull. When the pivotal arms are rotated in a second, opposite direction, the hull is correspondingly pulled into contact with a peripheral lip of the deck. A layer of glue is deposited around the peripheral lip of the deck, so that the deck and hull sections will be bonded together to form a complete hull.
