Abstract: A method for making a composite panel includes the step (26) of providing a panel having elongated channels (14) that are positioned along areas of anticipated point compression loading. The panel (10) has a reinforcing fabric layer (41) attached to a non-woven fabric layer (43) forming an outside layer (12). The composite panel has foam core (8,9) within the outside layer. The method further comprises the step (27) of providing structural foam channel inserts (16) having an outer fabric layer (18), wherein the channel inserts have a cross section which matches the cross-sectional profile of each of the elongated channels of the panel. Resin is then applied to the outside layer of the panel and outer fabric layer of the channel inserts such the channel inserts are positioned within the channels of the panel (29 and 31). The resin is then allowed to cure (33) forming a composite structure.

Abstract: Boat hull or attachment with a plurality of longitudinally movable elements. Presently preferred embodiments utilize wings or ski members which are movable and maintainable between multiple positions to adjust the operational characteristics of the boat. The wings extend from the transom longitudinally along the aft half of the boat and include upwardly curved foil shaped front edges to provide lift. The ski members will generally extend along a substantial extent of the length of the boat. Bottom running surfaces of the respective ski members may be varied in angular disposition to operatively simulate a plurality of hull configurations.
