Abstract: A method of constructing a marine vessel. The method includes structurally interlaminating a first plurality of components to form a first element of a marine vessel, structurally interlaminating a second plurality of components to form a second element of the marine vessel, and structurally interlaminating at least a first portion of the first element with at least a first portion of the second element to form a first combined element of the marine vessel. Also, a marine vessel. The marine vessel includes a first element including a first plurality of structurally interlaminated components, and a second element including a second plurality of structurally interlaminated components, wherein at least a first portion of the second element is structurally interlaminated with at least a first portion of the first element.

Abstract: A wooden hull construction for a watercraft, particularly a canoe, includes a multiplicity of boards, each board individually secured to adjacent boards while maintaining parallel alignment. In an aspect of the hull construction wherein there is a single layer of boards, the boards are secured together in parallel alignment along their lateral edges with adhesive. In multiple-layer hull construction aspects, each layer of parallel hull boards is secured to an adjacent layer with board edge seams substantially offset from the board edge seams of the adjacent layer. Individual boards are secured directly to adjacent boards in the same layer or to boards in the adjacent layer, or both. The hull boards are aligned substantially transversely, i.e., gunwale to gunwale, of the watercraft.

Abstract: A method of manufacturing a watercraft which comprises a foam inner core (2) and an outer layer of natural bamboo veneer (3), the method comprising the steps of: (a) applying an adhesive to a plurality of sheets of bamboo veneer; (b) placing the sheet on the inner core (2); (c) drawing the sheets onto the core (2) under a partial on the inner core (2); (c) drawing the sheets onto the core (2) under a partial pressure environment; and (d) allowing the adhesive to cure.

Abstract: A method for building lapstrake boats without use of a strongback and molds, and without the need to cut bevels on the strakes. The two-dimensional shape of each strake is determined and the strakes are cut to these shapes. A groove, or rabbet, is cut in the bottom inside edge of each, but the bottom, strake. The strakes are fastened or clamped so the top edge of each plank fits into the rabbet in the bottom of the adjacent strake. This has the effect of holding the strakes in alignment. The joints are filled with epoxy or other cementitious material making a strong stiff bond. One or more frames, bulkheads, or other interior components may be inserted as needed to maintain the strakes in the desired shape.

Abstract: Disclosed herein is a boat hull including a stringer member having an end surface including therein a cut-out, and a projection extending beyond the end surface, a bulkhead member extending transversely to the stringer member, fixed thereto, and including an end surface extending in coplanar relation to the end surface of the stringer member and including therein a cut-out, and a projection extending beyond the end surface of the bulkhead member, a deck member engaging the end surfaces of the stringer member and the bulkhead member and including cut-outs respectively receiving the projections on the stringer and bulkhead members, and a gusset member extending substantially at a right angle to the stringer and bulkhead members and including a first projection received in the cut-out in the stringer member and a second projection received in the cut-out in the bulkhead member.

Abstract: This application relates to composite structures and, more particularly, to a composite or sandwich structure employing sheets of wood veneer.

Abstract: A new method of hull construction using double, longitudinal, sealed, alternate and prestressed wooden planking. The hull is formed of an inner layer of longitudinally extending planks and an outer layer of longitudinally extending planks alternately positioned over and glued to the inner layer. Both layers are attached to the ribs defining the hull framework. The inner layer planks are abutted and glued along their longitudinal edges. The outer layer planks are beveled along their longitudinal edges forming longitudinal grooves between each plank. Hardwood splines, running the length of the longitudinal grooves are glued and forced into the grooves.

Abstract: To join together at least two light dividing walls, resisting tensile forces and possibly curved, recourse is had to a plurality of fastenings (4,5) each extending radially in at least one direction from a pivot (6), the pivots of these fastenings being stacked axially along the axis L corresponding to the line of intersection of the mean surfaces of the dividing walls and the contiguous fastenings of the stack being oriented so that they extend alternately along said mean surfaces. The fastenings thus joined together at the level of the pivots form discontinuous wall portions whose roots are mutually imbricated, to which wall portions the dividing walls are then butt-jointed, themselves formed by parallel skins bonded to these wall portions and in which the intermediate space is filled in with foam.

Abstract: The hull of a wooden vessel is laminated and provided with an outer plastic skin which provides a hull of high structural strength, and protects the wood interior against rot and attack by marine organisms. In its preferred aspects, a skin of fabric-like fiberglass is chemically bonded (and preferably chemically and mechanically bonded) to a wooden hull constituted of wooden planking at least three-fourths inch in thickness by use of an elastomeric adhesive which, after curing, is capable of stretching at least twice, and preferably from about 3 to about 5 times its length, and the outer surface of the fabric-like fiberglass is saturated with resin, covered with a chopped fiberglass mat, cured, a fairing compound is applied to the exterior of the skin, and the surface is sanded and painted.
