The invention relates to an inflatable surfboard with an inflatable hull component with two lateral arms (7a, 7b) which form a receptacle, and drive unit (6) which forms an outer contour which fits into the receptacle in a positively locking manner, and at least one fastening means (23, 23a, 23b, 24a, 24b, 26a, 26b, 27, 27a, 27b, 28, 61a, 61b) at the stern end of the surfboard (1), wherein the at least one fastening means (23, 23a, 23b, 24a, 24b, 26a, 26b, 27, 27a, 27b, 28, 61a, 61b) is inelastic.

An improved method for building a lapstrake boat 240 includes an improved strake structure 152 having a wide rabbet 182 running the length of said strake's lower edge 164 and inside face and having a selected rabbet width which defines a joint overlap region with a bond receiving gap 210. The strake's rabbet width is preferably three times the plank's thickness 180 along most of its length but may taper. A plurality of temporary tie receiving holes 220 are bored through the thickness of the strake, and entirely within the rabbet segment of the strake for coaxial alignment with adjacent holes 224 in the adjacent strake. Adjacent strakes 150, 152 are aligned and tied together so that the wide rabbet segment 182 in the bottom edge of one adjoining strake 152 overlaps and is tied to a selected surface area on the outside face of the adjoining strake 150.

A flexible inflatable container that includes a flexible inflatable core having opposing first and second panel members, each with an interior side. A plurality of longitudinally oriented stringers is disposed on at least one interior side of one of the opposing first and second panel members. Each stringer has at least one edge. Zippers join stringers portions to one another or to the panel members or both. An inflation valve on one of the panel members is provided for introducing fluid into the flexible inflatable core. The core is covered by a flexible outer skin.

A cockpit covering system for a small boat comprises a tent or cover comprising a plurality of walls portions, each of the plurality of wall portions having a lower portion and wherein the tent is sized to extend over a recessed area of a cockpit and enclose an interior that extends from above deck height to below the height of a base layer. The base layer is attachable to the lower portion of each of the plurality of walls and positionable around the cockpit outer perimeter. A compressible gasket below the base layer rests on a deck of the small boat around the cockpit outer perimeter. A plurality of webbing straps extend from the outer perimeter of the boat to the cockpit outer perimeter and are attached to the tent covering system. Tension applied to the plurality of straps extending from the small boat outer perimeter to the cockpit outer perimeter compresses the compressible water and/or bug proofing layer to form a seal around the cockpit recessed area. Pole bracket housings may be provided on webbing straps to secure tent poles at deck level at various locations on the deck.
