An inflatable structure that includes continuous longitudinal and axial curves, constructed to form a hydrodynamically designed performance platform for use as a performance water sports board, rescue board, or rescue sled, such as a stand-up paddle board, paddleboard, surfboard, PWC rescue sled, bodyboard, or other floating or dynamic platform. Alternatively, it may be adapted for use with additional structure to provide an inflatable hull and floor for a watercraft, such as a boat, raft, life-raft, rescue craft, or other floating or dynamic platform. Longitudinal stringers welded to opposing panels defining the interior volume of the inflatable structure are joined by welding, gluing, or lashing, and the shape of the stringers and the welding/gluing/lashing schedule can be employed to give the inflatable structure a highly customized curved shape.

1. An inflatable watercraft, comprising: a first flexible panel having an interior side and an exterior side;a second flexible panel having an interior side and an exterior side, said second flexible panel joined to said first flexible panel to form a sealed interior volume;an air valve;a first plurality of stringer panels each having a top portion and a bottom portion, said top portion attached to said interior side of said first flexible so as to impart deck contour to said first flexible panel and the bottom portion spaced away from the interior side of the second flexible panel; anda second plurality of stringer panels having a bottom portion attached to said interior side of said second flexible material panel and positioned in relation to said first plurality of stringer panels so as to form pairs of opposing stringers panels and so as to impart bottom rocker to said second flexible panel, wherein each stringer panel of said second plurality of stringer panels in an overlapped manner to the to a bottom portion of an opposing stringer panel in said first plurality of stringer panels said top portion of the second plurality of stringer panels spaced away from the interior side of said first flexible panel, wherein said stringers are oriented substantially parallel to the longitudinal axes of the first and second flexible panels, and, wherein the shape of said stringers and the connection between opposing stringers imparts contour to each of said first flexible panel and said second flexible panel when said inflatable watercraft is inflated. 2. The inflatable watercraft of claim 1 configured as a sports board. 3. The inflatable watercraft of claim 2, further including fins. 4. The inflatable watercraft of claim 3, wherein said fins are installed in fin base holes in said second flexible material panel. 5. The inflatable watercraft of claim 3, further including fin base anchors disposed on said interior side of said first flexible material panel. 6. The inflatable watercraft of claim 1, wherein said air valve is positioned in a rear portion of said first flexible material panel. 7. The inflatable watercraft of claim 1, wherein said stringers have a profile that defines a shape of both of said first flexible material panel and said second flexible material panel when the inflatable structure is assembled. 8. The inflatable watercraft of claim 7, wherein said first and second flexible material panels are joined at their edges. 9. The inflatable watercraft of claim 8, wherein said opposing stringer panels are overlapped and bonded to one another. 10. The inflatable watercraft of claim 8, wherein said opposing stringer panels are joined to one another using cordage lashings. 11. The inflatable watercraft of claim 10, wherein said air valve is configured to provide access to said interior volume so as to permit adjustment of lashing tension. 12. A method of manufacturing and assembling an inflatable watercraft, comprising: laying out first and second flexible material panels;cutting the first and second flexible material panels to a shape suitable for the particular kind of inflatable structure under construction;marking the first and second flexible material panels for bonding;installing a valve reinforcement patch in an interior side of one of the first and second flexible material panels;cutting a valve hole in the flexible material panel at the valve reinforcement patch;installing a first set of stringer panels on the first flexible material panel;installing an opposing second set of stringer panels on the second flexible material panel such that when the first and second material panels are approximated in assembly, the first set of stinger panels overlap and engage stringer panels in the opposing second set of stringer panels;connecting the first set of stringers to their respective opposing stringers in the second set of stringer;wherein the first set of stringers have an upper portion affixed to the interior side of the first flexible material panel and a lower portion spaced away from the interior side of the second flexible material panel, and wherein the second set of stringers have, a lower portion affixed to the interior side of the second flexible material panel, and a top portion connected to the lower portion of the first set of stringers in an overlapped manner, said top portion spaced away from the interior side of the first flexible material panel, wherein said stringers have a medial portion defining a plane generally normal to the interior sides of the first and second flexible material panels, the internal stringers oriented generally parallel to the longitudinal axes of the first and second flexible material panels, and further wherein the stringers have a profile as seen in side view in elevation that defines the shape of the first flexible material panel and the second flexible material panel when the inflatable watercraft is assembled;folding over a portion of the perimeter of the first flexible material panel and welding the folded portion to a perimeter of the second flexible material panel, leaving an end of the inflatable watercraft open;closing the open end by hand gluing or welding;installing an air fill valve in the valve hole; andinflating the inflatable watercraft by introducing air into the watercraft through the air valve. 13. The method of claim 12, wherein the inflatable watercraft is a sports board, and further including the step of cutting fin base holes in the second flexible material panel. 14. The method of claim 13, further including bonding fin base anchors to the interior side of the first flexible material panel. 15. The method of claim 14, further including bonding fin bases in the fin base holes. 16. The method of claim 12, wherein the opposing stringer panels are connecting using a lashing arrangement. 17. The method of claim 12, wherein the stringers in the first set of stringers are bonded to the interior side of the first flexible material panel and imparting deck contour to the first flexible material panel, and bonding lower portions of the second set of stringers to the interior side of the second flexible material panel to impart bottom rocker or bow/stern profile. 18. The method of claim 17, further including attaching lashing anchors to the interior side of the second flexible material panel adjacent the ends of the stringers at an end of the inflatable watercraft. 19. The method of claim 12, wherein the first and second sets of stringers are joined using welding or bonding. 20. The method of claim 19, further including coating the structure of the inflatable watercraft with a protective coating.
