PCT No. PCT/CA92/00174 Sec. 371 Date Dec. 7, 1992 Sec. 102(e) Date Dec. 7, 1992 PCT Filed Apr. 24, 1992 PCT Pub. No. WO92/19491 PCT Pub. Date Nov. 12, 1992.A novel stable inflatable or inflated sail board is provided. The sailboard includes a plurality of discrete, gas-fillable or gas-filled, elongated chambers, each chamber having a top skin and a bottom skin, each chamber, when inflated being sufficiently rigid to maintain its shape without any additional support, and to provide a flat bottom surface for contact with water, the chambers being integrally united to provide an elongated float which is of greater length than width. The sailboard also includes a supporting and stiffening rigid frame comprising a plurality of frame sections which are interconnectable with each other in a longitudinal direction, the frame supporting the floatation member and providing additional stiffness and resistance to fore-and-aft bending and torsion. Finally, the board includes a rigid platform, which is of the same width as the floatation member but which is of less length, the rigid platform being firmly held to the top skin and being directly and rigidly connected to the rigid frame. The gas-filled chambers, the rigid frame and the rigid platform together provide an integral unitary assembly which imparts additional rigidity to the flat bottom surface of the floatation member and also imparts stiffness in a transverse direction to the floatation members.
