发明名称 Frameless pontoon boat
摘要 A frameless inflatable pontoon boat in which the pontoons and connecting section have a generally flat top and a generally flat bottom. Sufficient rigidity is achieved in the connecting section and the pontoon by the use of internal thread connections between the top surface and the bottom surface. The internal thread connections confine the inflated shape of the pontoons and connecting section to a flat shape.
