  • Patent number: 4295236
    Abstract: A relatively small watercraft typically used by one or two persons includes a pair of spaced and usually parallel pontoons, each of which consists of an elongated body of closed-cell foamed plastic such as polystyrene. A load-distribution truss is provided on top of each of the foamed cell bodies, for transferring vertical loads to said bodies. A personnel station extends generally between the two spaced pontoons and above said pontoons. The personnel station includes a chair and a floorboard, and is sufficiently narrow so as to restrict personnel on the station to a central portion of the watercraft. A structural frame of tubular members or the like may be selectively connected to the pontoons, or the frame may be permanently connected to them. In one embodiment wherein the structure frame and the pontoons are only temporarily connected, a plurality of eye bolts and specially positioned slots are utilized so that the eye bolts need never be removed from the watercraft.

  • Patent number: 4271549
    Abstract: A relatively small watercraft includes a pair of spaced and usually parallel pontoons. A personnel station extends generally between and above the two spaced pontoons. A structural frame of tubular members or bars supports the personnel station; the tubular members may be selectively connected to the pontoons, or the frame may be permanently connected to them. In one embodiment wherein the structural frame and the pontoons are only temporarily connected, a plurality of eye bolts and specially positioned slots are utilized so that the eye bolts need never be removed from the watercraft. (In this embodiment, there are no connecting pieces to ever get lost, even when the three main sub-assemblies of the watercraft are disassembled.) The eye bolts are aligned longitudinally with the slots for disassembly, and turned transversely to the slots to hold the tubular members to the pontoons. Dimples or recesses in the tubular members can be provided to inhibit unwanted rotation of an eye bolt.
