  • Inflatable boat and deck therefor
    Patent number: 5088434
    Abstract: A deck apparatus is disclosed containing interengagement means between an inflatable boat and a plurality of adjacent deck elements which are joined by a resilient link. The interengagement means prevent relative vertical movements of the adjacent deck elements and substantially all angular movement in one direction, but freely permit relative angular movement in the other direction whereby the adjacent deck elements may be folded on top of one another with the link allowing in principle, 180 degrees of relative rotation.

  • Attachment of tubes in inflatable boats
    Patent number: 4934301
    Abstract: To secure a tube (6) to the hull (4) of a rigid inflatable boat (2) a rigid plate (10) is retained at the outside of the tube by means of a pocket (14) and there offers an anchorage for securing means (e.g. nut and bolt 22,24) penetrating a flange (12) of the hull.

  • Self-bailing inflatable boat
    Patent number: 4744326
    Abstract: Apertures in the floor of an inflatable boat are provided to render it self-bailing. They are formed by grommets penetrating the permanently-attached, continuous and integral floor which extends from one lateral buoyancy tube to the other, preferably in a thickened region thereof comprising a flange attachment to the tubes. They are overhung by the buoyancy tubes, when the floor is generally horizontal. An area in the central region of the floor is raised above the waterline of the boat.

  • Securing inflatable tubes to rigid hulls
    Patent number: 4628854
    Abstract: A boat has an inflatable buoyancy tube attached to a rigid hull by clamping an edge portion of the hull between flexible flanges secured to the tube, using comparatively rigid clamping strips. The clamping strips are pressed together by a releasable securing arrangement passing through the gunwale of the hull, for example nuts and bolts spaced along the strips. Tightenable straps anchored by the bolts may be added for extra security.

  • Inflatable boat
    Patent number: 4603651
    Abstract: An inflatable boat is provided with a multi-keel by having an inflatable member or members constrained to lie between the flexible skin of the boat and a reaction surface. Preferably there is a rigid deck as a reaction surface overlying the flexible skin with two parallel inflatable tubes under the deck spaced apart by a distance equal to half the width of the deck.
