Abstract

Abstract This invention consists primarily of a catamaran type of boat, which includes a main frame upon which is a deck and two standard canoes for use as pontoons. The canoes are converted into pontoons by the addition of light weight cellular floatation material, which makes them virtually unsinkable. The canoes are pivotable between a position along each outer side of the main frame for wide spaced apart support upon the water. The arrangement includes a means whereby the canoe-pontoons are pivoted upward on top of the deck, so as to be out of the way and contracting the pontoon boat width, when being towed as a trailer upon the highway, the underside of the main frame supporting downwardly pivotable wheel assemblies, for travel on the highway surface.

Claim 1
Independent Claim 311 words
A pontoon boat, comprising in combination, a rectangular main frame having a deck thereupon, said main frame including a pair of longitudinally telescopic tubes and a plurality of four transverse telescoping tubes, said transverse telescoping tubes being sidewardly extendible beyond a side edge of said main frame, outward extended sections of said transverse telescoping tubes each being secured to a mounting frame, said mounting frame being secured to two pontoons, each of which is made of a standard canoe, and said pontoons consisting of said canoes being filled with a suitable light weight and cellular flotation material, said canoes being covered so as to be watertight and serving as a strong decking, each said outward section of said transverse telescoping tubes being hingedly pivotable, so that said pontoons are pivotable between a position along each side of said main frame and a position upon said deck; a strengthener being insertable into each of said transverse telescoping tubes for bridging said hinge, in order to rigidly lock said outward section thereof to a remainder of said transverse telescoping tube; a pair of wheel assemblies being pivotally attached to an underside of said main frame for being upwardly retracted out of the way, or in a downwardly extended position for travel upon a highway, said wheel assemblies in downward extended position being secured by braces; said pontoon boat including a forwardly telescoping tongue for attachment to a towing vehicle, said pontoon boat including a forwardly pivotable ladder secured by a hinge to a forward edge of said deck; and a removeable rail around a periphery of said deck being comprised of a plurality of railing sections spaced apart end to end, each one of said railing sections being comprised of three vertical posts and a pair of panels, both of which are supported pivotally by hinge means from a center of said posts.
