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.
