发明名称 Amphibious multihull boat
摘要 A boat including a main hull, a first pontoon hingedly connected to the main hull, and a second pontoon hingedly connected to the main hull on an opposite side of the main hull from the first pontoon. The first and second pontoons have wheels extending outwardly beyond a surface of the first and second pontoons. The first pontoon is selectively movable between a first position extending outwardly of the main hull and a second position extending below the main hull. The first wheel extends below the first pontoon when in the second position. The second pontoon is also selectively movable between a first position extending outwardly from the main hull and a second position extending below the main hull. The second wheel extends below the second pontoon when in the second position. A first strut section extends between the main hull and the first pontoon. A second strut section extends between the main hull and the second pontoon. The strut sections include deck surfaces extending across the boat. A bowsprit is hingedly connected to a forward area of the main hull and is movable between a position above the main hull to a towing position below the main hull.
