ABSTRACT:
The object of this invention is to provide a prefabricated boat consisting of a reinforced plastic boat body (1), and a rubber tube (2) detachably attached along each side of the body (1) to give buoyancy to the body (1). The sides of the boat body (1) each have a longitudinal guide groove (4) designed such that the tubes (2) are closely attached to the body (1) with enlarged contact surfaces between the tubes (2) and the body (1). Upper and lower brackets (6), each having a fitting groove (5), are formed along the upper and lower edges of each guide groove (4). Each tube (2) has two slidable fittings (7) engaging with the fitting grooves (5) of the two brackets (6). This boat thus minimizes hydraulic impact energy applied to the tubes (2) during a voyage, thus improving its sailing stability and cruising power as well as increasing its mileage.
