Abstract
The chassis connects adjacent flotation members each having supports projecting therefrom for attaching to the chassis. The chassis includes a pair of beams having opposite ends and sides with an end flange affixed to the ends of the beams. A plate is affixed to one of the opposite sides of the beams and has a length greater than the beams to form extension surfaces at each end. The extension surfaces are connected to the supports on a first plane and the end flanges are connected to the supports on another plane, preferably perpendicular to the first plane and vertical to the ground. The beams are preferably I-beams having a web and opposing extending sides perpendicular to the web. The top side is longer than the web and other side so as to form a tine which is received in a recess in the end flanges. Further, preferably the end flanges project beyond the end flanges and the opposing sides of the I-beam to form a border area having a plurality of apertures adapted to receive fasteners, such as nuts and bolts. The extension surfaces also include a plurality of apertures adapted to receive fasteners.
