Abstract
A bunk-style boat tailer is made with aluminum side rails and aluminum cross beams. A wheel and axle assembly is attached to the side rails near the rear of the trailer. The bunk beams are positioned so that approximately 3/4 of the length of the bunks is rearward of the axle mounting position. A front support of the bunk beams is attached to the side rails just forward of the axle mounting position. A rear support of the bunk beams is attached to the side rails at their rearward end. This cantilevers approximately 1/3 of the length of the bunks beyond the rear of the end of the side rails. A truss assembly structure transfers the load from the bunk supports to the wheel and axle assembly thereby reducing further the bending forces on the trailer side rails. This truss assembly also boxes the bunk support region of the trailer frame to reduce torsion forces. A wiring harness channel extends the length of at least one side rail.
