ABSTRACT:
A sliding boat trailer roller mount is used when loading or unloading a boat from a boat trailer. The roller mount includes a mounting arm with an arch, a saddle with a curved groove in which the mounting arm rocks and slides, and a roller at each end of the mounting arm. A pair of saddles are attached to the ends of a pivot arm. A plurality of pairs of pivot arms are pivotally mounted on a boat trailer. The curvature of the mounting arm is such that it slides and pivots within the curved groove of the saddle, allowing the rollers to follow the compound curvature of a boat hull during loading or unloading.
