ABSTRACT:
An insert for a roller for supporting a boat on a boat trailer includes a plastic sleeve surrounding a stationary shaft for the roller. The sleeve includes a plurality of spaced-apart longitudinal ridges extending radially outward along its length. A hollow rubber roller is fitted over the sleeve and the ridges are embedded into an interior diameter of the rubber roller, so that air circulates freely between the sleeve, the ridges and the roller. The roller may include load bearing sleeve supports, between the shaft and the sleeve, at each end of the insert.
