A self-loading and unloading trailer which can be operated by a single person to load a boat from difficult boat ramps or even directly from the ground provides rollers for engaging a boat. A first set of rollers engages the boat at ground level, enabling the boat to be winched directly from the ground or from a shallow landing. As the boat is loaded, the rollers shift and transfer the load directly to a second set of rollers. Finally, the boat weight shifts the trailer again, causing the rollers to retract, thereby bringing the boat to safely rest on bunks for storage or during transit. In the preferred embodiment, the boat is a pontoon boat, though other appropriate boat hulls are contemplated for use with the present invention.
