2 transom lines suspend the boat at the bumper. 2 winch lines connected to the power roller reach out to the forward part of the boat.
The front roller acts as a pulley when the winch lines wind around the power roller, lifting the bow while pulling the boat against the rear bumper.
The boat rotates around the rear pivot roller while suspended by the rear transom lines.
The two winch lines pull the boat forward and down toward the front roller.
The bow lands on the front roller and the boat is pulled forward to the tie down location of the winch line connection in the forward part of the boat.
The boat becomes fully loaded and automatically tied down front and rear with four 1900 lb test lines. Unloading occurs by reversing the direction of the power roller, which drives the boat off and through the opposite sequence of loading.
