The boat trailer includes segmented bunk board covers, with the segments being of different lengths so that they can be combined to cover different lengths of bunk boards. The bearing surfaces of the bunk board covers include a series of oppositely sloped lifting edges that tend to lift the facing surface of the boat hull so that when the boat is tilted on the trailer, the lowermost surface of the boat hull tends to apply more weight to one of the bunk boards, so that the lower surface tends to be lifted by its bunk board.
