A boat trailer specifically designed to permit retrieval thereof when the wheels rotatably mounted thereon have fallen off an underwater precipice of the type often encountered when launching a boat at a boat ramp. A pair of wedge or ramp shaped members are integrally formed with or fixedly secured to the underside of a conventional boat trailer frame, just forwardly of the trailer wheels. The respective base portions of the ramp members abut the underside of the side rails of such trailer frame, and the respective trailing edges of the ramp members depend to such base portions, just forwardly of the respective wheel members, extending to a point just below the axis of rotation of such wheel members. The respective operative surfaces of the ramp members correspond to the hypotenuse of a triangle and slidingly engage the transverse edge of the precipice when the trailer is retrieved from the water.
