An inner frame is telescopically positioned within an outer frame to be mounted horizontally on top of a vehicle. Folding rails for a ramp are pivotally joined to the rear end of the inner frame, and when the inner frame is extended, the ramp is positioned far enough back of a vehicle to permit a boat to be inverted while it is being supported on the top portion of the ramp. A carrier bar follows the rails and has, for connection to oarlocks, fastening means that permit a boat to be inverted easily by being rotated about the bar. The movements of the carrier bar and telescopic frame are controlled by winches.
