Upwardly extending pivoting booms are supported on a rectangular base which is submerged in water. Watercraft supports on mounting arms are connected to the pivoting booms. A double-acting hydraulic cylinder attached between the rectangular base and pivoting booms swings the pivoting booms upwardly until they are braced by boom supports on the rectangular base at an angle over center. This raising of the pivoting booms lifts the mounting arms and watercraft supports to remove a craft from the water and disposes the booms, mounting arms, and craft in a stable, secure over center configuration. Actuation of the double-acting hydraulic cylinder in the opposite direction forces the booms back out of the over center position and lowers the craft into the water.
