A travel lift or travelift (also called a boat hoist, boat gantry crane, or boat crane) is a specialised type of crane used for lifting boats out of the water and transporting them around docks or marinas. These cranes allow boats with masts or tall superstructure to be transported around hard stands as the tall upper structure can pass through the open end of the crane framework before lifting and after setting down. There is also an Amphibious version that can be lift the boat directly from the sea.
