The devices that are described hereafter are called boat lift or shiplift. A boatlift and a shiplift however can also be a device on a shipyard to dry dock and launch ships for repair and or newbuilding.

A boat lift, ship lift, or lift lock is a machine for transporting boats between two different water heights, and is an alternative to the canal lock and the canal inclined plane.

It may be either vertically moving, like the ship lifts in Germany, Belgium or "Les Fontinettes" in France or the Anderton Boat Lift in England, or rotational, like the Falkirk Wheel in Scotland.

The world's highest boat lift, with a 73.15 metre height difference and European Class IV (1350 tonne) capacity, is the Strépy-Thieu boat lift in Belgium.

The ship lift at the Three Gorges Dam will be able to lift vessels of up to 3,000 tons displacement.^[1]
