A heavy duty low-profile watercraft lift (10) for lifting small watercraft into and out of the water adjacent to a dock (12). The lift (10) comprises a single heavy-duty column (22) having a winch (28) mounted on the top thereof for raising and lowering a carriage (26) that is engaged with a track (32) formed on the column (22). Adjustable arms (72) and rails (74) on the carriage (26) enable adjustment to fit a watercraft. Opening (108) allows a pin to be inserted therethrough to hold the carriage (26) in a raised position. The winch (28) can be mounted to any side of the column (22) to meet the needs of a particular installation. The lift (10) of the present invention provides a compact, efficient, and visually appealing dockside lift.
