Abstract
A watercraft lift with hydraulically actuated arms which self-installs a fitted three-dimensional boat or other watercraft cover on a powerboat or other watercraft. Control logic allows for cover operation only when the lift is raised, and has a single control for both the lift and cover system. A spring-tensioned roller keeps the cover tight and self-rolls the cover on the roller when the actuated arms are pivoted forward. The roller is hidden behind the watercraft when in a “cover-on” position.
