A boat lift canopy comprises a truss type framework with a base frame that may be rectangular, comprised of side and end horizontal members. The framework is comprised of channel-ridge interlocking extruded components, enabling easy construction with minimal or no welded parts. Joined to the base frame and circumscribed by it is a tie bar frame, which may be discontinuous. A fabric cover snugly encloses the outside of the framework, wrapping around the base frame and secured to the tie tube frame with canopy ties. The boat lift canopy is held above the boat lift by vertical members connecting to supporting legs. The canopy is releasably coupled to the vertical members at the tie tube frame, facilitating adjustable extension of canopy overhang or length by the addition of frame members extending the canopy framework. The framework of the canopy employs a truss design such as Howe kingpost to maximize framework strength to support substantial cantilevered canopy overhangs. Modular, easily assembled components enable provision of the canopy as a kit of components for user assembly.
