A boat lift
canopy comprises a truss type framework with a base frame. Joined to the base frame and circumscribed by it is a tie tube frame, which may be discontinuous. A fabric cover, which in preferred embodiments is decorative as well as functional, snugly encloses the outside of the framework, wraps around the base frame and is secured to the tie tube frame. The boat lift
canopy is held above the boat lift vertical members, which in some embodiments are vertical extensions of the legs of the boat lift. Advantageously, the
canopy is releasably coupled to the vertical members at the tie tube frame, thereby enabling simple adjustment of the position of the canopy with respect to the vertical members, permitting adjustment of canopy overhang or length with ease. Embodiments of the canopy allow adjustment of the length of the canopy by the addition of frame members extending the canopy framework, such adjustment facilitated by the releasable
coupling of the canopy to the vertical members. The framework of the canopy employs an improved truss design such as Howe Kingpost to maximize framework strength, thereby enhancing endurance of the canopy and permitting substantial cantilevered canopy overhangs.
