(39) FIGS. 23A-23D are perspective views of an implementation of a retractable canopy 20 for a watercraft lift 22. The retractable canopy 20 includes a fixed boom 24 extending from the watercraft lift 22. A movable boom 26 is supported for rotational movement by the watercraft lift 22. An actuator 28 (shown in FIG. 23C) is operatively connected to the watercraft lift 22 and the movable boom 26 to rotate the movable boom 26 between a first position as in FIG. 1A and a second position as in FIG. 1B relative to the watercraft lift 22. In the first position shown in FIG. 1A, the movable boom 26 is spaced from the fixed boom 24. In the second position, the movable boom 26 is adjacent to the fixed boom 24.
(40) The retractable canopy 20 further includes at least one first linkage 30 extending between the fixed boom 24 and the movable boom 26 and at least one second linkage 32 extending between the fixed boom 24 and the movable boom 26. At least one first strut 34 is rotatably supported by the at least one first linkage 30 and slidably supported by the at least one second linkage 32, as further described herein. In one implementation, the retractable canopy 20 includes at least one second strut 36 rotatable relative to the fixed boom 24 and at least one third strut 38 supported by the movable boom 26. A cover 40 is secured at a first end 42 to the fixed boom 24 and at a second end 44 to the movable boom 26.
(41) When the movable boom 26 is in the first position, the fixed boom 24, the movable boom 26, the at least one first strut 34, the at least one second strut 36, and the at least one third strut 38 support the cover 40 in an extended configuration above a watercraft area (e.g. area of boat 46) as shown in FIG. 1A. When the movable boom 26 is in the second position, the fixed boom 24, the movable boom 26, the at least one first strut 34, the at least one second strut 36, and the at least one third strut 38 support the cover 40 in a retracted configuration adjacent to the fixed strut 24, as shown in FIG. 1D.
(42) In one implementation, the retractable canopy 20 further includes a support post 48 coupled to the watercraft lift 22, wherein when the movable boom 26 is in the first position, the movable boom 26 contacts the support post 48, as best shown in FIG. 1A. Further, the retractable canopy 20 includes a support rod 50 coupled between one of the at least one third struts 38 and one of at the least one first linkages 30. Preferably, the at least one first strut 34 is also rotatably supported by the at least one second linkage 32.
