Assemblies for boat lifts

A kit of parts for a boat lift, comprising:

• eight elongate members;
• an elongate beam;
• an elongate cable winding shaft;
• a cable;
• and
• a boat cradle,
• wherein the kit is configured to be assembled as an assembly of the boat lift that includes:
• a frame including the eight elongate members, the frame extending from a bottom of the frame to a top of the frame parallel to a vertical axis, the frame including:
• four of the elongate members positioned to be elongate parallel to the vertical axis to define a first pair of vertical members and a second pair of vertical members;
• another four of the elongate members positioned to be perpendicular to the vertical axis and coupled to the vertical members;
• where the first pair of vertical members and the second pair of vertical members being adjustably coupled to at least two of the four horizontal members to adjust a spacing between the first pair of the vertical members and the second pair of the vertical members;
• the beam positioned to be elongate perpendicular to the vertical axis and above the four horizontal members relative to the vertical axis, the beam being attached to the first pair of vertical members or to the second pair of vertical members;
• the cable winding shaft positioned to be elongate perpendicular to the vertical axis, and rotatable relative to the beam;
• and
• the boat cradle being coupled to the cable winding shaft with the cable such that the cradle can move, by rotation of the cable winding shaft, up and down parallel to the vertical axis and relative to the frame.
