Both the Capri-18 and Capri-22 share the same spreader assembly. You'll notice the side stays are behind the mast slightly. This allows you to remove the back-stay to lift the boat with a lifting harness. The mast won't tip back or forward. After your done lifting, re-connect the back stay. Nothing to it. My boat is kept fully rigged, I just push the boom over to the side and secure it to the side stay with a bungie cord,(my boom is supported by a boom-kicker, but that just makes it easier). I reconnect the back stay and I'm ready to go sailing. The pictures I posted was before I got the hang of it, and was learning how to secure all the lines to keep is level,(lifting line from the keel to the lifting ring, 2- 5/16 lines from the lifting ring to the cleats on the side if the cabin top, and 2- 3/8 lines from the lifting ring thru the rear cockpit scuppers and back around to the rear deck cleats). This is the same method I learned from the Capri-22 folks at the yacht club.
