I am considering adding a topping lift to my COM PAC 23/IV (1/4" line from top of mast to boom end). My 23/IV is equipped with a "pig tail" on the back stay which connects to the boom end and locks the boom in place. The issue I have with the "pig tail" is that I some times forget to detach it when getting underway.
Have any of you installed a topping lift? Any issue that I may not be seeing?
I installed one on my 23 IV. I didn't want the boom falling on my head when I dropped the sail and often not convenient to hook up the pigtail before dropping the sail. Since I had roller furling of the type that has its own internal halyard, I used a 1/4" line through the masthead pulley that normally is used for the jib halyard and through the spare rope clutch for adjustment. It has worked out very well.
Others have used a fixed topping lift with a couple of hook points at the bottom and that has also worked well.
Two galvanized wire clamps, a little tape covering the threads and nuts, a quick bronze disconnect and a piece of ss wire from the back stay to the pig tail on the boom. Why go to the Top`O Mast head?
Hook the Q/D to the boom and drop sail. Hook the Q/D around the back stay when not in use.
Who needs a extra line, a pulley, the weight 'up there'? [for every one pound up there you'll need 15 pound down in the keel]
skip.

Note the cable from stern standing rigging to the boom.
