Caution etc....
As usual, Dave makes an excellent point about safety in raising a mast.I got a couple of emails that prompt this post. The tripod does not help in the actual lifting of the mast to the vertical position. It's purpose is to steady the mast for side motion. Masts are heavy when you get all that length hanging over the transom so use caution. I put the mast up and down by myself, BUT only after I practiced the procedure with two people first. I placed the second person in the cockpit to watch for stay wires and assist in getting the mast started off the crutch. Only after I had confidence in my procedure did I attempt raising it myself. Even now, I would never step the mast by myself if I had another person around to help. No system is fool-proof and having a second person to help is the safe way to do it.The other email asked what modifications would be needed for other boats. While I can't answer that without knowing dimensions of the boat in question, I can give you the principles of operation. This system works because the rear stancions on the h23 just happen to be about 1/2 way between the mast and the crutch on the transom. This allowed for a tripod pivot point that was ideal. As the mast is raised or lowered, the collar must slide freely up and down the mast. The tripod arms must be the proper length to allow the collar to slide without hitting anthing like the ctutch or mast winch etc.Hope this clarifies and please be careful.
