There is one big issue on this boat, that is how to lift the keel. The original design calls for the use of the main sail halyard and the boom. Obviously, when you do this, one can no longer sail... It is an issue for me, because most of the time, where I sail, you need a shallow draft to launch or come back to shore. I do not need to be able to really sail, but I need to be able to lift the keel enough, so that I can jump in the matter and be able to pull the boat aground or to the slip way and trailer.
So, I put some thought in it and drafted several designs. I could instal a lifting tool on the deck, but it requires some installation and I won't be really able to sail with it in place, because it interfers with the boom. Another design is the one bellow.
In the lower position:
The lifting system is made of 2 sheaves attached to the re-inforced roof. 2 lines are attached to the keel, just above the hull. One winch will pull everything up or let it go down.
