Hello,
I am a new sailor and new to building boats.
I was bitten by the sailing bug (or rather, the infection became acute) and since then have been getting more and more deeply into it. I've taken sailing lessons, read a lot of books (histories, sailing manuals, design books).
I had a problem when I started: I wanted to sail after I took my lessons but had no boat. And no where to store one.
But I did have 2 canoes. So, after vowing to my wife I would make no permanent modifications, I designed a set of ... prostheses?... that turned the canoe into a sailboat. Mast of plumbing PVC, Sails of blue tarp, outriggers for stability (oak struts, PVC floats), a larboard and rudder.

On its maiden voyage it reached and ran downwind well. It would not point at all. I determined the craft had a bad case of lee helm, because the nose of the canoe was rising up and moving the CLR aft too far. I altered the rudder design (deeper), the daggerboard (deeper, canted back) and added ballast to the nose of the canoe on my second try.
It sailed VERY well.

So now I have a boat, with the attendant satisfacion of having designed many of its components myself. So now I'm going to build another.
I am planning to take a 17' Aluminum canoe, cut off the stern and install a transom, and install a retractable daggerboard with a weighted bulb on the end. I may be bouncing some ideas and questions off of the good folks here.
I look forward to some stimulating conversations.
regards,
