My adventures and probably misadventures in building "Vertigo" a custom racing sailboat

Let The Keel Begin!
Well, today I got to do a bit of work on the boat. I put a couple more coats of gray primer on the hull. This means I now have 4 coats. I think I'll add one more tomorrow.
I also started my journey toward having a keel. The keel for this boat will be a high aspect ratio wood cored carbon fiber fin with a 600 lb lead bulb at the end of it. The foil shape will be the NACA 0012 which from what I've read is a good all around foil for this kind of application. The chord will be about 18 inches with nearly 5 feet of foil between the bottom of the boat and the bulb. When finished, the fin should only be about 2.25 inches thick.
For a core, I'm using laminated clear red pine planking. The core will not be providing much structural strength. It will serve mainly as a rigid spacer between the outside shell of carbon fiber which will bear the bulk of the loadpath.
Tonight I laminated 3 sheets of pine to make a core blank that is 2 inches thick. I've weighted it down on the shop floor while it cures. Hopefully the floor is nice a flat so that the core blank ends up true!
This boat has never been built but what I'm hoping for is that if an old T-bird and a sexy little I550 got together, this boat would be their love child. For more info, check out the history section at the begining of this blog.
The boat is 26' feet long and 8' wide. With it's hard chines and tons of sail area it should go very well to windward--even in light air. I'm planning on a huge asymetrical chute for downwind which with the boats flat botom should get it planing very easily. Hopefully it'll be fast and fun!
