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!
