I'm thinking about curved centerboards.

I had Phil's Foils make me a half plug for a centerboard that I made a mold from and I am happy with the boards that come from it. But I thought that curved centerboards might make a good over the winter project for me. So I've got the centerboard plug mounted on the strongback with a curve added (shim?) and the radius is 200cm.  I guess I'll see how it works.
