Hello,
you originally asked about rocker. It's a very important curve. Yours looks allitle flat forward and maybe too curved in the last 18"...or did you invent a most superior rocker?
It would be cool if there were a data base of the various rocker curves of existing cats. A data base of the rest of their features like mast height, hull volume would be good too. Guessing that the Texel guys must has some of this data to create their #s.
it's just that a visual curve is good as a spark to the imagination. Maybe if we posted pictures of the side of our hulls we could vectorize the profiles and get the rocker curves.

Because we use alot of it, i would shape the hulls from styro to test different hulls.
the whole project is for those with free time and money to play with.
have fun with it.
