Skiffs & Dinghies profiles & dimensions database

Hello,
I would like to study different skiffs or Dinghy daggerboard performances and I'm searching for 3D models or at least detailed profiles & dimensions from daggerboards of :

• RS 400/700/800
• 49er / 29er
• VX Evo
• I14
• Cherubs
• First 14
• ...

Any suggestions on how I could get this?

 

I went and checked a few class rules to see what they said about board shape. So far, I only found some for the 470, which were not terribly specific except for which part of the board should be flat.

A leading edge cross section that's a half an ellipse is probably pretty good. Or maybe parabolic. I would be quite surprised if a fair number of 470 boards have elliptical leading edges as far back as permitted, and straight taper as far forward as permitted for the trailing edge. Presumably, there would be a small radius where the taper starts, and the trailing edge would be squared off at some reasonable thickness. I'll bet a bunch of other class rules require boards that are mostly flat like this.

Other than that, I haven't seen anything yet, though I'm sure a fair number of daggerboards are NACA 0010 or 0012
