Keels often use NACA 63 (or even 64-66) series, which have lower drag at small angle of attack. standard NACA 4-digit 2D airfoil.

Například profil označený NACA 6318 má maximální prohnutí 6 % nacházející se ve 30 % hloubky profilu a dosahuje maximální tloušťky 18 %. Since you have a catamaran with daggerboards, an asymmetric profile would be clearly better providing low drag bucket even at normal beat angle of attack. Reading aviation litterature helps a lot so far. I hope it helps.

Change # Points to “60” and Point Size to “4” so that the points are clearly visible. 2. I understand, for symetrical foil, ratio is sufficient to modify one profil in one other (try with the NACA 0012 to 0015) All structured data from the file and property namespaces is available under the Creative Commons CC0 License; all unstructured text is available under the Creative Commons Attribution-ShareAlike License; additional terms may apply. 813 0 obj <> endobj From Wikimedia Commons, the free media repository.
