: I have no info on sailing rigs, but if you (or anyone else) needs
: quantitative foil data, pick up a copy of "Theory of Wing Sections,
: Including a Summary of Airfoil Data" by Abott and Von Doenhoff, Dover
: Editions (around $20). The appendices include x-y data used to draw over
: 70 types of foils, symmetric and nonsymmetric, plus performance data in
: the form of lift and drag curves as a function of angle of attack,
: Reynolds number, etc. This is the bible of standard NACA foil shapes used
: in low-speed applications - e.g. my brother uses it for windmill blade
: shapes, you could use it for hydrofoils, rudders, RC airplane wings, etc.

: There's enough theory in the first half of the book to figure out how to use
: the performance graphs, but many just pick a foil based on a pleasing
: shape and use the x-y coordinates to draw the section for construction.

Got a copy of that book, I too recommend it. I just don't know right now which box that book is in .
