Since there has been so much talk about design, can anyone suggest reading
material on the design of sails on sailboats, and hang gliders??

I remember Marty mentioning something about modeling books/magazines having
topics on aerodynamics.  Marty, do you have a list that I can use to find some
of the issues of these.

Right now, my main objective is to understand the whys, wherefores, and so on
about the camber induced in sails.  I know the purpose is to generate an
airfoil, I just want to know more about it.

Please reply via the newsgroup or send mail via compuserve cause I can't get
mail from the net on this machine yet.  My compuserve address is 
73110,562@compuserve.com.

Thanks, Sam.

I'll recommend:

C.A. Marchaj, Sailing Theory and Practice, Adlard Coles Ltd,
ISBN 0 229 64253 5

"A scientific analysis, with 335 drawings and photographs
of the aerodynamic, hudrodynamic, and other design factors
which define a yacht's behavior"

A reader of rec.kites who understands aerodynamics recommended "The
Illustrated Guide to Aerodynamics" by H.C. "Skip" Smith. The first few
chapters provide a great deal of insight into how things work. There
are also chapters on control and stability. Reading the book caused
several light bulbs to go on above my head. I've got some serious
experimenting to do...
