A lot of "Build Log" for Hulls of any kind, few "Build Log" for sails and none dedicated to "Sail drawing". I decided therefore to presents a 7 pages paper (PDF) describing the method I use to DRAW my Class M Sails.
Why Class M ?
Because is more complicated then others.
Frank Russel, kindly enough, issued on the Net a set of Class M Sail forms with data ready to be copied and built.
Myself, I'm just explaining what happen before the drawing paper template is ready.
The document can be free downloaded, see below.
Hope will not be not too complicate to read it, drawings are reporting major data and text try to explain how it is done step by step.
Only Rig A is presented in the paper since Rig B and C follow the same drawing technique.
Any questions ? Do not hesitate
