Arvel Gentry, the author, wrote plenty of fascinating articles on sail theory for laymen (and more technical work as well). I suspect his seminal work was How Sails Really Work (1973)-- https://web.archive.org/web/20120308100740/http://www.arvelgentry.com/magaz/How_Sails_Really_Work.pdf https://web.archive.org/web/20120308100740/http://www.arvelg... . You can find many more of his other articles at his archived website/blog[1] or this website[2] that was created posthumously.
