As long as we're talking about interesting sails, how about
interesting sail materials, not to mention cheap: Tyvek, the 10' wide
super-strong stuff they wrap new houses in.
http://www.boat-links.com/Tyvek/
has info on how to do it, and you can often get it free.
He uses it for his sails and talks about a 40-footer with 300+ sq. ft. sails of Tyvek. I also referred a friend's brother to this and he has made sails for a homemade dinghy, which might be considered the world's cheapest boat. Don't know how they're working out yet.
At the least, it may be good for dinghies, practicing sailcutting or as a quick replacement. And if it blows out, you're only out a couple of bucks. Start saving those FedEx envelopes.
Of course, you'd wanna change your boat's name to "Tyvek" to match the sails, but DuPont might pay you for it. ;)
Interesting idea, anyway.
