These sails are the first goya sails to come along with the first real goya boards (not under the Fanatic logo and shaped by Sebastian Wenzel). So tracing back to 2005 -2006 I guess... a long time. So maybe you got a good price..This was way before Jason Diffin started doing the goya sails... as a matter of fact i can't recall who designed them. Nevertheless I am sure they are good and still doing the job. Yours looks in good shape and promising for lots of sessions. Hope this helps.
