J/30 Class Association Forums J/30 Forum The Boat, Sails and Equipment Will This Sail Work?

So a kevlar/mylar main in great shape has basically fallen into my lap for very reasonable money if I want it. The catch is that it comes from a J/100. The foot is 13' 2" and the luff is 37' 9". Should I buy the sail? Will the cut and dimensions work for the j/30?

Thanks!

Josh
