My current jib (on a roller furling) on my 1980 O'Day 30 is tearing badly and needs to be replaced. I would prefer buying a used on as opposed to spending $1500 on a new Doyle sail. Any advice on who to buy from and how to order. I do not know the exact specifications but I would prefer a 100% jib. Any advice is appreciated.
