To be candid, I’d say no but thats ok for us to say, your the one who would have to spend the money!
I would say that the sail’s bolt ropes have shrunk and the sail is so out of shape from being old,Id put at more than thirty years old from here!
You could get an estimate from a sail maker for repair or for new but I would say you maybe spending on old when it could go towards newer.
Can I ask what you will want from another sail,race or just a sail about,reefs or no? Older race sail or something else.
