I just came back from the sailmaker. As I had no news, I said that I was coming this afternoon to take the sail back, even if it wouldn't be repaired. So they do it but no quotation. They haven't ever cut a skiff sail. . . . they took no dimensions. . .
Two months ago, I've asked to Laurent Thouvenin (who brought back Primalscream to France) to make a new mainsail for solo handing whit a light jib of "Défi Français 1992" I had. The tissue is as new. I just call him to ask for a "normal" mainsail. I think it's - for the moment- the best solution and will wait for solo handing.
Thanks for all answers guys!
I'll post photos as soon as I'll get the new sail.
