I've just bought brand new North Sail E_Type 6.6 and it came along with 430 Silver series SDM mast and Silver series boom. Problem is that sails persists to have wrinkles in lower part no matter how it is rigged (see images). Having battens (3 lowest ones) really tight removes some of the wrinkles but not all.
To make things more complicated, this is already second sail. I returned first one exactly for the same reason and manufacturer sent new one admitting that sail was incorrectly sewn and/or cut in the factory. It was great surprise to find out this second one to have the same problem, slightly less severe as the first one, however.
I got response today from manufacturer saying that amount of wrinkles is within tolerance and they won't affect performance of the sail. Dealer is very co-operative and says that I can return the sail in case I feel so. As this is my first sail I'm not sure what do.
1) Is this normal "feature" of brand new sail that should be just accepted?
2) Will these kind of wrinkles affect the performance of the sail?
Thank you for any opions on the subject.
