Re: new 120% genoa
Traditionally laminate sails hold a good shape for much longer than Dacron. Dacron while it looses a good shape quickly continues to hold some shape for longer.
Basically Dacron will be bagged out after a year or so of hard use. While a laminate sail will continue to look fine. Three years down the road however the Dacron will still look bagged out but usable, while the laminate pretty much has to be replaced.
