I would not do a dac/mylar laminate, like Norths Norlam or equal, these do not get the mileage that straight dacron gets, or for that matter, My Ullman Fiberpath is doing better after many more tacks, miles etc than the Dac/mylar sail I have.
I would look at a sail made with Dimension Polyant in the DP or GPL cloth, may be equal to a triradial pentex mentioned earlier. Or Ullman has a CAL sail, a panel sewn scrim laminate with a cost just about a GOOD dacron sail. I paid about 1700 for a 140, a dacron would have been about 1500. I could find some lofts as low as 1000 in dacron for my boat. My Fiberpath was $3K-3500 IIRC. $$ are shown only as examples, my boat is 5' shorter.
I use the CAL as a daysail/cruise sail, and occasional race, pulls really well, better than a dacron, not as good as my FP tho. From a cost standpoint, the CAL or a DP/GPL/pentex tri-radial sail frankly would be your best $$ options.
I do know one person with a sister boat to me on the east coast, that looked at Bacon's website almost daily, after a few months, did find a pentex sail in great shape for about half the cost of a new on.
She drives me boat,
I drives me dinghy!
