Last fall we delivered Wildcat 35 miles in open water to an island regatta. For the entire trip, the wind blew steady 30k with gusts to 40; waves on our hip at 6 to 10 ft. We used our 2004 carbon fiber tape main as our delivery sail. We used it for the return as well, mostly as a weather vane as the storm blew itself out on the first day of the regatta. Other than the paint stains from having used it as a drop cloth the sail looked good and held up fine - LOL.
