I purchased my j30 with "new" sails that were i think described as only 6 races on them. I always thought the uk tape drive 163 was a little wrinkled to be that new and I always got my ass kicked going upwind. I finally broke down this last year and bought a brand new halsey-uk 155% and the boat really pointed as high and fast as the S2s and even the sport boats. I really performed well on all six races . I won the cup this year in main and jib. I think the boat is not much faster with a spinnaker for the upwind downwind racing but i plan to compete with the chute this season if I can get the crew.
