J/30 Class Association Forums J/30 Forum Racing Tools and Techniques j30 rig tuning guidlines

I raced on a 30 back in the early 80's, I think it was hull #46(could be real wrong). We had factory installed runners, couldn't use for class racing but we did allot of PHRF then, they did not seem to make any diference to performance. THe J-30 rig is kinda stiff for runners and the windage is not worth the minor if any speed increase. Hope this helps!!
