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

I am interested in any info found on the web about j30 rig tuning or has anyone added runing backstays with any luck in speed improvment? any info will be helpful.

Keep in mind that running backs aren't class legal. Also, in theory, they fall into the
category of things which should generate a PHRF penalty.

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!!

I don't believe there's any J/30 that came with runners on delivery. They may have been added later, or if a mast was replaced, the new mast could have had them.

All the rig tuning guidelines are available on the J30 website (www.j30.org). You'll find the class rules and a tuning guide from Banks Sails.

Well, Hull 3, which still has the original stick, has the slots up top for the runner t-toggles. There's some wear on the slots, so
presumably someone played with them on that boat at some time. By the time we got the boat,
the then current owner didn't have the runners, and couldn't recall if he'd gotten then when he bought the boat used, more than ten years previous.

In the archives there's a photo of hull #1, Warwhoop, on her 'maiden voyage' with runners installed. John Kolius sailed her to 3rd in class in the '79 SORC, back when the 'OR' meant ocean racing. By the time we borrowed this boat for the '88 midwinters (remember them?) the runners had long since been removed. Even frac J/29's rarely use their runners.
