Posts: 12,310 South Carolina | Hey guys, I'm thinking about addding a self tacking system to my N20. Is the jib a different cut from a non self tacking jib? Also, where should I source my equipment from?
Thanks, Tim The jib is cut different...it's shorter on the foot and may have some other changes to keep the sail area the same. Any F18 self tacking system could be adapted although the system currently in use on the Nacra Infusion is the same system the N20 had on it at the end of it's production cycle. You might even find some success in adapting an F18 jib (that might be a long shot).

This was how everyone did it when the self tacker was first introduced(2001/2002). I have a set of the clew plates which I never installed around somewhere, as well as a used non-self tacking jib and maybe a self tacking one also. The jibs may have evolved to be different now but it wasn't for the self tacker.

I don't like the way the boat behaves with the jib furled and it was easier for me to control with it out. I still have the complete custom Harken set-up for the 20 if you're trying to find one. For jib traveler ,I just used a line from the car through a bullseye to a cleat. Pretty common set-up for self tackers.

Posts: 22 southern germany | sorry, my english is bad. instead of "hide" i wanted to type "hit". both words sounds nearly identical in german. last year i jumped with one of my feet into the jib during a capsize, right in the luff/leach Corner. Result was that the jib traveller was bent and some of the seams of the jib were crushed. My helmsman had replaced the original Polyester rope against a dyneema one.

If the jib traveler car line breaks, the jib traveler car just gets sent to the end of the track, solving nothing as far as releasing the jib. If your traveler car races off the traveler, you're still out the new car at the very least. Solution is to blow the jib if you can (upwind) and spread your arms and legs prior to impact with sails (I know, easier said than done).
The Infusions run a cleat to the base of the spinnaker pole, slightly easier on an aluminum pole than a carbon one. Make sure your pole doesn't twist or your traveler car will be at different positions depending on the tack. The holt-allen and I believe the new Harken self-tacker have spring-loaded adjustable end stop points fitted to the traveler itself, which is nice on the F18 but probably less used on the N20. They've also gone to a double Harken 16mm block on the traveler, for ~4:1 purchase on the jib; the newer sail cuts need to be cranked in tight to aide in pointing upwind.
