The supercat pages referred to earlier actually started with a nacra 6.0 jib thread at the following address.
http://www.catsailor.com/forums/sho...ew=&sb=5&o=&fpart=1&vc=1I installed the self tacking jib on my SC-20 with the help of Bill Roberts and Jeff at Endurance Sails and it works great. Downwind the jib actually switches from normal to wing on wing when it is blocked by the main and then back to normal when it needs to. I also have not had problem tacking.
