I have also been interested to read on madforsailing.com about the self-tacking jib on the new Nacra F18 boat. It would be neat to get this retrofitted to the I20, assuming it worked out.<br><br>I have no problems changing the trap lines to line, but I think the wear/tear/uv/chafe/etc damage would be a problem - it seems (from what I've read) that the lifetime of synthetic trap wires wouldn't be as long as wire.<br><br>Also, I see very few (almost none) catsailors who have a knife anywhere on their boat, much less on their PFD where it could do some good in an emergency (I have one where I can get it 1-handed). I think this would do much more good than changing trap wires, since 98% of tangles are going to be in sheets/halyards, or perhaps trapped uner the tramp or sail.<br><br>Sail fast and have fun,<br>Alan Thompson<br>I20 - San Diego<br><br>
