Thanks Matt youve given me a start on this. The stingray Jib doesnt overlap the mast and there are no battens. When I tack I have to keep the jib on the wrong side a little longer to ensure that I complete the turn. I have barber haulers, do you think I could control the self tack with the barber haulers or would that just negate the whole system would you have some photos,diagrammes or links that I could have a look at, I really appreciate your help as the old girl is completely stripped at the moment getting wessystems two pack over the deck and complete reseal of all fittings. I kept a couple of A classes at bay this year but they are getting better and in heavy weather if I can sail solo with a dry hull I'll definately get them.
