I am going to upgrade to adjustable genoa leads. I boujght the Lewmar ocean size 0 system (because it was way cheaper than the harken) but the track only comes in 7 ft lengths. The stock T track is around 8ft. I orginally wanted to have a single curved track so I was sure to be able to trim all my old sails. I have a #1, #2, class jib, and a #4. Since it is looking as though I am going to have to go to a split track on each side I need to know where the #4 trims to? I have only used the sail a few times and can;t remember how far back I moved the lead from the #3 position. Any one have any idea?
