My jib "tracks" are braided cable run under the tramp from stern cross brace to front cross brace, and they come up thru two holes cut in the tramp, for a length of about a foot. The jib cars then sit on top of the tramp in that open area. On each jib block, I've run a piece of 1/4" line from the bottom of the jib block under the tramp, to the back cross beam, to a turning block and then across the top of the tramp to a jam cleat mounted on the front side of the back cross beam. Thus when sitting to windward I can adjust the leward jib block up and down it's track until satisfied and then just jam it in the cleat. My only question really is, does the changing of it's position really improve boat speed or is it just something to do that has little impact?
