I have a nacra 5.2 with tramp mounted jib blocks(leads) A cable runs underneath the tramp from the fornt to rear crossbeam. The cable comes up through the tramp and then out again. There is a slot in the tramp parrallel to the beams. Since the cable has a lot of slack, the blocks slide inward and outward while sheeting and after sheeting( towards and away from the hulls). How can i fix this? Should i replace the cable with tight spectra line? Is there a way to keep them from moving? Thanks a lot
