Attempted to tune the rigging on my '81 Catalina 30 tall rig. The owners manual says the lowers should be looser than the uppers- which should be tight. The forward lowes (it has 2 lowers per side, one going forward one going back) were extremely tight. I was wondering whether the wind on the bow would cause that or whether they were truly too tight. Seems I most likely need to loosen them. But. I have no idea how to. They dont have the standard turnbuckles. Heres a pic. Any idea how to loosen these?
Thanks
