Hi Tom, On my 30 MK I (single-spreader rig) there was damage to my starboard spreader bracket and mast where it fastens as a result of my buddy towing the rig through a big cottonwood tree after hauling out in fall 2018. With advice from Dennis Cheuvront on the list here, I repaired the damage by straightening the bracket and fastening a 1/4” aluminum plate over the dent in the mast (and shortening the spreader accordingly). The repair held solid as a rock in the 2019 season and I sailed in some big wind.
Here’s a thread on it in the archives, with a link to some pictures: http://cnc-list.com/pipermail/cnc-list_cnc-list.com/2019-May/207014.html <http://cnc-list.com/pipermail/cnc-list_cnc-list.com/2019-May/207014.html>. My mast has a hole in both sides through which a bolt (threaded on both ends) is inserted, over which the spreader brackets are inserted with nuts to compress them against the mast. I spent a lot of time thinking (and discussing with Dennis) about the function of that bolt and nuts. The windward spreader imparts a compression force on the mast, opposed by the windward lower shroud. Since my bolt doesn’t have shoulders or go through a compression tube in the mast, I believe the purpose of the bolt and nuts is only to keep the windward lower shroud tension from pulling the bracket away from the mast (otherwise it’s only fastened by four screws). The mast is sufficiently stout that the spreader’s compression force hasn’t deflected it in almost 50 years of sailing - it took some tree trimming to do that.
