sorry its the quality of the pic...it doesnt show some small details

first these damn closed turnbuckles rust from the inside out...so the threads are actually seized by rust inside and very bad looking...on the outside its basically spot rusting...

one thing you CAN notice is the slight bend on the whole "turnbuckle" notice that its bent at the upper "swaged" part...this is caused by weakening and cyclic loads...since the rig at one point was overtressed because one chain plate broke and let go I can only assume the weakest link next inline would be whatever was closest and tightest RIGGING wise...in other words the intermediate stays...

again this is my assumption...they are also 1/4 inch wire...

the uppers being massive held fine...but Im sure the PO had an OH CRAP moment and maybe saw a nice bend in the middle of the mast and quickly tacked over...

there is no evidence of any damage on the mast at all...so thats good
