New to forum and to trawlers but not to occean. My wife and I bought a 1980 49 Grand Banks this summer and we are slowly getting the systems up to par. The mast and boom are in great shape and I was trying to figure out structurely including stay wire system what the safe lifting capacity is. All the rigging is new and rated to 1200lbs working load. The stay wires are 3/8 stainless in great shape also.
