My 70's Heritage One Ton had rod rigging. It had been replaced in the mid 80's, so it was about 20 years old. The P.O. caught a gust from starboard, heard a gunshot, and the whole rig came down in a spectacular crash with the mast breaking off at the gooseneck and falling over to port. Fortunately, no one was hurt. Basically, the P.O.'s wife told him he was all done, and I ended up with the boat.
Turned out that the headed end on a D1 had parted and a turnbuckle had parted - both to windward when the event happened. There's no way to really determine which failed first. We were able to salvage the mast and boom. The furler, hydraulic vang, hydraulic backstay adjuster, jib, main, port lifeline stantions, and most of the running rigging were history.
With some input from Charley Morgan (who built the boat), we were able to splice the mast and get her re-rigged. Getting the rig back up (sans sails, etc) using wire cost somewhere in the neighborhood of $16K. The estimate to re-rig with Navtec rod was about $25K. We went with wire due to cost, servicability, and "piece of mind factor".
