Hmm, the rig thing is always a question. I bought the boat in 2013 and the previous owners were reassuring about replacement. The question always is what is believable, I have been assiduous about checking the usual culperts with zero signs of corrosion/wear etc. Standing rigging is always a huge ripoff in the marine industry. For my previous boat, I had a crane rigger make the rigging. The cost was 1/3 of the cost of a marine rigger and the quality was there. I just had to wait between their other jobs. I reused the turnbuckles except for the upper ends. I just screwed the new uppers into the rest of the turnbuckle. Could be the same here. Trouble is that I don't know for sure. I'm not planning offshore (getting ready to start construction on new house) but sometimes the Straights of Juan de Fuca right outside the Harbor feel like offshore.
I lost a forward lower on a previous boat. We were racing in approx. 25 knts in a short chop in the South Bay when we heard a twing. 10 minutes later we heard another twing. two minutes later, we heard another twing. Then twing, twing twing and the lower departed. A twing means you are in trouble. We were able to tack before anything worse happened and we retreated with the iron sail roaring. Get the sails down when you hear twing. Look really hard at the emergence of the wire from the threaded end. One trick I've learned since then is to get a bar of bee's wax and melt it into the opening where the wire and threaded end meet to keep the salt water out of the joint.
