I bought a 331 five years ago built in 2000 that had the original standing rigging which, in the surveyor’s view, needed replacement. The seller and I agreed to split the cost and that, I think, was £1500 each but it’s easy to get an estimate. The masts removal and replacement was £480, so not exactly a low cost exercise.
There is a good article in the latest Yachting Monthly,(September) page 44, Practical Seamanship, Number1, entitled Rigging Checks. It concludes: “Checking rigging is not a function of a specific amount of time, rather the real-world conditions your boat has experienced.”
