An interesting post.
My 331 Good Dog is 2005.
My insurers (Admiral) have told me they want a Standing Rigging Check by 2020 – so 15 years.
I am having one done now at Ardfern Boat Yard and await the outcome.
What I am not sure is what is within the prices above – just the shrouds / forestay – or every piece of metal – e.g. the pins on the main and mizzern sheets.
One bit of running rigging that has got worn on my 331 is the Triatic Stay (rope connecting the top of the Mizzern mast to the top of the Main mast).
I will keep this post “posted”!
