From all the above posts about which shrouds and stays have had problems, you could surmise that if your recently purchased older boat cannot document when and what was done as to the standing rigging (mast, shrouds, stays, and other wire/rod) then it would be prudent to get it changed.
- - Wire/rod terminals can only be accurately check by using dye penetrant to find hairline cracks. Worn turnbuckle/chainplate pins and clevis pins can only be accurately inspected by removing them. Studs, terminals, rod balls, etc. also need to be actually removed to be totally inspected.
- - And if you are going to invest in all this removal
you might as well go ahead and replace the old wire with new wire. The wire costs are the least of all the expenses involved. Chainplates are a major problem as like an iceberg, most of it is below deck
level or hidden behind interior
paneling. Water leakage down through the hole in the deck-edge for the chainplate can easily allow intragranular corrosion
to attack the chain plates. A failed chain plate
is not something that can be "field fixed" while underway in big seas.
- - The standing rigging along with the mast
are a major safety
system on a sail boat - witness the teenager who lost
her mast in the southern Indian Ocean
- - There are new materials and techniques available today with regards to wire/rod and standing rigging and if you are intending to cruise
the oceans and seas it it will worth the time and money
to know that your mast and rigging will not come down in a blow. Over 10 years of ocean use - and a unknown history
from the previous owner = replace the standing rigging wires, etc., and really inspect and test all the components.
