I have changed from stainless steel
for both my centre board cables
. The SS became like a hedgehog in no time at all and I think that galvanised would have been similar. The dyneema
is supposed to be good for up to 10 years, so I'll probably change it after 5 to be on the safe side.
There is a large yacht out of Nelson that had all of its standing rigging
replaced with dyneema. We were moored next to it in February in Houhora, it was circumnavigating the North Island as a shake down cruise
after a major refit
. Unfortunately I can't remember its name. But I believe the refit
was done by a major shipyard in Nelson.
