Quality of Tayana V 42 Rigging/Metal

[Brion Toss]

Hello,
The bad news is that the metallurgy on just about everything is not trustworthy by this time. The good news is that it will be obvious if it is bad. If the boat is still in the Bay Area, call up Guy Stevens to have him inspect it (and everything else). He'll be able to give you a realistic, reasonable assessment of condition, and what it might take to replace things.
Even with bad metallurgy it can take many years for things to get scary. But many years have passed. And it is possible that your boat got a good batch, or was in a window of time where they used great hardware, well-bedded. Not likely, but possible.
We have worked on several of those boats. Wonderful boats, with that Achilles heel. Really spectacular failures at times.
Fair leads,
Brion Toss
