Galvanized Standing Rigging: Is it Safe? How to Know?

[fish53]

Thank you, I did check out the Davey catalog recently and interestingly they carry galvanized chainplates, a lot of what they carry is available in galvanized and gunmetal (bronze), their prices are a bit high though, I hate to sound like a cheapskate but I'm trying to do things myself as much as possible, I hate to be dependent on others, especially when so much can be accomplished by acquiring a set of simple skills.

You, sir, are an anachronism and an outright embarrassment to the modern concept of checkbook sailor!

Gee, I've been an embarrassment in one form or another for over sixty years, can't change now. At least this is one arena were I don't feel the embarrassment.

Takes one to know one.

Just a quick question. I notice a couple of mentions of using brass or stainless steel chainplates with galv wire rigging. Wouldn't this cause galvanic corrosion, similar to what happens when a stainless swivel is used on a galvanized steel anchor and the metal of the anchor begins to rust? I would think the interface of the socket or splice would be at increased risk of this corrosion...

Thoughts?

Here's a short discussion of metal compatibility...

Note Davey is mostly concerned with dissimilar fastenings. as galvanic corrision can only be present in an electrolyte - fastenings are most at risk when the hull material absorbs water and produces an electrolyte which creates electical flow that eats up the dissimilair metal.

So, galvanized wire in contact with the end of a BRONZE, not brass, chainplate, or SS chainplate is a minor issue, compared with using the wrong type of fastener to secure the chainplate to the hull.

BTW, wikipedia has some interesting disscussion and examples of galvanic corrision with dissimilar metals
