Is it time to replace this anchor shackle?

I pulled this off my anchor thinking it needed to be replaced. However upon closer inspection, the material seems to be intact. I'm sure it doesn't have 100% of its original strength. I'm tempted to replace it, since it seems most shackle failures are at the pin, and the pin is the only thing that is rusted on this one. Or should I be saying "nah, its fine!"

If you have to ask, just replace it. Very inexpensive item.

Re: Is it time to replace this anchor shackle?

My whole shackle on the rope rode end looks like your pin ...... actually worse that your pin but so far so good. I take a wire brush to it every now and then to see how much metal is left

I probably need to saw it off though and replace

I wish they were $2.50. A 3/8 Crosby G-209A is $12.50. Replace it.

Yes because:

and
Every time you go to sleep you'll worry about it

Re: Is it time to replace this anchor shackle?

It is cheap enough that you shouldn't risk it, replace it! However I would keep it as you may well find a use for it later; on something not quite as important as your main anchor.

Yes-but a Crosby is the brand to buy for tested quality IMHO. / Len

Nobody cares that they saved $12.50 when they wake up on the beach. I wouldn't bat an eye if it were $22.50 and required yearly replacement.

Re: Is it time to replace this anchor shackle?

Yeah my suspicion is that it should be replaced - and they are not expensive so I'm not balking at the price. It was more of a general feel from the sailing community to see if a little rust on the pin is something to be worried about or not!

Re: Is it time to replace this anchor shackle?

Why not clean it up a bit, then see if you still feel tempted? It is not a bad thing to be easily woken at night--a time to check on things. Devil's advocate here, really, because me, I'd re-purpose it. And follow everybody's advice for a tested shackle, too. But that's because then, it'll be right for a long time to come. Fwiw, we use lanolin on our shackle pins, and they're easy to undo because the threads don't rust.

Re: Is it time to replace this anchor shackle?

We would also replace it....

And, you might wish " mouse " the pin to shackle with some safety wire.

No chance of it backing out .

Re: Is it time to replace this anchor shackle?

There are various alternatives on what constitutes an unacceptable amout of loss. For anchor chain it depends on factors such as whether the chain is oversized, but a 10% thickness loss is often quoted.

It does not look like the shackle pin has lost much material.

However, it is silly to make a shackle the weak link in the system. Given the potential side loading, and the cheap cost of this component, routine replacement seems sensible.

The resolution of the photo is not great, but it at least looks like this shackle has a rated SWL

As a replacement, one of the G8 rated shackles is worth considering:

Van Beest Super Shackle
Crosby 209A
Titan black pin

Are some of the commonly available options.

Re: Is it time to replace this anchor shackle?

It probably will last a while longer.

Incidentally, if you wish to get longer life out of these shackles, assuming you bought a good quality Sheridized one in the first place, cut a small length of stainless steel tube that will fit over the pin but not too tightly, and in between the jaws of the bow.

That will take 50% or more of the wear--and your shackle will last a lot longer.

Having a little nail varnish on the thread before you tighten the pin is a good idea too--since we can no longer get white lead or red lead primer.

THEN mouse the shackle pin with stainless steel binding wire.
