Anchor Connections Warning!


Recommended Posts

Here is an image of an Anchor swivel, common in NZ, that has failed due to side loading.

In this case the anchor actually held, but fell off the chain while the anchor was being retrieved!

 

The problem was side load. These swivels are often incorrectly attached directly to the anchor - there should be a few (3-4) links of chain BETWEEN the anchor and swivel, to ensure it can't get side loading and the boat swings around the anchor.

 

Do you have a swivel? Is it attached correctly? Maybe you should check?

That depends on your set-up. All chain can sometimes get away without one. Rope sometimes twists in the capstan, esp laid (like 3 strand etc). Personally, my set-up needs one or the chain twists up. + the rocna anchor often comes to the boat upside-down. If you don't know if you need one, try without, install one only if needed.

Oh, and the DD shaped ones like the top pick above, with bolt between - most are crap, and fail early. KM has tested them and may comment further.

It's pretty clear from this why direct connection to the anchor is a bad idea. My question is why do they appear to be manufactured to allow this?

 

From the images here it appears there is a short slot that will only allow a chain link to be attached whereas the other end has a longer slot capable of accepting the anchor shank. Why are both slots not capable of only accepting a chain link if this is how they should be connected?
