Hi All,

I have attached a photo of how the anchor was attached from our survey. We had not modified anything other than replacing the chain in October. We are 100% certain that it was not stolen, other than by the water. We tied up the bridle to the gangway cleat so we know it was stowed when we left.

We are very confident that the anchor eyelet fractured or broke completely during the trip from Aruba to Curacao.

We did not mean to bad mouth Rocna just wanted to know how common a problem it is. I was surprised to find out about the West Marine Rocna recall that took place just a short time before the anchor was purchased in 2016.

Does Rocna's handling of this remind you of the way Ford handled the Pinto, whereas WM is more akin to the way Johnson and Johnson handled the Tylenol poisoning problem?

Thanks to all for all the input on the anchor and anchor setup.

I don't see that this photo shows the critical elements... those that connect the chain to the anchor. And for that matter, if you changed chains, then the connection would not be identical to that in the photo.

And agint, as I recall, the issue with the Chinese Rocnas that were recalled was use of a lower grade steel, one that was less stiff than the specified steel... and such steel would be more malleable and less likely to fracture catastrophically.

I'm not convinced that the anchor broke. But you are and I doubt that any further discussion will change your mind, so what would you like to achieve in this thread?

I do agree that it is very hard to believe that the anchor broke.. I have a Chinese 33 kg Rocna. If I remember right it was installed 2008. I did regalvanized the anchor after app. 10 years of anchoring. I estimate that we have spent at least 2200 nights anchored since new. Chain is a Duplex stainless chain that was installed already 2003. It still look like new. The first years I used a galvanized shackle. Changed that to stainless steel shackle as the galvanized shackle was corroding badly. Strange enough, I do have very little if any corrosion between anchor and stainless steel shackle.

When the chain was new 2002 I had to do send in a piece for a destructive pull test. Last year I took off another 3 feet and sent to the same company for a follow up test. The pull test showed identical results.

Is it just me, or does that anchor look over-stressed. Distorted slot (sharp angle at front lower corner, stretched at rear and thinned out above at rear.

I'd suggested it's been badly overloaded at some time and the slot severely weakened.

Hi All,

I understand that many posters don't believe that the anchor could fail as described and that is fine. I am open to any other suggestions other than it was stolen, which it was not. That it was lost before sailing, which it was not. It was stored as shown in the images while sailing and 2 hours later it was gone leaving behind the shackle and chain.

The only thing I am trying to accomplish is to find out how frequently this has happened and based on the images what I may have been doing wrong so that I don't repeat the same mistake and lose another anchor while sailing on a day trip. Or if there might have been something wrong with the Rocna anchors.

I have provided all the information I have and no I was not trying to get Rocna to do anything as others have suggested. I am a realist and know that few companies would step up in a situation like this. With that said I would like to recognize Echo-Tec for standing behind there warranty even after it expired. I tried to order a replacement part and they said that they would honor the warranty even though it had expired 2 months earlier and all I needed to pay for was shipping. Not often a company would step up and offer to replace something these days.

I keep going back to the pic of the shackle pin that looked like it had backed out, but maybe the OP has already ruled that one out.

I think it’s always possible for any piece of metal to fail if it’s been stressed prior. If you didn’t own the rocna since new then maybe the slot was elongated and overstressed.

That said, your original pics show a different shackle (stainless) left behind on the chain than on your rocna and chain setup (galvanized shackle) you just posted a pic of.

How come?
