Rocna Copy Anchors?

[C08]

Looking at anchors-these copies look to be dodgy to say the least. Claims to be one piece construction when you can see it is welded together (not too well by the picture), no metal spec and the test report of a boat pulling the anchor in astern and using the logic that this equates to full power ahead seems a bit doubtful also.

The roll bar looks to be much smaller diameter tubing than a genuine Rocna.

I don't know whether that makes any difference .... the quality of the steel is presumably more important.

On a genuine Rocna the roll bar is a tube, presumably with the intention of increasing tip loading by reducing weight at the back end as much as possible. Also on the genuine article the tube extends downwards to the bottom of the two skegs, where it can be attached by fillet welds rather than the disgusting butt welds shown in the photo.

As you say, it seems unlikely that the material of the copy matches that of the original. Incidentally, the same is true of the Delta copies that are appearing, some of which have even worse welds than those shown here.

Just took delivery of my new genuine 33 kg Rocna and that one looks crap compared !

So your thinking is that the fake Rocna is using a solid bar of round steel rather than a hollow tube? I had assumed that the fake was simply using smaller diameter tubing but you could well be right.

You're certainly right about the Rocna having nicely welded tubes into lower skeg. However, there is a slight annoyance with the opened ended tubes in both my 25kg Rocnas and that is that when anchoring in mud, the mud gets pushed right up into the hoop until it meets from both sides at the small hole drilled at the top of the loop. I usually try to clear the mud out when I get back to my home marina but on a cat that's means quite an effort to get the anchor onto the pontoon so I can get the hosepipe on it.

Once I can get some pressure I can squeeze out a foot long sausage of black stinking mud ...... it's quite amusing if rather a hassle.

I've wondered about driving a couple of bungs into the tube ends or similar but I've never bothered. I don't actually know if the mud would degrade the galvanising but that is my only concern.

Where do they sell these copies?

 

[C08]

Sold on ebay us about 1/3 the cost of genuine anchors.
