Righting swivel for Rocna anchor

Can anyone tell me where I can locate a vendor for a so-called "righting swivel"? It looks like this:

That's clever. It's obvious how it works. Many here could be interested in this.

Question though is why is it aimed at the Rocna?

You're right Eric. That could well be the perfect answer to the fact many anchors occasionally insist on coming up orse-about...and no loss of strength, (as long as that swivel join is robust enough), or anything to catch on the bowsprit either. Even Marin would be hard-pressed to find fault...

Actually, it occurs to me, that really, with that curved shape making it virtually certain, if one paused a sec at that point of the curve, that the anchor would come up the right way anyway, that a swivel at the chain end is virtually superfluous, wouldn't you think..?

might be my ignorance talking but does that replace he Manson Supreme rock slot? I have the Manson and love it. Never had a problem with it coming up bass ackwards or orse about but I'm sure that will happen to me down the rode. How much does it swivel? I'm interested to learn a little, not trying to be too funny.

You can get something similar from Anchor Right called a flip link.

Haha Peter ....
Looks like your guys are already on top of it.
No need for the bling either.
Not superfluous at all. When it comes up 180 out the bent bar needs to rotate .... no I think I see your point Peter. The bent bar will just rotate the chain between the bow roller and the gypsy. On some boats that distance could be short and the swivel may be needed.

Rossigal,
Can't see that it has anything to do w the rock slot.

I'd be careful about getting the wrong model. As all salty dogs know, anchors from the southern hemisphere (SH) tend to favor the CCW (anti-clockwise for you non-Yanks) rotation when retrieved. Obviously, northern hemisphere (NH) anchors rotate the opposite direction. The SH model compensates for this CCW bias and works great on SH boats. If you mistakenly install the SH model on a NH boat, the anchor swivel may be grossly aggravated.

Swivels
Swivels are a popular accessory helpful in reducing rode twist and allowing
the anchor to be rotated upon retrieval. A swivel should be rated to the
breaking strength of the chain (not the working load), and care must be
taken to avoid cheap, poorly engineered, and badly built designs.
When installing, be sure the swivel cannot be subjected to a veering
load and can rotate properly. We do not recommend attaching the fork
of a swivel directly to the anchor shank. It is safer to put a few links of
chain between the swivel and the anchor. If this is done, an articulating
“ball-and-joint” design is pointless, and an in-line rotating design will be of
simpler construction and probably a better solution.
For more information, please consult the article on swivels on the Rocna
Knowledge Base.

That looks like a non cogging self righting swivel, specifically made for the Rocna anchors.

The reason that one is so poplar with Rocna owners is that since the Rocna wont set or hold, when you drag it around the anchorage it won't clog up.

I have found that a chain groove in the bow roller does a much better job of orienting the anchor on retrieval that a swivel, and since you can use regular shackles, it is far less prone to failure. And I'll bet you could get a groove machined in your roller for the same cost or less than you would pay for a swivel.

The grove ensures that the chain pays out and retrieves without twisting. When properly shackled, and your anchor comes up, gravity causes it to always rotate to the right orientation. Ours comes up correctly 100% of the time.

I found a swivel to actually be as much a part of the problem with anchors coming up the wrong way as they were a solution for correcting alignment. Because they swivel, they allow the anchor to lose it's orientation, so it then comes up backwards or sideways. And I when it did come up wrong, I didn't find it any easy feat to get it straightened out. After a few uses the swivel tends to bind up with sand and mud making swiveling difficult. And when you try to rotate the anchor, the chain just wants to twist rather than the swivel swiveling. So I kinda thought they sucked.

Isn't ROCNA just a misspelled and backward spelled ANCHOR?

Manyboats: My Willard 40 carries a 55kg Rocna and I'm frustrated by the way it will often turn "backwards", making it difficult to haul over the bow roller. I found a ready made "righting swivel" called the Twist sold by Italian Osculati Marine but not sold in the US or Canada. I may have to have one made custom. Any leads to a retailer will be appreciated.

Yes, upside down. Just like when your anchor turns turtle.

Never have that problem with my inexpensive-and very-effective Bruce-knockoff Lewmar Claw. Sure glad I didn't waste all that money on an upside-down Sarca or Rocna!!
