Upside down Rocna - Solution?

[Prairie Chicken]

My apologies if this has already been discussed somewhere in the 52 pages of anchor threads, but Search isn't helping & I'm on a slow connection.

Our new to us boat came with a 22 kg Rocna & it is showing a distinct tendency to come up to the roller upside down. Trying to straighten it to sit properly on the roller requires some serious stretching & boat-hook maneuvering and is bad news looking to happen. This was never an issue with our trusty CQR.

Why are anchor shanks not round? Is this a Rocna issue? Is there a simple solution? Can anyone comment on the "Junction chain-anchor elbow" which suggests it is a solution to the problem?

We have a 25kg Rocna and used it for three years of cruising... You can't find a better anchor!

As for it coming up backwards... When Mine does that I back it down a little and let the chain twist it around until it turns. If for some reason it doesn't I lower so more. It always eventually turns around.

On the other hand, it is definitely heavier on the on the plow side, maybe your roller is angled slightly causing it to turn?

Anchors without weighted tips tend to come up randomly. Since the Rocna's rollbar puts weight in the back, it may even favor coming up backwards. Ours has a swivel connecting it to the chain and it is about 50/50 for us. Since ours comes up right at the bow roller at our feet, we simply turn it by hand.

I don't know what you are referring to when you wrote "Junction chain-anchor elbow", but I would be very cautious on adding any connection except a known good shackle. There are only two swivels I would ever use, and only one I would connect directly to the anchor.

If it's upside down just turn the chain a bit. I have to do that all the time with my Manson Supreme. Nothing to it, just grab the chain and twist a bit. The anchor will turn, then haul it in quickly. I always haul the anchor through the roller by hand. Too easy to wreck things if you use the windlass and it gets stuck coming through the roller. I don't believe in swivels.

Something happened to Rocnas about 18-24 months ago. We suddenly had many saying they were coming up backwards, which was something that we'd only heard occasionally as we do with most designs. No idea why the change but it was quite noticeable with the sudden change.

Fit a 'anchor straightener' and all will be good. Google will find one local to you.

[Jim Cate]

For the OP: Are you moving through the water when the anchor comes to the surface? I have noted that with our Manson Supreme, hydrodynamic forces when going forward will bring the anchor up "backwards", and conversely, if going in reverse, the anchor is in the "forwards" attitude.

Don't know if it is the same with the Rocna, but they are pretty similar anchors, so you might try going slowly in reverse whilst getting the last few feet of chain.

Hi, Prairie

Have a look at this:

60% of the time mine comes right side up
20% of the time it is backwards or sideways when it starts to come over the roller and just waiting for the boat to roll / have movement from a swell will straighten it out.
20% of the time just stand on it / twist chain / push it by hand.

I think I agree with Jim's observation that it's more likely to come up backwards if the boat is moving forward.

Perhaps this is simpler than you realize. Turn the anchor 180 degrees on the chain.

The chain cannot rotate in the gypsy. Ergo, if it is rotated 180 degrees, perhaps you attached it 180 degrees different from the last anchor.

Which explains why 50% of the folks have this mysterious problem.

My experience is like SV Lift. A few moments of random motion do the trick.

But after anchoring for six months the chain is all twisted.

...And that's why, once a year, we remove the anchor, lower all the chain to the dock, and un-twist it, reload it, reapply the anchor. Just one of those things one has to do.

Must be expensive-you have to make an appointment to find how much it is. Might make one on my lathe.

I have a Rocna as well and sometimes it comes up the wrong way buts it just a twist of the chain and we are good to go. But on the cat the anchor is much easier to get at.
What about putting a loop of rope tied at the roll bar that you could reach easily with the boat hook and guide it to the correct orientation ???
just a thought

Yes, we do it every fall when we get the boat out of storage.

Perhaps theoretically, but in practice, there is that bit of chain between the gypsy and the anchor that can have a random twist in it. In our case, that is 8' of chain.

I think most people have said that the anchor comes up 50/50 right way, not that 50% of people don't have the problem and 50% do.
