How good is the Rocna?

[redsky49]

As to the question about Rocnas rusting, here is my experience. Slight rust at the end of one side of the roll bar. This started, I believe, at the sharp edge on the end of the roll bar (pipe). This is in a 4-5 year old anchor, with many nights (five hundred?, six hundred?) spent on the hook. All in salt water.

Similar light corrosion on the chain, due, I think, to the abrasive quality of the bottom composition where I was anchoring. I don't think this would have occurred in the soft mud/goo of the Chesapeake. I have addressed the slight surface corrosion on the chain, and will also use a cold-galvanizing spray on the anchor.

In the past, I annually used a zinc spray on both my CQR and Danforth anchors. I think this aids in extending the useable life of any anchor, and costs only a few dollars - cheap compared to re-galvanizing. Plus, they look better

And yes, the Rocna will frequently come up facing the wrong direction, especially if having any way on. I lean forward, twist the chain a half turn, and up she comes.

The Rocna website has tons of photos. Including mine.

If I could bear the price, the Ultra swivel is designed to right the anchor.

There is also an Osculati swivel which does that, and apparently does it very well.

Not needed with Spade or Ultra anchors, which have lead ballast.

As I said before, I gave away my CQR along with 50 feet of rusty chain and 300 feet of rockhard triple strand. The marine consignment stores have piles of CQRs, standard Danforth's, and surprisingly Fortresses.
A pivoting bow roller make your current system easier particularly if you don't have a winch.

Does anyone have any problem with their Rocna not coming up facing the correct way? I find I've got to use a stick to reach over and turn mine to face the right way before finalisting the pull Really annoying.

By any chance do you use a chain swivel? I know that our anchor would come up backwards because we were moving forward and the anchor would be trying to surf when it gets to the surface. After i installed our swivel once the shank starts over the roller the anchor is able to rotate to the proper position.

Just retrieved from wrong thread...

Pic as promised....

My only issue which i don't think is unique to this anchor is that I have to put my foot on the chain as the shank is going over the roller to stop the chain jumping off the vertical axis gypsy/wildcat and to stop the shank smacking the roller furler drum.

( the black thing growing out of the anchor is the next boat's power cable).

I had a swivel for a couple years. I removed it b/c it really didn't seem to help with the rode twist and anchor retrieval. Still ran into the same issues. Maybe not the right swivel

If it's just a swivel, as opposed to a self-levering device like the Osculati Twist, the swivel alone won't solve the problem -- you still need to turn the anchor with a boathook. The swivel just allows you to do that without the chain twisting and spinning the anchor back around.

OSCULATI Twist connection, anchor-swivelling version

Ooh that looks neat. I wonder how much and where do I get one?

The Ultra Swivel for anyone interested: Ultra Anchors

Yes. I do. And the Swivel, which was damn expensive and needed to be locktighted) doesn't stop the anchor from coming up the wrong way. It does make it easier to turn the anchor with my long boat hook though.

This is pretty much what I have. Not sure of the brand, but it was about $140 - $180.

Be very careful when using this style of swivel and the extension arm that was mentioned ( Osculati ) they can be side loaded! That is the main failure with swivels. Also the area where it turns in most cases can not be inspected.

Best to put 3 or 4 links of chain between swivel and anchor and that will deal with side loads

Now you tell me about these .

Yes, I bet these would force the anchor into the right position. Also bet they're selling for a fair chunk of boat bucks. Looking at it, I'd worry about the force vectors.

It's really not a big deal managing the orientation of the Rocna. I guess I'm all Zen with it.

Actually the Osculate is pretty well designed to prevent side loads. It does not clamp to the shank like many swivels, but rather is designed to connect with a D shackle or two in a way which allows +180 degree movement without side loading. It is a quite cleverly designed device, to do what it does well but very simply.
