Re: How good is the Rocna?
Genuine will have the raised letters C,Q,R in the shank beam.
They are a hella tough forged hunk of metal. Very expensive when new.

For about $40US you can get a big fat bolt installed.

I'll have a look next time I'm down on the boat. It will be nice to have finally got a winner.

I think this is a critical point. The best anchor in the world is still only a small hunk of metal until it is set properly. Most anchoring problems I have seen are more related to poor technique than bad anchor choice. A properly set "old style" anchor is going to be better than a poorly set new-gen anchor.
Of course, the new gen anchors tend to set easier than the older styles. And they reset better as well. But technique, including proper rode, matters big time. So don't just invest in an expensive new anchor. Invest in the skills necessary to make them work.

Re: How good is the Rocna?
My experience with Rocna was not what some appear to have achieved. I have a 15kg RRR rocna purchased through Rocna from the Sydney boat show some years ago and whilst it is streets ahead of the delta that was on board when i bought the boat it still dragged more times than I was prepared to accept.
It may be that the anchor was marginal in size for my boat (the rocna sales rep insisted that it was the correct size for my boat, and that he knew the brand of boat we were discussing) or that the mud that I sometimes anchor in simply clogged the anchor but it didn't work as I wished and I have since found an anchor better suited to my boat.
If anyone in Sydney Australia is interested in buying an original pre-china NZ made 15 kg RRR don't hesitate to message me.

What's the weight of your boat uncle?
According to their web page 'now' mine is very much over powered. But when I purchased it, my 25kg for a 36 footer up to 10tonne is what they recommended.

Re: How good is the Rocna?
Rocna sizing shows for the 15kg, 10 meters and up to 8.5 tons.
Looks like uncle bob's boat is 9.75 meters and 8.4 tons. So just in the recommended.
Don't mean to speak for ub, but just wanted to throw this post in to wonder out loud about a couple of things.
Like should added windage from the pilot house be considered.
Or what about the load carried by a boat. Mine in 6.25 tons but I'd guess an added ton of load. I'm a couple inches lower in the water now six years in.

Re: How good is the Rocna?
We have a 33kg Rocna Very impressed with the holding power but very disappointed with the quality control. We have 2 rust spots on it already and its not even 6 months old ! I intend to get some photo's and send them to Rocna. Must have been made on Chinese new year !!

Were there spots that weren't galvanized when you purchased it, or did the zinc get scratched from use?

Re: How good is the Rocna?
Looked good when I got it ! Only been anchored in sand or mud with it so far ! Both rust spots are in the same place at the ends of the roll bar .

Amen to that!
And it's amazing how many cruisers don't even test how well they've set their anchors.
It's very simple -- if the anchor is set, you can't pull it out with engine power. So once you've finished setting it, or think you have, just run the engine up to full power and let it run for several minutes. Watch the chart plotter zoomed in to see if you've budged, and/or watch a good transit. If you don't budge an inch, the anchor is set. Make the sundowners. If you are able to move the anchor with engine power, it's not set, and you need to pull it up and do it again, or look for a better spot. It's that simple.

Four winds, your figures are pretty much on the money, and as said the rep assured me that the sizing was correct.
To be fair the anchor is so much better than the sometimes set delta, but still not quite what I was hoping for.
I have found that the excell from Rex to be a much better fit for me.

Good feedback from a user of a Rocna and a Sarca Excel.
The Excel certainly gets a great rap from users.

Iirc the ends of the tube are cut straight leaving a fairly sharp edge which would cause any coating (paint or galvanizing) to be thinner and wear or erode faster. Perhaps Rocna will fix it, but if not you can try Ospho and cold galvanizing spray.
