The New Zealand Marauder Association has an affinity for Rocna anchors, with some of the feedback reproduced below from their newsletter. A Rocna 10 was donated as a prize for their 2006 National Championships, and the following entry is by the winner.
Report on Rocna anchor
Peter Knight, Real MacCoy
This year our Marauder Real MacCoy won the 2006 New Zealand Marauder Class National Championship and took out the Barry Olliff Trophy. Our prize for topping the National regatta was a Rocna 10 anchor.
I had seen these anchors advertised, and had thought about getting one as we do a lot of racing – I had become aware of the fact that the Rocna 10 was a bit lighter than the heavy 25 lb plough that I had been using.
Imagine my surprise to find that the prize we had won was the Rocna anchor. It couldn't have come at a better time. It is now on the boat all the time and I am extremely happy with it!
When I got it, my first thought was that it would never fit in the anchor locker, but it does – I just grab it by the roll-bar and put it in shank first, it is much easier than trying to fold up the old plough.
Our normal set-up is to have the length of the boat in chain, and the first time we used the Rocna 10, we put it down and did the usual reverse bit. It took up so quickly I just about went over the bow of the boat – the old plough used to take a while to dig in but the Rocna was instant. (Maybe we could have a warning here: "When backing up please sit down" – just kidding).
We have not experienced the holding in a big blow to date, but I have huge confidence in this anchor because of its ability to really dig in. Holding power is exactly what we are all looking for in an anchor.
If anyone is considering a new anchor, I would be very happy to recommend a Rocna. You would have to look long and hard to find a better anchor.
The following is a full review of a Rocna 10 on a Marauder cruising around Auckland, New Zealand.
An Anchoring Tale
Maurauder Mainsheet July 2006
Tom Niblock & Pauline McAuley, Shanaro
At the end of summer I had the opportunity to trial a Rocna 10 anchor courtesy of the manufacturers.
After cutting the corroded shackle joining my plough anchor and the chain, and thinking that someday Auckland City will lose its electricity with shackles that looked like this, I fitted the Rocna and then looked at the anchor-well, the Rocna, the anchor-well, and panicked for several minutes thinking how the blazes does this go in there. If you don’t know these new types of anchors, I should explain they are built as a pointed wedge blade with a roll-bar in the middle and a rigid shank or shaft at the other. Well to my surprise, by reversing the storage process, i.e. shaft first, the anchor actually stowed easier than the plough. You can get a solid grasp on the roll bar and maneuver the anchor easily.
I of course like every first time user, read the anchoring instructions on the manufacturers' website, www.demo.rocna.co.nz, and noted that they recommend to slowly reverse to bed the anchor and that the anchor grips faster than other types. Yeah right! First anchorage was Izzy Bay, Rangitoto Island – Pauline did her usual reverse circle at modest speed and I nearly shot over the pulpit as the anchor set so quickly in the mud. Wow! I'm sure my arms are a little longer. Over the course of that weekend we anchored in several bays with the same first-drop setting, in the end virtually nil reverse – just let the wind blow you back. And there were several bonuses: firstly, between anchorages the Rocna sat perfectly over the bow due to its rigid shaft, and secondly, the Rocna 10 is both lighter and with the roll-bar is a breeze to handle compared to my 25 pound plough.
The following weekend was a blustery Northeasterly and the anchorage at Ponui Island was fairly gusty, with the anchor line groaning over the fairlead. Despite having this new anchor out I can’t be sure I even checked our position during the night. In the morning I couldn't break the anchor free until we motored over the top. There is provision for a retrieval line attachment. Later that day we fished at several spots including the sandy channel between Ponui and Sandspit Island. Our last stop was at Sunday Rock in the main passage. Our depth sounder was showing an extremely rocky bottom and with opposing wind and tide the chop was about half a metre and current flow was about 2 knots. No drama, we just dropped the Rocna and the fishing lines, drifted back a little and we just sat there without the usual nervous checking of marks to see if we were holding. Bliss.
It was with great reluctance that I returned the anchor and if anyone is in the market to purchase a new anchor I can only say forget the plough types and go for a Rocna.
