Rocna Next Generation Anchors


Rocna sets the benchmark for anchors.

From the North West Passage to the Antarctic, Rocna is the first choice of offshore cruisers. A Rocna anchor's advantage is in its design and construction. With a design philosophy of maximum durability, reliability and ultimate performance. Rocna makes no compromises in any area.

The Rocna is an SHHP (Super High Holding Power) type anchor. During seabed testing for classification, Rocna anchors exhibited the highest holding power of any anchor that classification society RINA had ever certified. And when tested to destruction, Rocna anchors exhibit strengths in excess of six times the SHHP proof load requirements.

The quality of each Rocna anchor is assured due to the proven and effective Canada Metal quality management system and backed by a life-time warranty against manufacturing defects.*

The accuracy and consistency of CMP's manufacturing process results from their dedication to document control, detailed inspection, strict audit policy and continuous training. CMP have exacting material and quality standards to ensure the completed product exceeds customer expectations.

Rocna rolls upright and sets from any angle.

Penetrates immediately even in thick weed.



Independantly testing has proven that Rocna has far superior holding power to traditional anchor types.


Rocna’s legendary Kiwi design, leading the way in next generation anchoring.

Choose the Rocna Original:

For the best multi-purpose anchor that sets in all ocean floors.

For vessels of all sizes, from small runabouts to superyachts.

Finish: Stainless Steel or Galvanized

Sizes: 9lb – 606lb (4kg – 275kg)

Features of the Rocna Original:

  • Instant set: The roll-bar ensures that it always lands on the ideal angle for penetration, plus reinforces the blade for massive strength.
  • The setting skids elevate the heel and correctly direct the tip, for reliable setting in soft seabeds.
  • Self-launching: The shank is high tensile steel, and designed so the anchor self-launches.
  • Rock solid holding power: Of all anchor types, a concave blade gives the greatest resistance, and through clever design Rocna provides the largest blade area possible. The result – massive holding power.
  • Resistant to wind and tide shifts: The sharp chisel tip combines with a very high weight on tip (average of 33%), which ensures an instant reliable set with every use. No lead in the tip and no dragging is also environmentally friendly.

Dedicated attachment points for:

  1. Buoyed retrieval line
  2. Tandem anchor
  3. Securing to the bow

- World Famous Sailor Jimmy Cornell.  Lancaster Sound, in Arctic Canada, in the Northwest Passage.

"Last Thursday and Friday we had a 27 hour storm, with gusts of up to 58 knots. We were anchored in Dundas Harbour, on the south side of Devon Island in Lancaster Sound. There were five other yachts there, all waiting for the ice situation to improve to tackle the central part of the Northwest Passage.

Out of the six boats, three didn't drag, and two of those both have 33 kg Rocna Anchors: my own Aventura, and Silver, an Oyster 47 owned by John Andrews (UK).

I can assure you that it was one of the worst experiences in my long sailing life, made worse by the danger of being rammed by other boats dragging their anchors."

Steve Dashew - Yacht Designer & famous sailor

"Wind Horse has 15,000 miles under her keel since launching last year. We've just completed a trip to South-East Alaska, including the outside of Baronof, and Prince of Wales islands, about as wild a country as you can imagine.

Having now used the ROCNA anchor in a variety of bottoms I wanted to tell you how pleased we are with its performance. It does well in poor holding bottoms, even when the ROCNA is set with as little as two to one scope – which is often required by lack of swinging room."

"We are very pleased with our ROCNA anchor and would recommend its consideration to anyone looking to upgrade their anchoring system.

Regards, Steve Dashew"


I have just returned from the MV Kialoa having delivered her from Fiji to New Caledonia via Vanuatu.

With regard to the Rocna anchor supplied to the vessel earlier this year and its performance, I can only offer praise.

Over the 26 years I have been full-time boating, no other anchor I have used has come close to the holding power or quick setting that the Rocna appeared to have.

This is not a statement based on scientific testing but solely on its performance in a real life situation.

MV Kialoa weighs in around 25 tons, and being high wooded with a shallow draft, has a tendency to wander at anchor. I have on a number of occasions, over the 4 years I have managed this vessel, dragged the 40 kg Manson plough that we had fitted. Since fitting the Rocna just prior to steaming for Fiji in June, the vessel has logged approx 6000nm and has spent most nights at anchor. To date we can only praise the holding power of this anchor and would certainly recommend it to others.

To choose the correctly sized Rocna or Vulcan anchor, find your vessel’s length from column on the left, then track across that row until you find the first column with a displacement (in tonnes) the same or larger than the displacement of your vessel. The top of the column with the selected displacement indicates the recommended Rocna or Vulcan anchor.
For multi-hulls: use the chart as instructed, then select the model one size larger.
Rocna's sizing is conservative
their sizing recommendations are intended to provide an anchor adequate for use in most all conditions.Calculations on 50 knots of wind, associated surge, and poor holding bottoms.
