55 lb Rocna MK II Stainless Steel Anchor

Rocna Mk II: Perfecting the Ideal - The Inheritance of Excellence

An idealized form of the Rocna design, the Rocna Mk Il is based on the same proven design pattern, but refines every element close to perfection.

The Rocna has established the highest performance and consistency of behavior when put to the test both by a worldwide array of boaters and in numerous independent tests. This performance is the result of careful design and engineering by Peter, and it is all completely retained and tuned in the new Rocna Mk II.

Peter has again put to work all of his knowledge and experience to develop an improved design that pushes the limits once more. The Rocna Mk II brings substantial upgrades in performance and strength by way of revision and refinement — inheriting and prating the original’s proven performance advantages for an extremely quick and reliable set across a range of seabeds, with rock solid holding power.

PRECISION SETTING: the roll-foil™ ensures the anchor always arrives at the ideal angle for penetration, and helps the skids guide the fluke tip which chisels into the seabed for an instant reliable burial.

ROCK SOLID HOLDING POWER: A concave fluke gives the greatest resistance. In soft seabeds, this provides the secure holding power you need. On hard or weedy sea floors, the weighted chisel tip cuts through and bites deep.

ROLL-FOIL™: Sculpted from the Rocna roll-bar, the patented roll-foil™ providing even surer self-righting for the most dependable set. The roll-foil’s sections vary in profile, each designed for its own dynamic role: to provide extra assistance if the anchor lands upside-down, to help during setting for deeper penetration and greater holding once buried, and to improve soil flow for reduced clogging.

I+V PROFILE™ SHANK: Working with high tensile steel, the Rocna Mk II shank is further strengthened by our patented I+V profile™ design. This computer optimized I-beam geometry brings higher resistance to bending, and the Mk II has the toughest Rocna shank of all. The I+V profile also further improves setting performance as the lower V-edge cuts into the seabed. This helps the anchor penetrate more easily to a deep and secure burial.

FLUKE: The Rocna fluke has been redesigned and optimized for weight distribution, penetration, and strength. It enjoys a new weighted and reinforced tip. Steel moved from where it is extraneous, to where it aids. The tried-and-true Rocna fluke is increased in surface area, for a substantial boost in holding power. And all attained with no trade-offs.

Are Rocna anchors any good?

Due to the Rocna anchor's consistent and impressive performance compared to its competitors, it has gained a reputation for being highly dependable in practical situations. In general, people have been consistently impressed with its reliability and effectiveness.

What is the difference between Delta and Rocna anchors?

The Delta fluke shape resembles a plow with a convex fluke similar to the articulated CQR. It is not very effective in soft mud and unsuitable for weeds or grass (these are specific areas where Rocna outperforms it significantly). In contrast, the Rocna features a large fluke surface area and a concave fluke design that is specifically engineered to provide better ground-holding capabilities.
