MK II Stainless Steel Fixed Shank Scoop Anchors

The new Rocna® Mk II anchor is the first major improvement since the launch of the acclaimed Rocna Original. After years of careful testing and refinement, and exploiting innovations also found in the well-received Vulcan® anchor, New Zealand designer Peter Smith has honed the ultimate anchor: the Mk II.

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, all retained and tuned in the new Rocna Mk II. Substantial upgrades in performance and strength are achieved through revision and refinement – inheriting and uprating the original’s proven performance advantages for an extremely quick and reliable set across a range of seabeds, with rock solid holding power. Unique patented roll-foil™:

The Rocna roll-bar has been sculpted into the patented roll-foil™ providing even surer self-righting for the most reliable 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.

Stronger Patented I+V profile™ shank:
Working with high tensile steel, the Rocna Mk II shank has its strength maximized by the patented I+V profile™ design, and is the toughest Rocna shank of all. This optimized I-beam geometry brings higher resistance to bending, and 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 and weight distribution upgrade for ultimate holding power:
The fluke has been optimized for weight distribution, penetration, and strength. It boasts a new weighted and reinforced tip. The tried-and-true Rocna fluke is increased in surface area, for a substantial boost in holding power without trade-off.

Features:

• Based on the proven Rocna design pattern, with improved performance and strength
• Precision setting: the roll-foil™ ensures the anchor always arrives at the ideal angle for penetration, and the skids guide the fluke tip which chisels into the seabed for an instant reliable set
• Concave fluke (redesigned and optimized) for 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
• Resistant to wind and tide shifts: All Rocna anchors remain stable and buried, and fight roll-out on veering of pull, or if dragged beyond holding ability, providing enhanced security whatever the circumstance
• Multi-purpose anchors that set and hold in most seabeds, from soft mud to hard sand, clay, grass, and kelp
• Self-launches and self-stows reliably on the majority of bow-rollers
• I+V™ profile high tensile steel shank for improved strength and setting performance
• Mirror-polished solid stainless steel one-piece design for ultimate aesthetics and simplicity of maintenance.
