Rocna Original Plough Anchor- Rock Solid Design, Rocna’s legendary Kiwi design.
Choose the Rocna Original Anchor:
-For the best multi-purpose anchor that sets in all ocean floors.
-For vessels of all sizes, from small runabouts to superyachts.
-For an SHHP (Super High Holding Power) type anchor (for details of RINA classification, click here).
Sizes Available: 4kg - 275kg (9lb - 606lb)
-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.

Rocna Original Plough Anchor Sizing Guide: (1 Tonne=1000kg)
*Please refer to the image to help in your selection also.
To choose the correctly sized Rocna, match your vessel’s length with the most appropriate displacement range, also bearing in mind conditions of intended use (if in doubt, give preference to the larger anchor model).
For multi-hulls: use the chart as instructed, then select the model one size larger.
Tips from Rocna:
Chain: As a minimum, we recommend using medium tensile / G40 / High Test chain with your Rocna anchor. (If it is available, practical and affordable, high tensile / G70 chain is preferable as it is a lighter weight to carry). For more information, see the Smart Crew.
Rocna's sizing philosophy: Sizing recommendations are intended to provide an anchor adequate for use in most all conditions.
Sizing larger anchors: For Rocna anchors 150kg and larger, the sizing calculation becomes somewhat more complicated and it is suggested that anchor selection be based on RINA Rules, Part B, Chapter 10, Section 4, as appropriate for SHHP (Super High Holding Power) anchors. After calculating a vessel's EN (Equipment Number) per the RINA Rules, the appropriate anchor can be selected as follows:
- Rocna 150 (150kg, 330lbs) - Appropriate for EN 90 - 110
- Rocna 150 (150kg, 330lbs) - Appropriate for EN 90 - 111
- Rocna 150 (150kg, 330lbs) - Appropriate for EN 90 - 112
Rocna strongly encourage that you seek further assistance from a professional familiar with ground tackle selection for larger vessels and the application of the RINA rules. See the Smart Marine Crew for assistance in your selection.
