'Rocna anchors are raising the bar of boat-owners' expectations on anchor performance'
Recent independent tests by publications such as Cruising World, Practical Sailor, and SAIL show that new-generation type anchors consistently outperform more traditional designs.
Through careful design, the Rocna does not waste energy with extra lead or cast iron weights, meaning weight is more efficiently used in structural strength and extra blade area (holding power). On a comparable weight for weight basis, this means greater security for cruisers, or a lighter anchor for weight sensitive craft.
The ground tackle including the anchor are one one of the main priorities on any yacht.
A Rocna means more enjoyable and safer boating, a less anxious crew, and a good night's sleep.
'Your Rocna is the bottom line.'
Self Launch Shank
The roll-bar ensures that your Rocna turns to the optimum angle for pulling in to the seabed.
The sharpness and the weight (a third of the anchor weight) of the chisel fluke tip, guided by the Setting Skids, facilitates penetration.
A Rocna will reliably set itself every time
ROCK SOLID HOLDING POWER
The Rocna Anchor has a concave fluke which gives the greatest possible resistance.
The Rocna design delivers maximum fluke area for maximum holding power.
The accent on concave fluke area provides the holding power in very soft seabeds.
The Rocna chisel tip ensures that it cuts through hard or weedy sea floors and bites deep for a safe set.
The Rocna is a true multi-purpose anchor that sets and holds in most seabeds, from soft mud to hard sand, clay, grass, and kelp.
RESISTANT TO WIND AND TIDE SHIFTS
A Rocna remains stable and buried i.e. it doesn't roll out when the load veers or reverses or if it is dragged beyond yield.
HIGHEST QUALITY BUILD AND FINISH
The welds and overall finish compare very favourably with any competitor.
Rocna believe a top performing product should be built like one.
Rocna spend a lot of time and resources on production and quality control procedures to ensure that this is the case.
HIGH TENSILE STEEL SHANK
Rocna anchors are designed and built for strength and durability.
SELF-DEPLOYING AND SELF-RECOVERING
The Rocna shank is designed so that the anchor self-launches and self-stows on the majority of stemhead bow rollers with the greatest possible reliability.
GUARANTEED FOR LIFE
Every Rocna anchor comes with a Lifetime Warranty against breakage, bending and manufacturing defects.
Sizing Chart: In photos
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 anchor sizing is conservative
Unlike other manufacturers, Rocna anchor sizing recommendations are intended to provide an anchor adequate for use in the most severe conditions.
Rocna base their calculations on 50 knots of wind, associated surge, and poor holding bottoms
