ROCNA – ROCK SOLID:
The Rocna anchor was designed by New Zealand sailor Peter Smith, who has been designing, building, and sailing boats since the early 1960’s. Over 100,000 nautical miles of cruising, Peter experienced the same anchoring problems that are still prevalent today – needing to carry a variety of anchors to suit various seabeds, yet still the anchors dragged and boaters felt insecure.
“Your anchor should provide you and your crew with reliability, security, and confidence,” says Peter. A lifetime of nautical experience worldwide was poured into an anchor – initially conceived for Peter’s own use – which became the Rocna.
Peter’s solution consistently returns top results in objective and independent testing. Since its launch in 2004, the Rocna has led worldwide anchor tests as published in the likes of SAIL, Yachting Monthly, Practical Boat Owner, Voile, and others. Because of the Rocna’s reliable and convincing performance against its competition, Rocna is trusted to be rock solid in the real world. You don’t need to take our word for it.
ROCNA – THE ORIGINAL:
FOR ALL WHO NEED RELIABILITY FROM PERFORMANCE
Rocna anchors are performing in some of the world’s toughest locales, including Patagonia, Antarctica, Alaska, Greenland, Scotland – as well as enduring temperamental tropical weather. Rocna has “buy-in” from respected boaters whose opinions matter, from Steve Dashew to Jimmy Cornell. Southern lattitudes sailing pioneer Jérôme Poncet reports: “It took me years with many trials to achieve, in discovering the Rocna anchor, foolproof holding power…”
The roll-bar (A) ensures that the anchor always arrives at the ideal angle for penetration, and the setting skids (B) guide the fluke tip (C) which acts as a sharp chisel cutting into the seabed. With a third of the anchor’s weight on its fluke tip, an instant reliable set is ensured with every use.
ROCK SOLID HOLDING POWER
Of all anchor types, a concave fluke (D) gives the greatest resistance, and through clever design Rocna provides the largest fluke area possible. In very soft seabeds, this provides the holding power to secure your boat. On hard or weedy sea floors, Rocna’s chisel tip (C) ensures that it cuts through and bites deep.
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, and does not roll out on reversal or veering of load, or if dragged beyond yield, providing enhanced security.
HIGHEST QUALITY BUILD AND FINISH
Compare the welds and finish on a genuine Rocna anchor to alternatives. We believe a top performing product should be built like one, and we spend a lot of time and resources on production and quality control procedures to ensure that this is the case.
HIGH TENSILE STEEL SHANK (E)
Rocna anchors are designed – and built – for strength and durability.
SELF-DEPLOYING AND SELF-RECOVERING
The Rocna shank is designed so the anchor self-launches and self-stows on the majority of bow-rollers, with the greatest possible reliability.
GUARANTEED FOR LIFE
Each Rocna anchor comes with a Lifetime Warranty against both breakage and bending in addition to manufacturing defects.
COMPETITIVELY PRICED WITH WIDE PRODUCT RANGE
Rocna anchors are available in 14 sizes from 4 kg (9 lb) – 275 kg (606 lb) to suit all vessels from small boats to small ships. Larger sizes available on request. Galvanized and stainless steel options are available in all sizes.

VULCAN: IN THE FOOTSTEPS OF ROCNA
The new Vulcan anchor is Rocna’s first major design development since the launch of the highly successful and acclaimed Rocna anchor itself. Following on the success of the Rocna, designer Peter Smith was often approached by customers seeking to experience the exceptional holding power and setting performance of a Rocna, but who had difficulties accommodating the roll-bar design on their bow.
After years of testing and development, Peter has come up with a design that meets the needs of these customers – the Vulcan.
The Vulcan is carefully designed to offer the greatest possible compatibility across a wider range of vessel bow configurations, particularly powerboats with a bow pulpit. It brings the security and reliability of the Rocna anchor, highly successful and popular with offshore cruisers and adventurers, to a wider range of boaters who we believe desire improved anchoring performance.
AN INHERITANCE OF GENUINE PERFORMANCE
The original Rocna has ”set the bar” for the highest performance and consistency of behaviour when put to the test both by a worldwide array of users and in numerous independent tests. This performance is the result of careful design and engineering by Peter, who has again put to work all of his knowledge and experience to develop a variation on the theme of the ultimate anchor. The new Vulcan capitalizes on already finely tuned design elements, infusing many of its elder sibling’s proven performance advantages for an extremely quick and reliable set across a range of seabeds combined with rock solid holding power.
NEW SOLUTIONS FOR OLD CHALLENGES
Breaking from the Rocna design, the Vulcan features a unique combination of shank and fluke geometry – including an innovative roll-palm™ (A) at the rear of the fluke – which self-rights the anchor on the seabed without the use of a roll-bar. This is assisted by the V-bulb™ (B) which extends fluke ballast downward to gain maximum leverage and efficiency. This development permits a larger fluke surface area than competing designs which rely on simple dead weight, while the concave fluke (C) is similar in design to the Rocna, directly equating to more holding power and security.
FIT FOR ALL VESSELS – AND THEIR OPERATORS
The omission of a roll-bar along with a carefully designed shank profile (D) ensures a snug fit on the bows of a widely expanded range of vessels. Platforms, bowsprits, prods, stays, and other protrusions are easily cleared with no hassle or inconvenience.
SMOOTH BOW INTERACTION & COMPATIBILITY
The Vulcan’s shank shape (D) encourages self-launching and self-stowing upon retrieval on the majority of bow rollers, with a liquid smooth action, ensuring ease of use for all operators.
STRENGTH FROM SOPHISTICATED DESIGN
In addition to the use of high tensile steel, shank strength is optimized by a unique I+V profile™ shank design (E), granting improved resistance to bending courtesy of a computer optimized I-beam geometry. This visually elegant innovation also improves setting performance, with the lower V edge (F) cutting into the seabed and minimizing resistance to a deep and secure burial.
IN THE IMAGE OF THE GODS
Embodying the rugged strength and elegant designs of its namesake – the ancient god of fire and metal smithery – the Vulcan is milled from the heritage of the Rocna anchor and the demands of innovation. Formed from high strength steels or stainless steels, and finished with the utmost attention to detail and quality.
GUARANTEED FOR LIFE
Like the Rocna, each Vulcan anchor comes with a Lifetime Warranty against both breakage and bending in addition to manufacturing defects.
COMPETITIVELY PRICED WITH WIDE PRODUCT RANGE
Vulcan anchors are available in 10 sizes from 4 kg (9 lb) – 55 kg (121 lb) to suit vessels from small runabouts to larger launches. Galvanized and stainless steel options are available in all sizes.

THE ROCNA FISHERMAN
The Rock Solid Fish & Dive Anchor. The Rocna Fisherman is a variation of the Rocna Original, and enjoys identical performance to bring you all the same security and reliability as its elder sibling. Designed as a specialist anchor for fishermen and divers who run an increased risk of getting their anchor stuck on an undersea obstacle, the Rocna Fisherman features a shackle rail™ for easier recovery of a fouled anchor.
CHOOSE THE ROCNA FISHERMAN:
For smaller boats that re-anchor frequently. For easier anchor retrieval in difficult conditions. For day trips rather than extended cruising.
Finish: Galvanized; Sizes: 4 kg (9 lb) & 6 kg (13 lb) only
CONVENIENCE OF RECOVERY
A float shackled to the dedicated retrieval line attachment point at the heel of all Rocna anchor flukes is the ideal recovery system, offering the best chance of a successful recovery in the event of a fouled anchor. However, the shackle rail™ system of the Rocna Fisherman offers convenience with automated recovery. This variant of the Rocna may be used in either of two distinct modes, as the shackle rail™ is complemented by a secure point which allows normal safe anchoring when the recovery functionality is not required.
If you believe the anchor is at risk of becoming stuck on the seabed, the rode is attached to the shackle rail™ slot. This mode should not be used overnight or if the boat is to be left unattended. To retrieve if and when fouled, the vessel is moved over the anchor with reduced scope, and the anchor is pulled backward. The shackle slides to the other end of the slot, an improved point from which to pull the anchor clear. The secure point is shackled to for overnight anchoring, or when the vessel is left unattended. This prevents an unintentional un-setting of the anchor in the event of a wind or tide reversal.
ROCNA FOR WORKBOATS
ROCK SOLID PERFORMANCE
Rocna consistently out-performs the competition in independent testing. For example, in the SAIL magazine test of 14 anchors, Rocna was #1 in holding power… 40% more than the next best competitor. That translates to efficiency: more performance, more security, more reliability – for less weight and less financial investment.
SHHP CLASSIFICATION & CERTIFICATION
The Rocna is an SHHP (Super High Holding Power) anchor, with classification at this time applying to sizes 55 kg (121 lb) to 110 kg (243 lb) and enquiries welcome for larger sizes. Society Rules permit an anchor size 33% less than HHP (Lloyd’s, RINA, and most other Societies) or SHP (ABS) types, and 50% less than “standard stockless” types.
RUGGED STRENGTH FOR THE TOUGHEST BUSINESS
Heavy-duty construction is attained through clever design and the use of high-quality steel. A high-quality hot-dip galvanized finish covers the entire surface with protective zinc, including the interior of the hollow roll-bar. A Rocna is strong, durable, and can be Relied on to look after your vessel for the long run. Rocna – rock solid.
