The Vulcan Rocna Anchor
£225.00 – £7,500.00
Legendary Kiwi design, leading the way in next generation anchoring.
Instant set, self-launching, rock solid holding power and resistant to wind and tide shifts, an innovative roll-palm at the rear of the fluke self-rights the anchor on the seabed.
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, including those with platforms and bow sprits for vessels from small runabouts to large yachts and powerboats.
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 require improved anchoring performance.
The Rocna Vulcan Yacht Anchor is a development of the original Rocna Anchor for customers seeking the exceptional holding power and setting performance of a Rocna Anchor without the difficulties of accommodating a roll-bar design on their bow.
The Vulcan anchor 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 requiring improved anchor security.
The Vulcan features a unique combination of shank and fluke geometry – including an innovative roll-palm™ 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™ 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 is similar in design to the Rocna, directly equating to more holding power and security.
The omission of a roll-bar along with a carefully designed shank profile 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.
The Vulcan’s shank shape 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.
In addition to the use of high tensile steel, shank strength is optimized by a unique I+V profile™ shank design, delivering improved resistance to bending courtesy of a computer optimised I-beam geometry. This visually elegant innovation also improves setting performance, with the lower V edge cutting into the seabed and minimising resistance to a deep and secure burial.
Built from the highest quality materials, a high tensile steel shank and the best quality welds and finish ensure strength and durability. Every Vulcan anchor comes with a lifetime guarantee against both breakage and bending in addition to manufacturing defects.
Vulcan yacht 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.

There’s a Rocna or Vulcan yacht anchor to suit just about any vessel – including larger sizes not featured here. To choose the correctly sized Rocna or Vulcan anchor for your boat, follow the chart and instructions.
To choose the correctly sized Rocna or Vulcan anchor, find your vessel’s length from the column on the left, then track across that row until you find the first column with a displacement (in tonnes or pounds) 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.
Our anchor sizing recommendations are intended to provide an anchor adequate for use in most all conditions. We base our calculations on 50 knots of wind, associated surge, and poor holding bottoms. This chart is a guideline only, so if you’d like further information please contact us for further advice.
NOTE: We do not provide standard recommendations for boats larger than those for which the Rocna 110 (243 lb) would be the recommended size. This is because of increasing complexities of the factors involved. Furthermore, classification society rules and/or legal requirements are likely to dictate the anchor sizes mandated for these vessels. Rocna anchors from size 110 kg (243 lb) and above may be sized based on classification society Rules for Ships for SHHP anchors. Modern rules permit a mass 33% lighter than HHP types, or 50% lighter than “standard stockless” types. Anchor sizing is based on a vessel’s separately calculated Equipment Number (EN). For more information, please contact us.

Which Will Fit Best, Rocna or Vulcan?
The Rocna anchor has set the bar for the highest performance and reliability when put to the test. The Vulcan infuses as many as possible of the proven performance advantages of its elder sibling, while being specifically designed to fit a wider range of vessels. For the Vulcan, the omission of a roll-bar along with a carefully designed shank profile ensures a snug fit on bows. Platforms, bowsprits, prods, stays, and other protrusions are easily cleared.
3D or 2D CAD Files
We are able to supply naval architects or boat builders with accurate CAD files of all Rocna and Vulcan models to support the proper integration of the anchor into a boat’s ground tackle system. Contact us for more information.
