The Vulcan 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.

Vulcan: An inheritance of genuine performance

The Vulcan capitalizes on finely tuned design elements from the Rocna pattern, infusing proven Rocna performance advantages for an extremely quick and reliable set across a range of seabeds combined with the expected Rocna holding power.

NEW SOLUTIONS FOR OLD CHALLENGES: Breaking from the Rocna design, the Vulcan features a unique and patented shank and fluke geometry – including the 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.

FIT FOR ALL VESSELS – AND THEIR OPERATORS: No roll-bar and 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 cleared with less inconvenience.

SMOOTH BOW INTERACTION & COMPATIBILITY:The Vulcan’s shank shape (E) 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: Working with high tensile steel, the Vulcan shank (E) is further strengthened by our patented I+V profile™ design. This computer 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.

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 shares the heritage of the Rocna anchor and is born of innovation.

TANDEM ANCHORING ATTACHMENT POINT: For extreme adventurers to extend their horizons even further.

SOLID STEEL: One-piece design for crew safety, ease of use, and simplicity of maintenance.

FINISH OPTIONS: Hot-dip galvanized coating for economical durability, or mirror-polished stainless steel for ultimate aesthetics and extended service life.

“I have now used the Vulcan several times and I’m impressed by the way its shape enables it to drop so beautifully without any initial pushing of it over the bow roller. It also stows away with ease on retrieval – so far it has come up cleanly over the bow roller without any need for me to help it by twisting the chain.

The holding seems to be at least as good as my trusty Rocna showed itself to be over several years. All in all, I’m very happy with the Vulcan, just as I have been with the Rocna.”
