Vulcan Galvanised Anchor 20 kg - 77-106-075
Rocna Engineering - High Holding Power Without the Roll-Bar
The Vulcan anchor is a major design evolution from Rocna, specifically engineered to provide exceptional holding power for vessels that cannot accommodate a traditional roll-bar anchor. Ideal for powerboats with bow pulpits and sailboats with bowsprits, the Vulcan features a unique combination of shank and fluke geometry that ensures a quick, deep set in nearly all seabed conditions, including mud, sand, and kelp.

Questions & Answers
Is this a genuine original part?
Yes, this is an authentic Rocna Vulcan anchor, manufactured by CMP Group to the highest marine standards.
How do I know if it is compatible?
We recommend checking the SKU/MPN (77-106-075 / VLC20GS). This model is specifically designed for vessels between 10m and 14m that have bow platforms or pulpits where a roll-bar may interfere.
Can it be used for tandem anchoring?
Yes, the Vulcan 20kg features a dedicated tandem anchoring attachment point at the rear of the fluke, as well as a separate attachment point for a buoyed retrieval line.
Note: Sizing recommendations are based on 50 knots of wind and associated surge. For multi-hulls, we suggest selecting one size larger than the standard recommendation. Visit 4boats.co.uk for more information.
