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. 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. Rocna anchors are designed – and built – for strength and durability. The Rocna shank is designed so the anchor self-launches and self-stows on the majority of bow-rollers, with the greatest possible reliability. Each Rocna anchor comes with a Lifetime Warranty against both breakage and bending in addition to manufacturing defects. 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.
