Rocna anchor Model 20G Original, galvanized, 44 pound. Rocna anchors stand out for their holding power, setting ability and ease of use.? Designed to set quickly in all types of sea-beds, their unique geometry enables them to orient themselves for fast penetration, regardless of how they hit the bottom.? They combine a chisel tip, roll-bar and skids to dig in straight and bury rapidly, typically within one meter, even in thick weed and kelp.? Shanks of quenched and tempered high tensile steel make them extremely resistant to the twisting and bending forces present when the anchor is under load.? The Rocna's folded fluke geometry resists wind and current shifts and doesn't easily trip out upon load reversal.?
