How much better is a Rocna?
To answer that question, here are some hard figures. This data is independent; it is from West Marine’s 2006 anchor testing, which involved no less than fourteen types, three locations, and three different scopes (3:1, 5:1, and 7:1). The testing was written up in SAIL magazine (USA) and Yachting Monthly (UK) and the graph below is from SAIL:
“Max before releasing” is the force the anchor withstood before moving (i.e. the effective holding power) and is the critical indicator of performance. The lack of the “Max pull” measurement for any given anchor is bad, as it implies the anchor pulled free rather than remaining embedded.
Demonstration Sets and video
It is difficult to photograph most tests, since under increasing load the Rocna commonly buries itself totally, disappearing from sight. You can see this in our video. The photo on the right shows one such buried demonstration model (we have actually cleared most of the covering sand away by hand) – this Rocna 20 got this far before the 20mm rope we were using snapped under the load.
Our short video is the best way to see for yourself the setting performance of the Rocna, as well as experience how it compares to other anchors. Click on the video below to watch.
This Rocna has set itself perfectly in less than a meter.
