To choose the correctly sized Rocna or Vulcan anchor, find your vessel’s length from the column on the left, then track across that row until you find the first column with a displacement (in tons) the same or larger than the displacement of your vessel. The top of the column with the selected displacement indicates the recommended Rocna or Vulcan anchor.Visit http://rocna.cmpgroup.net/ for additional information.
Our anchor sizing is conservativeUnlike other manufacturers, our anchor sizing recommendations are intended to provide an anchor adequate for use in most all conditions. We base our calculations on 50 knots of wind, associated surge, and poor holding bottoms. For more on our philosophy and rationale, please consult our Knowledge Base article on our sizing recommendations. This chart is a guideline only, so if you’d like further information please enquire with us for further advice.
