For multi-hulls: use the chart as instructed, then select the anchor model one size larger
Our sizing is conservative
Our sizing recommendations are intended to provide an anchor adequate for use in most all conditions. We base our calculations on 50 knots wind, associated surge, and poor holding bottoms. For more on our philosophy and rationale, please consult our knowledge base article:
If your vessel is outside these specs then ref to Rocna range and sizing chart for correct anchor size.
