The idea is to envelope, hi winds and poor bottom (loose silty low viscosity bottom), we size the gear so to insure safety with a cruising anchor in 40 knots and poor bottom... We believe our to be the single best all purpose anchor on the market (you will have a guarantied set). In areas with silty bottoms you need a bigger blade surface area to achieve the same needed holding power, so we develop the sizing guide to envelope the worst possible situation as described.
