Spade Anchor Sizing Guide

The following chart can be used to find the right size of Spade anchor for your application. Unlike other manufacturers, Spade's sizing chart is accurate and includes a margin of safety. These sizings are accurate for use as a "storm anchor" on a typical monohull.

When sizing an anchor choose the model that corresponds the largest required for either the length or weight. For multihulls, choose 1 size larger than recommended in the table (think windage).
