For over three decades, the much lighter Fortress Anchor has out-performed substantially heavier steel anchors in holding power tests conducted all around the world. In the US Navy tests, not only did the Fortress out-perform heavier steel anchors, they were also able to withstand pull loads that averaged over 200x their own weight. Fortress Anchors are constructed using a high-tensile, corrosion-resistant, aluminum magnesium alloy. This results in a lighter, easy to handle anchor with superior holding power.
The anchors have been designed to be easily disassembled for compact storage, or as a spare and/or a storm anchor. All Fortress Anchors are precision-machined for sharpness and quick penetration into common sea bottoms, which ensures faster setting-performance.
