Fortress
: Since 1986, Fortress anchors have proven to be the best boat anchors in the world. These high performance anchors are precision-machined from a high-tensile, corrosion-resistant, aluminum magnesium alloy, and are sharper and able to penetrate faster and deeper into most common sea bottoms than heavier, dull-edged traditional steel anchors which weigh 50% more or even greater.
In the US Navy tests, not only did the Fortress anchors out-perform much heavier steel anchors, they were also able to withstand pull loads that averaged over 200x their own weight ... and without incurring serious damage to the anchors.
