Fortress
Fortress anchors are engineered for performance.
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, which was noted in the test report summary:
“The fact that the Fortress anchors incurred no significant structural damage at such high holding ratios suggests that the anchors have been extensively engineered from both the hydrodynamic and structural standpoints.”
