No Other Anchor Compares to Fortress Anchors, the Best Value in Anchoring Safety and Convenience


Fortress® anchors are constructed from a high-tensile, corrosion-resistant, aluminum magnesium alloy that is precision- machined into interlocking components with no welds to weaken the metal. This results in a lighter, easy to handle anchor with superior holding power.


Since 1986, the much lighter Fortress aluminum anchors have consistently out-performed much heavier steel anchors in holding power tests conducted around the world. In the US Navy tests, not only did the Fortress® anchors out-perform heavier steel anchors, they were also able to withstand pull loads that averaged over 200x their own weight ... and without incurring serious damage, which was noted in the test report summary:

“The fact that 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.”
