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

SUPERIOR DESIGN

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

SUPERIOR PERFORMANCE

Since 1986, the much lighter Fortress have consistently out-performed heavier steel anchors in holding power tests conducted around the world. In the US Navy tests, not only did 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.

“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.”

Additional features include:

Fortress anchors can be quickly disassembled for compact storage as a spare or storm anchor.

Fortress anchors let you choose between two shank / fluke angles to provide outstanding holding power in common sea bottoms – a 32° angle for sand, mud or clay, or a 45° angle for soft mud, assuring you of high performance!

Fortress anchors offer a Lifetime Parts Replacement Warranty. In the unlikely event of damaging an anchor part, Fortress will replace the damaged part for free. The only cost to the customer is for shipping & handling, which is nominal.

NOTE: Hard sand holding power figures above represent loads actually achieved on production Fortress and Guardian anchors under controlled horizontal pull conditions without dragging or resulting in disabling structural deformation.

** Rope recommendations are based on manufacturer’s ratings of 25% of breaking strength. Rope must be in good condition.
