Fortress Marine Guardian Anchor

The Fortress Guardian Anchor provides excellent quality and reliable performance, but at a more affordable price. Made from the same high tensile, corrosion-resistant aluminum magnesium alloy and manufacturing precision as Fortress’ top-of-the-line anchors, the Guardian has smaller extrusion profiles yet its efficacy is a competitive yet more affordable alternative to heavier, rust-prone steel anchors. Fortress Guardian aluminum anchors feature mud palms which are designed to allow the anchor set faster in any sea bottom. Mud palms enable the flukes to point more directly to the seabed.


  • Fortress Guardian Anchor’s aluminum alloy composition is as strong as steel, but only half the weight.
  • Easy to manage weight
  • Rustproof
  • An affordable alternative to heavy steel anchors
  • Can be disassembled - Easy to store
  • 1-Year Manufacturer’s Parts Replacement Warranty
  • Made in the USA

Guardian Anchor Selection Guide

Boat size recommendations are for boats of average windage and proportions to 30 knots of wind, average bottom conditions, and moderate protection from open seas. Note that the loads in 42 knots of wind are twice as much as in 30 knots. Use a three-strand nylon line, 6-12 ft of chain, and a minimum if 5:1 scope. A minimum of 6 feet of chain should be used for every 25 feet of water your boat is usually anchored in.
