Fortress marine anchors weigh only half as much as heavier steel anchors and yet outperforms them all. Why? Fortress 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 can be 50% heavier or more.
Capitalizing on years of Fortress Anchor R & D, Guardian anchors offer excellent quality, performance and economy. Guardian is made from the same high tensile, corrosion resistant aluminum magnesium alloy and manufacturing precision as Fortress. The use of slightly smaller extrusion profiles and the elimination of some of Fortress™ extra features, such as anodizing, adjustable fluke angles, and several machining steps have resulted in a very affordable alternative to those heavy, rust-prone steel anchors. Guardian anchors are also light, rustproof, second only to the Fortress marine anchor in holding power tests, and an affordable alternative to heavy steel anchors.
