FX-37 Anchor – 21lbFor over three decades, the much lighter Fortress Anchor has out-performed substantially heavier steel anchors in holding power tests conducted all around the world.  In the US Navy tests, not only did the Fortress out-perform heavier steel anchors, they were also able to withstand pull loads that averaged over 200x their own weight. Fortress Anchors are constructed using a high-tensile, corrosion-resistant, aluminum magnesium alloy. This results in a lighter, easy to handle anchor with superior holding power.The anchors have been designed to be easily disassembled for compact storage, or as a spare and\/or a storm anchor.  All Fortress Anchors are precision-machined for sharpness and quick penetration into common sea bottoms, which ensures faster setting-performance.Fortress Marine Anchors offers a 100% Hassle-Free Lifetime Parts Replacement Warranty.*Made in the U.S.A.Features:Award Winning DesignHighest rating in tests worldwideHardened high-tech aluminum magnesium alloyAdjustable fluke angles: 32°  for common bottoms, 45° for soft mudEasily disassembled for easy storageEasy to manage weightTough anodized finishTechnical Specifications:Size of Boat – 46′ to 51′ (14 to 15 M)Style – FlukeMaterial – Aluminum magnesium alloyWorking Load – 3,000lb (1,361kg)Shank Length – 40\
