Fortress Marine Anchors deliver professional-grade holding power through high-tensile aluminum alloy construction that matches steel strength at significantly reduced weight. Models span from the 4-pound FX7 to the 69-pound FX125, accommodating vessels up to 150 feet. Adjustable fluke angles optimize performance across varying bottom conditions - 32 degrees for clay, mud, or sand, and 45 degrees for soft mud. Sharp edges enable quick penetration, with proven pull loads exceeding 200 times the anchor's weight. The corrosion-resistant, anodized finish ensures durability, while the disassemblable design simplifies storage. U.S. Navy testing confirms Fortress anchors outperform heavier steel alternatives without compromising structural integrity. Each unit includes a lifetime parts replacement warranty for reliable vessel security.

NOTE: Boat size recommendations factor in average windage and proportions in 30 knots of wind, average bottom conditions, and moderate protection from open seas. Also, note that loads in 42 knots of wind ‘weigh’ twice as much as in 30 knots.
We recommend using a three-strand nylon rope, 6-12 ft (2-4 m) of chain, and a minimum of 5:1 scope. Also, a minimum of 6 ft (2 m) of chain should be used for every 25 ft (8 m) of water depth. For storm conditions use an anchor one or two sizes larger.
