Fortress Marine Guardian Anchor

Built for strength without the bulk, the Fortress Guardian Anchor is crafted from a corrosion-resistant aluminum-magnesium alloy that’s tough yet lightweight. Its compact profile makes it easier to handle than traditional steel anchors, while still offering serious holding power. Mud palms guide the flukes into the seabed fast, giving you a solid set across a variety of bottoms. Designed with the same precision as top-tier Fortress models, the Guardian skips the extra weight, but not the quality. Whether you're anchoring for a quick break or overnight stay, this anchor stands up to the elements without rusting or dragging you down. Ideal for anyone who wants reliable performance minus the steel upkeep.

Features:

  • 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.
