Fortress Marine Aluminum Fluke Anchor

Fortress Anchors are often considered the "World's Best Anchors" by boaters and marine experts alike. That is due to their strong yet lightweight properties. Fortress anchors weigh far less than heavier steel anchors and yet outperforms them. Precision-machined from a high-tensile, corrosion-resistant, aluminum magnesium alloy Fortress anchors are sharper than conventional steel anchors. This feature enables Fortress marine anchors to penetrate faster and deeper into most common sea bottoms than heavier, dull-edged traditional steel anchors that weigh at least 50% more than the Fortress anchor.

Key Features:

  • Constructed from a precision-machined, lightweight aluminum alloy that is as strong as steel.
  • Features tough, durable, corrosion-resistant anodized finish.
  • Rustproof, and sharper than heavy, dull-edged steel anchors
  • Sets faster and penetrates deeper into common sea bottoms for superior holding power
  • Disassembles for storage
  • Excellent as a spare or storm anchor
  • Fortress anchors feature a Lifetime Parts Replacement Warranty
  • Fortress marine anchors are available in two shank / fluke angles to provide outstanding holding power in common sea bottoms – a 32° angle for sand, mud or clay, or a 45° angle for soft mud.

NOTE: Boat size recommendations factor 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.

Why Fortress?

The Fortress Advantage

  • Perhaps the best recommendation for Fortress marine anchors is from the U.S. Navy which testing leading anchors. Their results proved that Fortress anchors out-performed much heavier steel anchors, that Fortress anchors withstood pull loads that averaged over 200 times their own weight ... without serious damage to the anchors.

Stronger Holding Power

  • For over 20 years and in test after test, Fortress marine anchors have out-performed substantially heavier steel anchors in holding power tests conducted around the world. From older, well-established anchor brands like the Bruce, CQR, Danforth, or Delta to newer anchors like Manson, Rocna, Spade, and Ultra, the Fortress anchor has consistently demonstrated that its superior design and lightweight alloy can provide outstanding performance at a fraction of the weight.

Faster Setting

  • Easy handling aluminum alloy Fortress anchors are precision-machined for sharpness and quick penetration into common sea bottoms, ensuring faster-setting performance.

Lighter Design

  • Precisely machined interlocking components made from a high-tensile, corrosion-resistant, aluminum-magnesium alloy have no welds to weaken the metal and produces superior holding power while creating a lighter, easy to handle anchor.

Quick Assembly and Easily Disassembled 

  • Lightweight, fast-setting and reliable, Fortress marine anchors disassemble quickly for easy storage, which makes them ideal for tight quarters where compact storage is a requisite. Fortress anchors assemble just as quickly, making them an ideal choice for spare or storm anchors. Precision-machined interlocking components made from a high-tensile, corrosion-resistant, aluminum-magnesium alloy have no welds to weaken the metal. Thereby Fortress anchors offer superior holding power while creating a lighter, easy to handle anchor. In the unlikely event that any piece of the anchor becomes damaged, the unique assembly / disassembly feature allows the damaged or missing part of your anchor to be easily accessed for parts replacement.
