Fortress Anchors



In test after test, from coast to coast and from around the world, no anchor in history has been called ├┤The World's Best Anchor by more boaters and respected marine experts than Fortress...and for good reason.

Years of research and development, high-tech materials and manufacturing and thousands of real world tests are your assurance of performance, quality, and value. Fortress weighs only half as much as heavier steel anchors and yet outperforms them all.

Why? Because the Fortress design does not depend upon weight to provide world class performance. All this adds up to your best value in anchoring safety and convenience.

Anchor Selection & Specifications Guide
Boat size recommendations are for boats of average windage and proportions in 30 knots of wind, average bottom conditions, and moderate protection from open seas. Remember that the loads in 42 knots of wind are twice as much as in 30 knots.

Use 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.
