The Legendary Fortress Anchor In test after test, from coast to coast and from around the world, no anchor in history has been called "The Worlds 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.
