Lightweight anchors that hold strong
Holding power and weight usually trade off, but Fortress Marine Anchors break that rule with high-strength aluminum anchors that hold strong while weighing far less than comparable steel anchors. Made from corrosion-resistant aluminum alloy, Fortress anchors are prized for excellent holding in sand and mud, easy handling thanks to their light weight, and a clever adjustable fluke angle that you can set for harder or softer bottoms. They also disassemble for storage. For boaters who want strong holding power, easy handling, and a great storm or secondary anchor, Fortress is a proven, respected choice that punches well above its weight.
Choosing the right Fortress comes down to your boat and bottom. Fortress publishes sizing by boat length and weight, so match the anchor model to your boat for adequate holding. Set the adjustable fluke angle to suit your bottom, a standard angle for sand and a wider angle for soft mud, which makes a real difference in holding. Pair the anchor with proper rode and chain. Consider one as a primary, storm, or secondary anchor. Review the product details and Fortress sizing chart before buying. With a Fortress anchor, you get strong, lightweight holding power.
