The Fortress Anchor is precision-machined from an aluminum alloy that is as strong as steel, but only half the weight making it extremely easy to handle. The Fortress Anchor is sharper than heavy, dull edged steel anchors and will set faster and penetrate deeper for incredible holding power. The adjustable 32° to 45° fluke angle is an exclusive, patented feature that dramatically increases holding power in problem soft and mud bottoms.
