Technical Features for Fortress Marine Anchors FX-37 21lb Anchor

Product # FX37

The Fortress Marine Anchors FX-37 Anchor is precision-machined from an aluminum alloy that is as strong as steel, but only half the weight. It has an adjustable fluke angle of about 32° to 45°. This tough Anodized Finish Anchor is rustproof, can easily be disassembled, and is excellent as a spare or storm anchor.

The Exclusive feature of the FX-37 dramatically increases holding power in problem soft mud bottoms. The anchor is sharper than heavy, dull-edged steel anchors and sets faster and penetrates deeper into common sea bottoms for incredible holding power.
