Fortress Marine Anchor – FX-7 Boats 16′-27′
Fortress Marine Anchors are precision-machined from a hardened aluminum alloy that is as strong as steel, but with only half the weight. In addition to being stronger and lighter than steel anchors, the aluminum Fortress Anchors have sharp edges which allow them to set faster and penetrate deeper into common sea bottoms for incredible holding power. The Fortress also features an adjustable 32 to 45 fluke angle which helps increase holding power in problem soft mud bottoms. Chain not included.

Can the fluke angle be adjusted for different seabed conditions?
Yes, the adjustable 32 to 45 fluke angle helps improve holding power in soft mud bottoms, allowing better performance on challenging seabeds.
Is the anchor rustproof?
Yes, the anchor is rustproof due to its aluminum alloy construction.


Amelia Hunter –
Installed the anchor on my 20-foot boat and it set quickly in soft sand. The adjustable fluke angle helped it grip better than my old steel anchor. Much lighter and easier to handle. No rust even after a few months in saltwater.
Irene Smith –
Felt much more reliable than my previous steel anchor. It holds firm in mud and doesn’t drag. The weight difference makes it easier to manage on the deck. Great for frequent boating in coastal areas.
Joshua Parr –
Works well in typical bottom types. The fluke adjustment was useful during a trip to a muddy inlet. A bit more expensive than steel, but the performance and weight savings justify it.
