Fortress FX-23 Aluminium Anchor – 6.8kg
The Fortress range of anchors have been a trusted part of the CRA lineup for years, and not without reason. These anchors are a seriously good bit of kit when you are needing something lightweight and easily stowable, while maintaining great holding power, and with a sleek anodized finish they don’t look half bad either.
While the sharp aesthetics are a bonus, it’s the performance that really matters—especially when you’re needing that peaceful night’s sleep in the anchorage. Fortress has been in the game since 1986, and that experience shows. Decades of refinement have gone into their design, materials, and manufacturing techniques, all backed by real-world results.
The outcome? An anchor that combines quality, good engineering, and proven performance—earning a pretty high regard with us.
When it comes to performance, Fortress anchors stand out for several key reasons – starting with their materials. Every Fortress anchor is constructed from a high-strength aluminum-magnesium alloy, offering comparable strength to most steels, while being significantly lighter. This alloy is naturally corrosion resistant and tough, and it’s further protected by a durable anodized finish that helps resist corrosion, scratches, and the perils that the seabed throws at it. Large surface-area flukes provide strong holding power, and the adjustable fluke angles—settable at either 32° or 45°—allow you to adapt the anchor to different seabeds for performance. Assembly and disassembly are quick and easy, making storage convenient when the anchor isn’t in use. Additionally, the Fortress features an all-machined, weld-free design. This eliminates potential weak points caused by welds. The result is a lightweight, high-performance anchor that delivers holding power on par with much heavier steel models
