The Fortress Guardian anchor, model G-85, is offered with specified dimensions and weight for the 16-19 meter boat length range. Weighing 18.16 kg, this model is associated with equivalent iron anchors in the 32-41 kg range.

The Guardian is manufactured from corrosion-resistant, high-strength magnesium aluminum, like the Fortress, and using the same precise manufacturing methods. Relatively smaller profile molds are used, and the Guardian is created by sacrificing the adjustable fluke angle, aluminum anodization, and some features during the manufacturing process of the Fortress anchor.

It is stated that precisely manufactured aluminum is at least as strong as steel but half the weight. The flukes have a 32-degree angle and the surface is not anodized. The product description states it is rust-proof, ranks as the second anchor after Fortress in holding power performance tests, is more economical compared to heavy iron anchors, is defined as a spare storm anchor, and is easy to store.
