When Should You Use the 45 Degree Angle Setting on a Fortress Anchor?

Among the unique features on a Fortress Anchors is a 45 degree fluke angle setting for silt and soupy mud in addition to the 32 degree setting that is native to both Fortress and Guardian Anchors. One of the most common questions we get is: “When should you use the 45 degree angle setting?”

Understanding this is important because using the 45 degree angle setting in the wrong conditions could prevent your anchor from setting or holding a set, which could cause your anchor to drag and create some serious safety issues.

Under most conditions, you will want to stick to the 32 degree fluke angle setting. These include hard or soft sand and mud. The 45 degree fluke angle setting should only be used in extremely soupy mud or silt. By extremely soupy, we mean almost liquid.

Some customers mistakenly believe that the 45 degree angle setting would lead to a stronger hold in sand or mud. This is not the case! As stated above, using the 45 degree setting in anything but very soupy mud or silt will lead to a failure to set.
