FORTRESS Fortress Aluminum Anchors

Lightweight, fast-setting and reliable, this anchor gets fan mail

Made of high-tensile aluminum-magnesium alloy with no welds to weaken the metal, Fortress anchors are not only lightweight, they are strong! And they are versatile as well, with two adjustable shank angles: 32° for sand and 45° for soft mud. They are easy to handle and their light weight helps to minimize weight at the bow. Precisely machined, anodized, interlocking components are corrosion resistant, nonmagnetic and as easy to put together as they are to take apart. For compact storage, we suggest one of the bags offered separately on this page. Made in USA. Type approved by the American Bureau of Shipping (ABS). Models FX-37 to FX-125 are certified as Super High Holding Power (SHHP) anchors.

  • Style: Pivoting aluminum fluke
  • Material: High tensile aluminum-magnesium alloy
  • Application: Sand and mud
  • Pros: Extra high holding power. Two shank angles hard sand and soft mud. Lightweight and strong. Disassembles for storage.
  • Cons: Less effective on rocky or grassy bottoms. Light weight makes small sizes “sail” under water if boat is drifting backwards quickly.
  • Warranty: Lifetime parts replacement

My back, shoulders and arms thank Fortress for their Aluminum Achors. I traded my 50Lb steel anchor for the Fortress and I could not believe the difference in not only weight...but the holding power. It also seems to dig in faster in the lake bottom. We don't use a windlass...so it's my back...or if we have quests...I can sometimes get a volunteer to hoist!

I have used almost every type of anchor and owned more than 10 boats in my lifetime. I got a FX11 with my 24 Pursuit I recently purchased and was eager to see how well it works. Fortress ads are really misleading and false. I tried it out on my 13 Whaler ( its rated for 28-32 foot boat) and it is simply junk. Its so light it skips over the bottom even though I had 4 feet of chain on it. I tried it on sandy, muddy, and hard ground. I would not use it for a spare its that bad. Also the construction is very weak and shabby. Save money and buy a good ole steel anchor.

  • Reliable

Cons

    Best Uses

      I used a 7 lbs. Fortress for 7 years on our Catalina 30 sailboat. It replaced a 20 lbs. Danforth steel anchor. I had a 25 lbs. plow type anchor as a back-up. The Fortress was used in sand and mud. This was on Lake Erie. It never failed to hold, but we never anchored on a rocky bottom. My wife and I the light weight the light weight. We did not have a windlass.

        I have used a Fortress anchor on a wide variety of boats here in the Florida Keys over the past 20 years or so and I simply would not be without one. They handle easy, don't rust, and have incredible holding power for their size. If you ever damage an anchor part, they replace it for free, no questions asked.

        Simply follow their chain length and size recommendations and you will be a happy Fortress owner for life.

                    This anchor always sets on every bottom. When it sets in clay I worry it may not come up. It sets on almost every throw. I am looking to get another one as I use one to moor out and only trust this one which leaves me with my back up which is terrible when I go out for a ride. Yes it is pricy but it is reliable and trust it as it has never failed. I use it all the time and it is 15 years old and looks like new today. Chain is showing age and have replaced ropes a few times but anchor is like new and still has a shine to it.

                          Was skeptical as to what made this anchor so great (compared to other Danforth anchors). Picked one up used for [$] and was pleasantly surprised at how well it works. This thing really sticks! I have a 24' pontoon that I take out to the Gulf of Mexico. One of the channels (Boca Grande Pass) has quite the current. It is about 48' deep and when the tide is going in or out it can be raging. Dropped this anchor down and it set immediately and stuck. Held solidly in that current. I then tried the Danforth that came with the boat and it would not set.I had also beached the boat on the shore in that same channel. I tied the bow off to a tree stump on the shore and set the FX-11 off of the stern on the starboard side (current was running from starboard to port) and again, it set and held on the first try. Had to do some work to get the anchor up (thought I may have to leave it there but it finally came up).Well, last weekend I took a friend out on the boat to the same location. Anchor set and held just fine. When we decided to move to another location he UNTIED THE ANCHOR before we pulled it in (he didn't bother to tell me this until he was a the bitter end of 100' of rope) and it's now at the bottom of Boca Grande Pass.I went to West Marine today and bought a new FX-11. It's definitely worth the money in my opinion.
