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.

              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.

                    Even though the FX series by Fortress are a bit on the pricey side, I'll still give it 5 stars.

                    I purchased the FX-7 as a bow anchor for my Sea Hunt BX22 with T-Top. I make sure to feed the proper amount of rode and it always holds like a steel bear trap. I sure don't fear breezy days anymore.

                    I've yet to drop this anchor and not have it stick. I did put the "mud palm" extensions on which lifts the angle and allows the anchor to grab much easier. I highly recommend putting them on first thing.

                    Some argue its too light but I prefer it since I only have to contend with the weight of my chain and not the weight of a steel anchor as well. Its easy to assemble and very well crafted. The only thing that could top it off is if it were made of polished billet alluminum.

                    What I also like is this anchor can be easily disassembled and stored in the optional canvas pouch. Makes it nice for storage if you have limited anchor storage room.

                    I liked the quality and capabilities so much I picked up the smaller Gardian G-5 to use as a Stern anchor.

                    Get one, if you use it properly, it should last you a long time.

                      After using heavy steel anchors for years, I finally broke down, spent the $$ and bought a Fortress. Once this anchor hits bottom, it digs in amazingly fast and it holds like a concrete mooring!

                      Also, retrieving it is a breeze and a back saver. My only regret is not buying one sooner.
