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 replaced a 35 pound Delta anchor with an FX16 Fortress. I got the Delta many years ago when I was young and spry; now at 68 I'm not so young although I'm still rather spry. So far I'm very disappointed and glad the ole Delta is still in my garage. My 30 foot sailboat sits right smack dab in the middle of the boat length specified by Fortress for this anchor. It is affixed to 30' of chain. On my first set the wind switched direction and shifted 180 degrees and the anchor did not hold in about 15 knots of wind. So I moved to a new location and tried another set and could not get it to set. I know the ground was rocky in the first location but I hooked it with about 6:1 scope and even put on a mask, fins, and snorkel to check the set. Not sure what the bottom was on my second attempt but suspect it may have been rocky also. In thirty years of using the ole Delta I never, not once, had it drag and so far I'm 0 for 2 with the Fortress.

      Comments about Fortress Aluminum Anchors:

      I have a 35ft contender and the anchor locker is not large enough to hold the next size up fortress. I purchased the 7lb fortress which is rated for up to a 32ft boat. Well I'm 3ft over th recommended length and you can not tell. It hooks up almost instantly and holds like nothing else. Amazing anchor that I can't say enough about!

          Switched from a big galvanized 12 lb anchor with a 10 ft chain to this 4lb anchor with a 5 foot chain and I am impressed. It held my 4 thousand pound Parker offshore in 5 ft seas. Even though the chain is short I couldn't tell. Excellent holding power and super lightweight with a strong design.
