If you thought that a boat anchor had to be very heavy and made of steel in order to perform well, you would be wrong. The FX-37 from Fortress Marine Anchors is a lightweight aluminum anchor that was recently put to the test against a variety of other models, and came out on top.
The testers were stunned by the performance of the aluminum Fortress model FX-37. It held over 7,200 lbs., which was 3,000 lbs. greater than the second best anchor in the test. Just as astonishing was the fact that the 22 lb. Fortress FX-37 was 30% lighter in weight. The crew determined that its holding power was similar to what would be needed by a 40' yacht during a hurricane.
The Fortress FX-37 has been used as the primary anchor for many years aboard the US Coast Guard's 40' range of patrol boats. Most recently, it was selected for the brand new 45' Response Boat Medium (RB-M). The USCG also plans to use the Fortress FX-125 on their new 154 foot Sentinel Class patrol boat.
