Lightweight, fast-setting and reliable, this anchor gets fan mail
Fortress anchors let you choose between two shank angles to provide outstanding holding power in two common seabed types-a 32° angle for sand, or a 45° angle for soft mud. Precisely machined interlocking components made from high tensile aluminum-magnesium alloy have no welds to weaken the metal. The alloy is extremely strong, corrosion-resistant, nonmagnetic and light. Fortress anchors disassemble for storage, are easier to handle and lighter on the bow than steel anchors.
- Style: Pivoting aluminum fluke
- Material: High tensile aluminum-magnesium alloy
- Application: Sand and mud
- Pros: Changeable shank/fluke angle for extremely high holding power in hard sand and soft mud. Lightweight and strong. Disassembles for storage.
- Cons: Relatively expensive. Limited holding in grass, rocks or clay
- Warranty: Lifetime parts replacement
Boat size recommendations are for boats of average windage and proportions in 30 knots of wind, average bottom conditions, and moderate protection from open seas. Remember that the loads in 42 knots of wind are twice as much as in 30 knots.
Use three-strand nylon rope, 6-12 ft (2-4 m) of chain and a minimum of 5:1 scope. Also, a minimum of 6 ft (2 m) of chain should be used for every 25 ft (8 m) of water depth. For storm conditions use an anchor one or two sizes larger.
