Greenfield Products 520 20 lb Vinyl Coated Tri-Fluke River Anchor for Boats Under 24 Feet

The Greenfield Products 520 is a 20 lb tri-fluke river anchor built for boaters who need reliable holding power in rivers, currents, and mixed bottom conditions. Unlike a simple fluke anchor, the tri-fluke cast iron design is engineered to penetrate soft and moderate river bottoms while also engaging rocks and structure that a boat may encounter in moving current, giving it more versatility than a single-purpose anchor. The entire anchor is finished with a black vinyl (PVC) coating that protects the boat's hull and finish from scuffs and scratches during retrieval and stowage.

At 20 pounds, the 520 is sized for boats under 24 feet, making it a solid primary anchor for lighter craft or a dependable second anchor aboard larger boats. For proper setup, a scope ratio of 5:1 (line feet to depth feet) is recommended to ensure the flukes set and hold securely. Its compact tri-fluke shape allows it to store easily in ski lockers or under back-to-back seating when not in use.
