Greenfield Products 520-RD Vinyl Coated River Anchor, Red, 20 Pounds, Tri-Fluke Design for Boats Under 24 Feet

The Greenfield Products 520-RD is a 20 pound vinyl coated river anchor built with a tri-fluke cast iron design for boats under 24 feet. The tri-fluke shape is engineered to penetrate soft and moderate river bottoms while engaging rocks and structure in rivers and current, making it well suited for moving water rather than still water alone. Its versatility also makes it a practical all-purpose anchor for lighter craft or a reliable second anchor aboard a larger boat.

The anchor body is finished with a red vinyl coating that protects the boat's hull and finish from scrapes and scuffs during retrieval and stowage. For proper holding performance, Greenfield recommends a scope ratio of 5:1 (five feet of line for every one foot of water depth). Because the anchor is cast iron with a vinyl coating, actual weight can vary slightly from the listed 20 pounds due to metal and coating content.
