Greenfield Products 516-RD Vinyl Coated Tri-Fluke River Anchor, 16 lb, Red

The Greenfield Products 516-RD is a 16 pound tri-fluke river anchor built for boats under 18 feet. Its tri-fluke cast iron design is engineered to penetrate soft and moderate river bottoms while also engaging rocks and structure in current, making it effective in the changing conditions found in rivers and moving water. This design makes it a solid all-purpose anchor for lighter craft, and it also works well as a second anchor aboard larger boats.

The anchor is finished with a vinyl coating that protects the boat's finish from scuffs and scratches during handling and stowage, and the coating is applied in red for easy visibility on deck or in a locker. For anchoring in typical river and current conditions, a recommended scope of 5:1 (line feet to depth feet) is advised to keep the flukes set. Because the anchor is cast iron with a vinyl coating, actual weight can vary slightly from the listed 16 pounds due to differences in metal and coating content.
