Greenfield 520-R Vinyl Coated Tri-Fluke River Anchor, 20 lb, Blue

The Greenfield 520-R 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 also engaging rocks and structure in current, making it well suited to rivers and flowing water where a traditional fluke anchor can struggle to hold. It works well as a primary anchor for lighter craft or as a second anchor aboard a larger boat.

The anchor body is finished in a blue vinyl coating that helps protect the boat's hull and finish from scuffs and scratches during retrieval and stowage. Greenfield recommends a scope ratio of 5:1 (line feet to depth feet) for proper holding performance. Because the anchor is cast from iron and coated, actual weights can vary slightly by unit; the listed 20 pound weight is the standard approximate weight for the 520-R.
