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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Greenfield Products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 520-RD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e River anchor, tri-fluke design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Vinyl coated cast iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 20 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Boat Size:\u003c\/strong\u003e Under 24 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Scope Ratio:\u003c\/strong\u003e 5:1 (line feet to depth feet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 025552520028\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size boat is the Greenfield 520-RD river anchor designed for?\u003c\/strong\u003e The Greenfield 520-RD is designed to hold boats under 24 feet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this anchor weigh?\u003c\/strong\u003e The 520-RD weighs 20 pounds, though actual weight can vary slightly due to the metal and vinyl coating content.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the tri-fluke design used for?\u003c\/strong\u003e The tri-fluke cast iron design lets the flukes penetrate soft and moderate river bottoms and engage rocks and structure in rivers and current, which is why it is called a river anchor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat scope (line-to-depth ratio) should I use with this anchor?\u003c\/strong\u003e Greenfield recommends a scope ratio of 5:1, meaning 5 feet of anchor line for every 1 foot of water depth, when using the 520-RD.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 520-RD anchor?\u003c\/strong\u003e This model is the red version of Greenfield's vinyl coated river anchor, designated by the RD suffix in the part number 520-RD.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the anchor coated with, and why?\u003c\/strong\u003e The 520-RD has a vinyl coating over its cast iron body, which protects the boat's hull and finish from scratches during anchor handling and stowage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this anchor be used as a second anchor on a larger boat?\u003c\/strong\u003e Yes, the 520-RD is described as a great all-purpose anchor for lighter craft, or a good second anchor on a larger boat.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 520-RD better suited to lakes or rivers?\u003c\/strong\u003e It is built specifically as a river anchor, with flukes meant to grip in current and engage rocks and structure, and it also works in soft to moderate bottom conditions generally.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Greenfield 520-RD made of?\u003c\/strong\u003e The 520-RD is cast iron with a protective vinyl coating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many anchors come in the package?\u003c\/strong\u003e The Greenfield 520-RD ships as a single unit (unit count of 1).\u003c\/p\u003e","brand":"Greenfield Products","offers":[{"title":"Default Title","offer_id":49031103709403,"sku":"G-P-520-RD","price":81.42,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51Lpqx9tYfL.jpg?v=1785208903","url":"https:\/\/www.goodvibesmarina.com\/products\/greenfield-products-520-rd-vinyl-coated-river-anchor-red-20-pounds-tri-fluke-design-for-boats-under-24-feet","provider":"Good Vibes Marina","version":"1.0","type":"link"}
