{"product_id":"greenfield-520-r-vinyl-coated-tri-fluke-river-anchor-20-lb-blue","title":"Greenfield 520-R Vinyl Coated Tri-Fluke River Anchor, 20 lb, Blue","description":"\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Greenfield\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 520-R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e River Anchor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Tri-Fluke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating:\u003c\/strong\u003e Vinyl Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 20 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Boat Length:\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\u003eUPC:\u003c\/strong\u003e 025552520035\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size boats is the Greenfield 520-R anchor designed for?\u003c\/strong\u003e The Greenfield 520-R river anchor is designed to hold boats under 24 feet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 520-R river anchor weigh?\u003c\/strong\u003e The 520-R weighs 20 pounds; Greenfield notes that actual weight can vary slightly since it is a cast iron product, so the listed weight is approximate.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a tri-fluke anchor design good for?\u003c\/strong\u003e A tri-fluke design like the one used on the Greenfield 520-R lets the flukes penetrate soft and moderate river bottoms while also engaging rocks and structure, which makes it effective in rivers and current where a single-fluke anchor may not set well.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 520-R suitable for lake use as well as rivers?\u003c\/strong\u003e Yes, the Greenfield 520-R river anchor is described as a good all-purpose anchor for lighter craft and works as a primary or second anchor beyond just river conditions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color and finish does the 520-R come in?\u003c\/strong\u003e The 520-R is finished in blue vinyl coating, which helps protect the boat's hull and finish from scuffs during anchoring and retrieval.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Greenfield 520-R anchor made from?\u003c\/strong\u003e The 520-R has a tri-fluke cast iron construction with a protective vinyl coating over it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat scope ratio should I use with the 520-R anchor?\u003c\/strong\u003e Greenfield recommends a scope ratio of 5:1, meaning 5 feet of line for every 1 foot of water depth, when anchoring with the 520-R.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 520-R be used as a secondary anchor?\u003c\/strong\u003e Yes, the Greenfield 520-R is recommended as a great all-purpose anchor for lighter craft or as a second anchor on larger boats.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the vinyl coating on the 520-R protect my boat?\u003c\/strong\u003e Yes, the vinyl coating on the Greenfield 520-R is designed to protect the boat's finish from scratches and scuffs caused by the anchor during handling.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat conditions is the 520-R best suited for?\u003c\/strong\u003e The Greenfield 520-R is recommended for soft to moderate bottom conditions and medium duty use, particularly in rivers and current where its tri-fluke design can engage rocks and structure.\u003c\/p\u003e","brand":"Greenfield Products","offers":[{"title":"Default Title","offer_id":49031103676635,"sku":"G-P-520-R","price":131.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51JmhVsoFXL.jpg?v=1785208902","url":"https:\/\/www.goodvibesmarina.com\/products\/greenfield-520-r-vinyl-coated-tri-fluke-river-anchor-20-lb-blue","provider":"Good Vibes Marina","version":"1.0","type":"link"}
