Unlike a simple fluke anchor, the tri-fluke cast iron design is engineered to penetrate soft and moderate river bottoms while also engaging rocks and structure that a boat may encounter in moving current, giving it more versatility than a single-purpose anchor. The entire anchor is finished with a black vinyl (PVC) coating that protects the boat's hull and finish from scuffs and scratches during retrieval and stowage.\u003c\/p\u003e\u003cp\u003eAt 20 pounds, the 520 is sized for boats under 24 feet, making it a solid primary anchor for lighter craft or a dependable second anchor aboard larger boats. For proper setup, a scope ratio of 5:1 (line feet to depth feet) is recommended to ensure the flukes set and hold securely. Its compact tri-fluke shape allows it to store easily in ski lockers or under back-to-back seating when not in use.\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnchor Design:\u003c\/strong\u003e Tri-Fluke\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Cast Iron, Vinyl Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Finish:\u003c\/strong\u003e Black (PVC Coated)\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 025552520011\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size boat is the Greenfield 520 river anchor designed for?\u003c\/strong\u003e The Greenfield Products 520 is a 20 lb river anchor designed to hold boats under 24 feet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Greenfield 520 anchor made of?\u003c\/strong\u003e It is a cast iron tri-fluke anchor finished with a black vinyl (PVC) coating that protects the boat's hull and finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the tri-fluke design on the 520 anchor do?\u003c\/strong\u003e The tri-fluke design lets the Greenfield 520 penetrate soft and moderate river bottoms while also engaging rocks and structure encountered in rivers and current.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWill the anchor scratch my boat's hull?\u003c\/strong\u003e No, the Greenfield 520's black vinyl coating is applied specifically to protect the boat's finish from scratches during handling.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat scope ratio should I use with this anchor?\u003c\/strong\u003e A scope ratio of 5:1 (line feet to depth feet) is the recommended setup for the Greenfield 520 river anchor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Greenfield 520 anchor weigh?\u003c\/strong\u003e The Greenfield 520 river anchor weighs 20 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 520 anchor good for rocky river bottoms?\u003c\/strong\u003e Yes, the tri-fluke design of the Greenfield 520 is built to engage rocks and structure in rivers and current, not just soft or sandy bottoms.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this be used as my only anchor, or just a backup?\u003c\/strong\u003e The Greenfield 520 works as a primary anchor for lighter craft under 24 feet, and it also serves well as a second anchor aboard larger boats.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the Greenfield 520 anchor?\u003c\/strong\u003e The 520 is finished in black with a PVC vinyl coating over its cast iron body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 520 anchor suitable for lake use as well as rivers?\u003c\/strong\u003e The Greenfield 520 is designed as a river anchor, engineered to grip soft-to-moderate bottoms and engage rocks and structure in current, which also suits general all-purpose anchoring use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the tri-fluke design differ from a standard fluke anchor?\u003c\/strong\u003e Beyond penetrating soft and moderate bottoms like a standard fluke anchor, the Greenfield 520's tri-fluke shape is also designed to catch and hold on rocks and structure found in river current.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere can I store the Greenfield 520 anchor on my boat?\u003c\/strong\u003e Its tri-fluke shape allows the Greenfield 520 to store easily in ski lockers or under back-to-back seating.\u003c\/p\u003e","brand":"Greenfield Products","offers":[{"title":"Default Title","offer_id":49031103643867,"sku":"G-P-520","price":81.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51MOsRFvi8L.jpg?v=1785208900","url":"https:\/\/www.goodvibesmarina.com\/products\/greenfield-products-520-20-lb-vinyl-coated-tri-fluke-river-anchor-for-boats-under-24-feet","provider":"Good Vibes Marina","version":"1.0","type":"link"}
