Unlike anchors designed only for soft mud, the tri-fluke design is engineered to penetrate soft and moderate river bottoms while also engaging rocks and structure, giving it more versatile holding performance in moving water than a single-purpose anchor style. The cast iron body is protected by a vinyl coating that helps prevent the anchor from scratching or marking the boat's hull and finish during retrieval and stowage.\u003c\/p\u003e\u003cp\u003eWeighing 16 pounds, the 516-R is well suited as a primary anchor for lighter craft or as a second anchor aboard larger boats, such as for stern anchoring in current. For proper holding, a recommended scope ratio of 5:1 (line feet to depth feet) should be used. Because the anchor is cast and coated, actual weight can vary slightly batch to batch, with 16 pounds representing the listed and approximate weight for this size. The Royal Blue vinyl finish provides a durable, corrosion-resistant coating over the cast iron fluke and shank.\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 516-R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e River Anchor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAnchor Style:\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:\u003c\/strong\u003e Royal Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 16 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Boat Length:\u003c\/strong\u003e Under 18 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 025552516038\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size boats is the Greenfield 516-R river anchor designed for?\u003c\/strong\u003e The 516-R is designed to hold boats under 18 feet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 516-R river anchor weigh?\u003c\/strong\u003e This river anchor weighs 16 pounds, with actual weight able to vary slightly since it is a cast and coated product.\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 516-R allows the flukes to penetrate soft and moderate river bottoms while also engaging rocks and structure in rivers and current, making it more versatile than a single-purpose anchor in moving water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 516-R river anchor made from?\u003c\/strong\u003e The 516-R is made from cast iron with a vinyl coating over the body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy is the anchor vinyl coated?\u003c\/strong\u003e The vinyl coating on the 516-R protects the boat's finish from scratches or marks when the anchor is being retrieved or stowed.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 516-R river anchor?\u003c\/strong\u003e The 516-R river anchor has a Royal Blue vinyl-coated finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat scope ratio should I use with this anchor?\u003c\/strong\u003e A recommended scope ratio of 5:1 (line feet to depth feet) should be used with the 516-R river anchor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 516-R be used as a second anchor on a larger boat?\u003c\/strong\u003e Yes, the 516-R is a good all-purpose anchor for lighter craft and also works well as a second anchor, such as for stern anchoring in current on larger boats.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 516-R suited for muddy or rocky river bottoms?\u003c\/strong\u003e The tri-fluke design of the 516-R is recommended for soft to moderate bottom conditions and is built to engage rocks and structure typically found in rivers and current.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the listed weight of the 516-R vary?\u003c\/strong\u003e Yes, because the 516-R is a cast iron anchor with a vinyl coating, actual weights can vary due to metal and coating content, so 16 pounds is the listed approximate weight.\u003c\/p\u003e","brand":"Greenfield Products","offers":[{"title":"Default Title","offer_id":49031103578331,"sku":"G-P-516-R","price":45.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51xUniNRGLL.jpg?v=1785208899","url":"https:\/\/www.goodvibesmarina.com\/products\/greenfield-products-516-r-vinyl-coated-tri-fluke-river-anchor-16-pounds-royal-blue-for-boats-under-18-feet","provider":"Good Vibes Marina","version":"1.0","type":"link"}
