{"product_id":"greenfield-products-510-r-cast-iron-mushroom-anchor-10-lb-royal-blue","title":"Greenfield Products 510-R Cast Iron Mushroom Anchor, 10 lb, Royal Blue","description":"\u003cp\u003eThe Greenfield Products 510-R is a 10 pound cast iron mushroom anchor finished in royal blue, built to hold small craft steady in soft bottom conditions such as mud or sand. Its flared, bell-shaped design lets the anchor settle into soft substrate and create suction-based holding power rather than relying on flukes to dig in, which makes it a straightforward, low-maintenance choice for boats under 12 feet, personal watercraft, canoes, and kayaks. It also works well as a second anchor aboard larger boats, as a drag anchor for fishing in current, or as a mooring weight for holding small buoys and markers in place.\u003c\/p\u003e\u003cp\u003eBecause the anchor has no moving parts or flukes to foul, it stores easily and deploys quickly, making it a popular choice for boaters who want a simple, reliable anchoring solution for light-duty use. Recommended scope is 5:1 (5 feet of line for every 1 foot of water depth) to achieve proper holding angle. As with any cast metal product, actual weight can vary slightly due to metal and coating content, and the 10 pound figure listed is the standard approximate weight for this size.\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 510-R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Finish:\u003c\/strong\u003e Royal Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 10 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Scope:\u003c\/strong\u003e 5:1 (line feet to depth feet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Boat Size:\u003c\/strong\u003e Under 12 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Use:\u003c\/strong\u003e Mushroom anchor for small craft, PWC, canoes, kayaks; also usable as a drag anchor or mooring weight for buoys and markers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat boat sizes is the Greenfield 510-R mushroom anchor designed for?\u003c\/strong\u003e The Greenfield Products 510-R is recommended for boats under 12 feet, including personal watercraft, canoes, and kayaks, and it can also serve as a second anchor aboard larger boats.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the 510-R mushroom anchor weigh?\u003c\/strong\u003e The 510-R weighs 10 pounds, though actual weight can vary slightly due to normal differences in metal and coating content.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Greenfield 510-R anchor made from?\u003c\/strong\u003e It is made from cast iron, which gives the mushroom shape the density needed to settle into soft bottom conditions and hold position.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 510-R anchor?\u003c\/strong\u003e This anchor is finished in royal blue, as reflected in the 510-R part number designation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat scope of anchor line should I use with this anchor?\u003c\/strong\u003e Greenfield recommends a 5:1 scope for the 510-R, meaning 5 feet of anchor line for every 1 foot of water depth.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 510-R be used for anything besides anchoring a boat?\u003c\/strong\u003e Yes, the Greenfield 510-R mushroom anchor can double as a drag anchor for fishing in current, or as a weight for holding small buoys and markers in position.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 510-R mushroom anchor work in all bottom conditions?\u003c\/strong\u003e The 510-R is recommended for soft bottom conditions such as mud or sand and is best suited to light-duty anchoring rather than rocky or hard bottoms.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 510-R a good primary anchor for larger boats?\u003c\/strong\u003e It is intended for light-duty use and boats under 12 feet, so on larger boats it is best used as a secondary anchor rather than the primary anchor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the mushroom shape of the 510-R have flukes like a traditional anchor?\u003c\/strong\u003e No, the Greenfield 510-R has a smooth mushroom (bell) shape with no flukes, which lets it settle into soft bottom and store easily without parts that can foul.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy might the actual weight of my 510-R anchor differ slightly from 10 pounds?\u003c\/strong\u003e Weights on cast mushroom anchors like the 510-R can vary slightly because of natural differences in metal and coating content during casting; the 10 pound figure is the standard approximate weight.\u003c\/p\u003e","brand":"Greenfield Products","offers":[{"title":"Default Title","offer_id":49031103381723,"sku":"G-P-510-R","price":28.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51mrWNX2IfL.jpg?v=1785208894","url":"https:\/\/www.goodvibesmarina.com\/products\/greenfield-products-510-r-cast-iron-mushroom-anchor-10-lb-royal-blue","provider":"Good Vibes Marina","version":"1.0","type":"link"}
