Its mushroom shape settles into soft bottom conditions and creates suction-based holding power, making it a dependable choice for light-duty anchoring rather than high-load holding in hard or rocky bottoms.\u003c\/p\u003e\u003cp\u003eThis anchor is sized for small craft, personal watercraft (PWC), canoes, and kayaks, and it also works well as a second anchor aboard larger boats. Beyond primary anchoring, the 508 doubles as a drag anchor for fishing in current and can be used to hold small buoys or markers in place. It is designed for boats under 10 feet and has a working weight of 7 to 8 pounds, with a recommended scope (anchor line length to water depth) ratio of 5:1. Because weights can vary slightly with metal and coating content, listed weight is approximate.\u003c\/p\u003e\u003cp\u003eBuilt from solid cast iron for long-term durability, the black vinyl coating helps resist scuffing on hulls and decks and reduces the risk of rust transfer compared to bare cast iron. It is best suited to calm to moderately soft conditions and light-duty use rather than heavy current or rocky seabeds.\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 508\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 (PVC), Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Weight Range:\u003c\/strong\u003e 7 to 8 pounds\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\u003eRecommended Boat Length:\u003c\/strong\u003e Under 10 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 025552508019\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size boat is the Greenfield Products 508 mushroom anchor designed for?\u003c\/strong\u003e The Greenfield Products 508 is designed for boats under 10 feet, making it suited to small craft such as kayaks, canoes, and personal watercraft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does this anchor weigh?\u003c\/strong\u003e The Greenfield Products 508 has a working weight of 7 to 8 pounds; listed weight is approximate since it can vary slightly with metal and coating content.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is this anchor made of?\u003c\/strong\u003e It is made of solid cast iron with a black vinyl (PVC) coating that helps protect against scuffing and rust transfer.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 508 anchor be used on a larger boat?\u003c\/strong\u003e Yes, the Greenfield Products 508 mushroom anchor can be used as a second anchor on larger boats in addition to its primary role on smaller craft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this anchor suitable for holding a boat in current?\u003c\/strong\u003e The 508 mushroom anchor is recommended for soft conditions and light-duty holding; it also works well as a drag anchor for fishing in current rather than as a primary anchor in strong current.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat scope (line-to-depth ratio) should I use with this anchor?\u003c\/strong\u003e A scope ratio of 5:1 is recommended for the Greenfield Products 508, meaning 5 feet of anchor line for every foot of water depth.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I use this anchor to hold a buoy or marker in place?\u003c\/strong\u003e Yes, the 508 mushroom anchor is suitable for holding small buoys or markers in addition to anchoring small craft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the vinyl coating wear off over time?\u003c\/strong\u003e The black vinyl (PVC) coating on the Greenfield Products 508 is applied over cast iron to resist scuffing and reduce rust exposure during normal anchoring use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat bottom conditions work best with a mushroom anchor like this one?\u003c\/strong\u003e Mushroom anchors such as the Greenfield 508 perform best in soft bottom conditions, where the shape settles in and creates holding suction, rather than hard or rocky bottoms.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Greenfield 508 a good fit for kayaks and canoes?\u003c\/strong\u003e Yes, the 508 mushroom anchor is sized and weighted specifically for small craft including kayaks, canoes, and personal watercraft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat comes with the anchor?\u003c\/strong\u003e The Greenfield Products 508 is the mushroom anchor itself, cast iron with a black vinyl coating; anchor line is not included.\u003c\/p\u003e","brand":"Greenfield Products","offers":[{"title":"Default Title","offer_id":49031103283419,"sku":"G-P-508","price":26.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51y4ok7Df5L.jpg?v=1785208891","url":"https:\/\/www.goodvibesmarina.com\/products\/greenfield-products-508-vinyl-coated-mushroom-anchor-8-pound-cast-iron-black","provider":"Good Vibes Marina","version":"1.0","type":"link"}
