Greenfield Products 510 Black Coated Mushroom Anchor - 10 Pound Capacity for Kayaks, Canoes, PWC and Small Boats

The Greenfield Products 510 is a cast iron mushroom anchor with a black protective coating, built to hold small watercraft securely in soft bottom conditions. Its inverted-bell shape settles into sand, mud, or silt to create suction-based holding power, making it a reliable choice for light-duty anchoring where a lightweight, easy-to-stow anchor is preferred over a heavier fluke-style design.

This 10 pound anchor is sized for small craft, personal watercraft (PWC), canoes, and kayaks, and also works well as a second anchor aboard larger boats or as a drag anchor for fishing in current. It is suitable for holding small buoys and markers in place. The anchor is recommended for boats under 12 feet in soft anchoring conditions, and stores easily thanks to its compact, rounded profile. A recommended scope ratio of 5:1 (5 feet of line for every 1 foot of water depth) should be used when setting the anchor.

The black coating protects the cast iron body from corrosion and wear during regular use and storage. As with any cast metal anchor, actual weight can vary slightly depending on the metal and coating content, so listed weight is approximate.
