Greenfield Products 15 lb Vinyl Coated Mushroom Anchor - Black, Part 515

The Greenfield Products 515 is a 15 lb cast iron mushroom anchor finished with a black vinyl (PVC) coating that resists chipping and protects boat surfaces from scuffs during storage and handling. Its mushroom shape settles into the bottom and uses suction plus weight to hold position, making it best suited to soft bottom conditions such as mud or sand rather than rock or heavy current.

This anchor is sized for small craft use: personal watercraft (PWC), canoes, kayaks, and boats under 16 feet, and it also works well as a secondary anchor aboard larger boats. Beyond primary anchoring, it can serve as a drag anchor for fishing in current or as a mooring weight for holding small buoys and markers in place. The compact mushroom design stores easily without the folding flukes or sharp points found on other anchor styles.

For proper holding performance, use a scope (anchor line length to water depth ratio) of 5:1. Because the anchor is cast and coated, individual unit weight can vary slightly from the nominal 15 lb rating due to normal variation in metal and coating content.
