Greenfield 515-RD Vinyl Coated Mushroom Anchor, Red, 15 lb - Cast Iron Anchor for Small Boats, PWC, Kayaks

The Greenfield 515-RD is a 15 pound cast iron mushroom anchor finished with a red vinyl coating. Its mushroom-shaped head is designed to settle into and grip soft bottom conditions such as mud and sand, making it a light-duty anchoring solution for small craft. It is well suited for personal watercraft (PWC), canoes, kayaks, and other small boats, and also works well as a second anchor aboard larger boats. Beyond primary anchoring, the 515-RD can serve as a drag anchor to help control drift while fishing in current, or as a mooring weight for holding small buoys and markers in place.

The cast iron body gives the anchor the mass needed to hold in soft conditions, while the vinyl coating adds a protective, easy-to-identify red finish that helps guard boat decks and hulls from scratches during handling and stowage. Greenfield recommends a scope ratio (length of anchor line to water depth) of 5:1 for proper holding performance. The compact mushroom shape stores easily aboard boats under 16 feet, and the anchor is intended for light-duty use in calm to moderately soft anchoring conditions rather than rocky or hard bottoms.
