The Tri-Fluke design of the River Anchor allows the flukes to penetrate the river bottom in soft and moderate conditions, or to engage rocks and structure in rivers and current. The River Anchor is a great, all purpose anchor for lighter craft, or a great second anchor. Larger models are the preferred choice for pontoon boats and other difficult to hold boats. Greenfield recommends use in soft/moderate conditions or structure and for light/medium duty.
PVC coated anchors are designed for better penetration than mushroom anchors. Flukes will catch and hold to bottom where rocks and stumps are common. This anchor is 30 pounds and works for boats up to 26 feet.
