Greenfield Mechanical Slip-Ring Anchor Coated 8 Lb. Royal Blue. Anchor chain should always be used with steel fluke anchors to provide weight necessary to maintain the proper approach angle for setting. Fluke anchors require a scope of at least 5:1 (rope length to water depth) in order to set properly. A 7:1 scope is recommended. The anchor is retrieved by backing your boat directly over anchor which allows the ring to slide to the crown and release the anchor from the opposite direction. Recommended in moderate conditions and for light/medium duty. Weights vary due to metal and coating content. Listed weights are approximate.
