Presumably there is some slack in the anchor chain, and how much slack would determine how far the buoy could move in any direction. I suppose it would depend on the depth of the water and the tidal range and perhaps the strength of the current in the area. What is a typical radius of the resulting circle of position? Ten yards? Fifty yards? Chuck Taylor SEASCAPE GB 32-2 Everett, WA, USA
