How much does the position of a buoy vary from its charted position as a
result of tides and currents? 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?
