Waypoints are usually given for the deeper
water, but we know from past experience that it is very difficult to follow waypoints through the crossings. The cross currents from the ocean inlet also add to the difficulty of staying in the channel. At lower tides when the
anchor lines for the buoys are slacker, they will be pulled in the direction of the
current, sometimes considerably out of the channel, adding another dimension of difficulty. Half-tide and rising is a good policy for the constantly shoaling inlet crossings, even if they have been recently dredged. The Coast Guard moves the floaters frequently as conditions change. MN
