DEPTHS AND AIDS TO NAVIGATION

The channels and depths in this area are subject to frequent change. The buoyage and other aids to navigation are adjusted accordingly. Buoyed channels and anchorages are surveyed regularly but this activity can be less frequent over adjoining sandbanks which are subject to continual change. Passages over sandbanks should only be used with extreme caution as depths less than charted may exist. Within the Port of London Authority area consult London VTS for the latest information.
