WARNING-CHANGES TO BUOYAGE AND CERTAIN FIXED MARKS

Navigational aids in this dataset are being amended to the IALA Maritime
Buoyage System (Region B) (see NP 735-Edition 3). The relevant amendments
will be promulgated by Notice to Mariners or by inclusion in a New Edition
but may not be practicable until after changes to many of the aids
concerned have taken place. See also L70 in 5011 for symbols used for
buoys and beacons in the IALA system.
