cardinal marks
Waterways are categorized into one or more of the following:
Miltitary critical waterways- which serve the military.
environmentally critical waterways- where a degradation of the aids to navigation system would present an unacceptable level of risk to general public safety or to the environment.
Navigationally Critical Waterways:Waterways where degradation of the aids to navigation system would result in an unacceptable level of risk of a marine accident, due to the physical characteristics of a
waterway, difficult navigation conditions, aid establishment difficulties, or high aid discrepancy rates.
non critical waterways: Waterways serving commercial and recreational interests, where the disruption or degradation of an aids system, beyond the normal level of discrepancies, will not increase the risk of a marine accident to an unacceptable level
What is aid availability?
