NTSB – shared waterway safety
The National Transportation Safety Board (NTSB) issued a Marine Safety Recommendation regarding safety of recreational and commercial vessels in shared waterways of the marine transportation system (MTS). The report recommends, among other things, that the US Coast Guard establish a process whereby, at regular intervals, all harbor safety committees identify the safety risks posed by the interaction of commercial and recreational vessels in their respective geographic areas and, when necessary, develop and implement practices to mitigate those risks.
