Enforcement of boating laws and regulations is the responsibility of the New Hampshire Marine Patrol officers. The USCG has enforcement authority on federally controlled waters.
Boaters must stop when signaled to do so by a law enforcement officer. These officers have full police powers and have the lawful right to stop and board your vessel at any time to check for compliance with federal and state laws.
Most New Hampshire Marine Patrol vessels may be recognized by “N.H. MARINE PATROL” on the vessel. State and federal officers have the authority to stop and board your vessel in order to check that you are complying with the law.
