Although marine pilots are primarily viewed through the lens of navigation safety, environmental protection, and maritime commerce, they also perform vital maritime security functions. By boarding vessels before they enter U.S. ports and guiding them through domestic waterways, pilots help close critical gaps between foreign-flagged vessels and the domestic maritime system. As we observe the 25th anniversary of the Sept. 11, 2001, terrorist attacks, it is fitting to recognize pilots as a first line of defense safeguarding coastal waters, vital commerce, and critical port infrastructure.
Unlike foreign vessel crews, who are employed by international shipping companies or, in some cases, entities subject to foreign government influence, pilots are licensed by individual states or, for the Great Lakes, by the U.S. Coast Guard. Their responsibilities are grounded in the public interest — the safety and security of local waterways and infrastructure — not in the commercial or governmental interests of a vessel’s operator.
When a pilot boards a vessel, she or he takes command of navigation through local waters, a critical safeguard given that foreign-flagged ships make up over 90% of commercial port calls in the U.S. Because pilots are vetted, credentialed, and background-checked by federal and state authorities, placing them on the bridge helps guard against insider threats, undertrained crews, and hostile intent.
Pilots also serve as additional “eyes and ears” for law enforcement and intelligence agencies. Boarding incoming vessels miles offshore, well before they reach populated areas or inland waterways, puts pilots in a unique position to spot anomalies and provide real-time situational awareness. While the Coast Guard and Customs and Border Protection monitor documentation and intelligence streams, pilots provide firsthand assessments from the bridge — tracking equipment, crew behavior, and structural integrity throughout the transit from sea to berth. They are trained to identify red flags such as unexplained route deviations, erratic crew behavior, mechanical deficiencies, and unreported personnel.
Pilots maintain direct, real-time communication with the Coast Guard, CBP, and port authorities. If a threat emerges, a pilot can alert authorities, coordinate an emergency response, or direct a vessel to stop short of a bridge, refinery, or military installation. A formal memorandum of agreement between the American Pilots’ Association and the Coast Guard formalizes this cooperation, recognizing pilots’ unique awareness and deep understanding of the maritime domain and committing both parties to strengthen port security together.
Today’s threat landscape includes the potential use of a commercial vessel as a weapon. An intentional grounding, allision, or channel obstruction could cripple military ports, paralyze economies, or disrupt supply chains. Pilots mitigate this risk through intimate knowledge of local tides, currents, hazards, and harbor layouts, helping prevent both accidents and deliberate sabotage during a vulnerable phase of transit.
In short, pilots are more than skilled navigators — they are essential participants in America’s maritime security framework. Their independent authority, early detection capabilities, local expertise, and communication networks help insulate domestic ports from international vulnerabilities. As vessels grow larger and geopolitical tensions rise, that security role will only become more vital.
