Marine Navigation Safety harbor pilot
State commissioned harbor pilots in the USA are individually licensed by each state. Every state has their own set of rules and regulations for individual pilots. State pilotage is compulsory and a non-competitive monopoly. The majority of states have a pilot board comprised of government, public, pilot, commercial and environmental interests. State pilot associations are comprised of individually licensed pilots who work together and share expenses. In order for state pilotage to function as a public interest navigational safety monopoly each licensed pilot is placed into a rotation and is required to perform an equal share of work.
Massachusetts is unique, as it does not have a government appointed board for pilotage regulations. Massachusetts has 4 pilot districts and 5 pilot commissioners. Two commissioners (Boston District 1) are appointed by the trustees of the Boston Marine Society and the Governor of Massachusetts appoints Districts 2,3 and 4.

The duty of licensed state pilots are to safely move commerce representing the public interest. What does this all mean? Since state pilots are compulsory and in a rotation required by state rules and regulations no vessel owner, representative or entity can force a licensed state pilot to move a vessel when it is not safe to do so. This does not mean one individual pilot has the ability to shut down port operations. There may even be times when one pilot does not agree with another. For example some pilots in Boston are more comfortable in their abilities to board vessels during inclement weather than others. A state pilot license ensures individual judgment and works well so long as each pilot participates in a revolving rotation. Other Links on Compulsory pilots: American Pilots Association
