The Boston Marine Society (est. 1742) is a charitable organization in Boston, Massachusetts, formed "to 'make navigation more safe' and to relieve members and their families in poverty or other 'adverse accidents in life.'" Membership generally consists of current and former ship captains. The society provides financial support to members and their families in times of need; and also actively advises on maritime navigational safety such as the placement of lighthouses and buoys, and selection of Boston Harbor pilots.
The society first formed as a fellowship in 1742, and officially incorporated in 1754. Founders included William Starkey, Edward Cahill, Isaac Freeman, Richard Humphreys, Edward Freyer, Moses Bennet, Jonathan Clarke, John Cullum, Joseph Prince, and Abraham Remmick. In its first century the society conducted meetings at the Concert Hall, Bunch-of-Grapes tavern, and the Sun Tavern. In 1851 it kept an office on Commercial Street and later in the Merchants Exchange. Since the 1980s it has operated from offices in the Boston Navy Yard.
According to maritime historian Samuel Eliot Morison, the society's meetings "were common ground where all Bostonians interested in seaborne commerce met. The secretary describes it in 1811 as 'composed of upwards of 100 former shipmasters who have retired from sea with adequate fortunes, many of whom are largely interested in the insurance offices and as underwriters, and about 50 of the most respectable merchants and shipowners and gentlemen of the highest stations in the commonwealth. The rest of the Society is composed of the more active and younger mariners who still follow the seas as a professional business.' These last were the men who made the name of Boston famous from Archangel to Smyrna, and east by west to the River Plate and Calcutta."
The society has borne responsibility for safe pilotage in the Boston Harbor since the 18th century. "Beginning in 1791 and continuing through the present, the society through its trustees is vested with the authority to appoint Pilot Commissioners, who in turn appoint Boston Harbor pilots." It has also published guides such as the 1832 Rules and Regulations for the Pilotage of the Harbor of Boston.
