Unrivalled Harbor Expertise
in East Boston
Expertise, coordination, and communication are vital components of Boston Harbor pilots’ work, from planning the leap across open water to warning recreational boats out of the shipping channel.

The Boston Pilot boat and tanker travel side-by-side at identical pre-arranged speed and direction. When the pilot judges the alignment to be optimal, he jumps to the hanging ladder and climbs aboard.
By law, all ships over a certain size—fuel tankers, container ships, even luxury yachts—must have a commissioned pilot on board to enter the harbor. Boston’s eight pilots hold “Unlimited Ocean Master” licenses issued by the Coast Guard; they can command any size vessel. Their decades of experience and intimate knowledge of the harbor’s underwater landscape, tides, and currents enable them to bring every ship to dock safely. They work alternating weeks and are available every hour every day—in all weather.
Ship captains—and ship owners—recognized centuries ago the value of having on board a mariner with knowledge of local conditions. In 1783, the Boston Marine Society, an association of sea captains, advocated for “the establishment of a regular, skillful system of pilotage” in Massachusetts. For decades thereafter they managed the pilots. Today, two governor-appointed commissioners oversee the service that protects the environment and commercial shipping.
The Boston Pilot boats bring pilots about 10 miles off shore, where they board incoming vessels, give compass and speed instructions, and ensure ships stay within the main shipping channel. Some ships approach through The Narrows, the original entrance to Boston Harbor that threads its way around islands and shoals.

For decades, schooners served as the harbor’s pilot boats, ferrying pilots beyond the lighthouses to board incoming ships. In 1941, the Boston Pilots Association bought the Roseway, the last schooner to serve as a pilot boat for Boston Harbor. She filled that role until 1973.
