Today
Boston Light was automated in 1998, but is still staffed by a resident civilian keeper assisted by volunteer watchstanders from the Coast Guard Auxiliary. However, these personnel are mostly used to act as interpretive tour guides for visitors.
Its light, flashing white every 10 seconds, shines through the only second-order Fresnel lens still in use in Massachusetts (of only four total), and is visible from a distance of 27 nautical miles (50 km). Although it is still an important navigation mark, its importance has been decreased over the last century by the use of Boston Harbor's North Channel for most large vessels entering the harbor.
Guided tours of the island and light are available, by prior arrangement.
