Classic Harbor Line Boston has set sail, opening the 2017 cruising season. For those looking for a truly authentic and intimate boating experience on Boston Harbor, Classic Harbor Line offers two very different and equally enjoyable vessels: Northern Lights, a vintage 1920’s style motor yacht offering sightseeing, sunset, and live music cruises and the beautiful 80-foot historic Schooner Adirondack III, promising an up-front and exhilarating sailing experience like no other. Adirondack III will be in the Parade of Sail and both vessels are running special cruises for viewing the visiting tall ships. Boats set sail throughout the day and evening from May through December.
