Mahi Mahi Harbor Cruises & Private Events was started in 2006 on a 55-foot sightseeing boat affectionately known as The Finback. Every day, she carries passengers on scenic tours through the North Shore. Bordered by Salem, Marblehead, Machester-by-the-Sea, Beverly, and the Misery Islands, the sound’s scenic shores are dotted with lighthouses, mansions, and greenery as verdant as a national Shrek convention. Narration helps passengers brush up on their local history as they nosh on fresh meals and sip tropical drinks from the onboard tiki bar. Larger groups can cruise the same waters on the company’s newly refurbished boat, The Hannah Glover, which accommodates up to 150 guests and boasts two bars.
