Mercantile is a two-masted schooner berthed in Camden Harbor, Camden, Maine. Built in the 1914-16 on Little Deer Isle, Maine, she is one of a small number of such vessels still afloat from a time when they were one of the most common cargo vessels of the coasting trade. Designated a National Historic Landmark in 1992, she now serves as a "Maine windjammer", offering multi-day sailing cruises to tourists.
