The Gypsy (previously known as the Witch and the Wren) is a historic catboat whose home is in Wareham, Massachusetts. She was designed and built in 1900 by Bowdoin B. Crowninshield, as one of four identical sailing vessels, and was designated Crowninshield #149. Her design was influenced by the "Seawanhaka Rule", instituted at the Seawanhaka Corinthian Yacht Club to govern important characteristics of racing boats. She has a spoon bow, low freeboard, and long overhangs rising out of the water fore and aft. Her hull is made of white cedar on an oaken frame, although the top levels have been replaced with cypress.The boat design was commissioned by Charles Henry Davis, who received the Hun, the first of the four boats built. The Witch was the second in the series, and was delivered to Osborne Howes II. (In-laws of Howes purchased the other two.) The Witch was first berthed at the summer house of the Howeses in Yarmouth, Massachusetts, which was called "The Witch House", and used by the family in informal races. She was sold by Howes in 1926, and came into the hands of Edward Barus, who sailed her in the Osterville area. After she was damaged in the New England Hurricane of 1938, she was rerigged from a gaff rig to a Marconi rig. In 1949 the boat, now named Wren, was purchased by Marjorie O'Brien, its present owner, who gave the boat its present name.The boat was listed on the National Register of Historic Places in 2008. It is normally berthed at a dock at 35 Lydia Island Road, and may be seen sailing in Onset Bay.

The Wankinco River is a 7.3-mile-long (11.7 km) river in eastern Massachusetts, United States. It is a tributary of the Wareham River, which drains into Buzzards Bay. Although now spelled Wankinco, it was previously written as Wankinquoah, which may have been derived from Wonqun, meaning "crooked". The river originates at East Head Reservoir, a pond in the Myles Standish State Forest, and flows southwards through various impoundments and cranberry bogs to join the Agawam River near the center of Wareham, Massachusetts, after which it forms the Wareham River, forming Wareham's main harbor with a depth of about 12 feet (3.7 m). During a portion of its course, it serves as the boundary between Carver and Plymouth, Massachusetts.
