The Mystery is a Chesapeake Bay log canoe, built in 1932, by Harry Sinclair in Oxford, Maryland. She measures 34'-7" long, has a beam of 8'-81⁄2" and has a centerboard. She is noted for her very tall masts, is privately owned, and races under No. 8. She is one of the last 22 surviving traditional Chesapeake Bay racing log canoes that carry on a tradition of racing on the Eastern Shore of Maryland that has existed since the 1840s. She is located at Kingstown, Queen Anne's County, Maryland. She was listed on the National Register of Historic Places in 1985.
