BOSTON, Mass. — A 26-year-old Topsham man was arrested Saturday in Boston and charged with stealing a boat and then identifying himself to state police as “Peter Pan.”

Derek Ramsay was charged with larceny over $250, breaking and entering into a boat, using a boat without authority, and furnishing a false name, according to a release from Suffolk County District Attorney Daniel F. Conley.

Massachusetts State Police responded just before noon Saturday to assist the U.S. Coast Guard after the owner of a 28-foot Chaparral reported that he had watched from his dinghy as an unknown man boarded his boat and headed along the Charles River toward the Museum of Science.

Troopers arrived at the scene and instructed the operator — later identified as Ramsay — to put the boat in neutral and move to the stern, according to the release.

When troopers asked who the owner of the boat was, Ramsay allegedly said he was. When asked his name, Ramsay allegedly replied, “Peter.” When asked for his last name, he allegedly said, “Pan.”

Police allegedly recovered the boat owner’s wallet from Ramsay, who was arrested. The boat was eventually returned to the owner.

Ramsay was taken to Massachusetts General Hospital because of his erratic behavior, where staff determined his true identity, according to Conley. He was released from the hospital and taken to the Nashua Street jail.

He was later charged in Boston Municipal Court, where a judge set bail at $2,000 and revoked his open bail on unrelated larceny charges. Ramsay’s next court date is August 2.
