Mary A. Whalen, known as the S.T. Kiddoo from 1938 to 1958, is a historic oil tanker located in the Red Hook neighborhood of Brooklyn, Kings County, New York. She is the home of the non-profit PortSide NewYork, and the group runs programs aboard her. She was built in 1938 by the John J. Mathis Company, of Camden, New Jersey Hull #124, and measures 172 feet long.[2] She is a rare surviving example of a "bell boat," a ship controlled from the engine room with telegraph signals sent from the bridge.[3] The tanker shipped various fuel products along East Coast and was at center of United States v. Reliable Transfer Co., a pivotal 1975 Supreme Court decision in maritime law after she ran aground in Rockaway Inlet in 1968. She was in active service until 1994.[4]
She was listed on the National Register of Historic Places in 2012.[1]
