Bouker No. 2, originally Robert Rogers, was a tugboat built in 1904 for merchant service in and around the waters of New York City. During World War I, the tug was commissioned into the United States Navy as USS Bouker No. 2 (SP-1275), and continued in naval service (later with the designation YT-30) until 1921. Briefly considered for service as a fireboat in Norfolk, Virginia, she was instead returned to merchant service in 1922 as a tugboat, under the name New York Marine Co. No. 6. She was sunk in collision with a passenger steamer in 1926.
