 This marked the first time in the nations history that all functions of maritime safety came under one agency.The Marine Safety program is still administered by the Coast Guard, an agency originally under the control of the United States Department of the Treasury, later under the control of the United States Department of Transportation, and now under the control of the United States Department of Homeland Security.In an attempt to promote better service to the maritime industry as well as the general public, the marine inspection and Captain of the Port/port safety functions were combined.
