🇺🇸 Washington, United States

Washington, D.C., the capital of the United States, is not located on the coast and does not have any ports or shipyards. However, it is home to important government institutions, including the Department of Transportation and the United States Coast Guard headquarters, which may be of interest to seafarers, shipowners, and crewing companies. Additionally, the city's proximity to the Chesapeake Bay and the Potomac River offers opportunities for recreational boating and water activities.
