About National Maritime Day
President Franklin Delano Roosevelt signed Public Law 105-225 designating May 22 as National Maritime Day in 1933, in §128.
On this date in 1819, the steamship SS Savannah set sail on the first trans-Atlantic voyage entirely conducted under steam power. The day is marked in law to recognise that event, and fallen mariners in the United States Merchant Marine. The date is a full-staff day.
NS Savannah (the world’s only nuclear-powered merchant ship, named after the famous steamship) is currently docked in Baltimore, MD., is where events marking the day usually take place.
All government agencies are directed to fly the flag on National Maritime Day. All ships and boats registered under the American flag should dress ship. All citizens are encouraged to fly the flag on National Maritime Day.
