USRC William H. Seward was a Revenue Cutter Service schooner built in Wilmington, Delaware and purchased in Philadelphia, Pennsylvania for $34,600 in April 1864.

Initially ordered to New York for temporary duty, she was then assigned to Wilmington, North Carolina in July 1864.

On 30 September 1885, her patrol area was extended into the Mississippi River, as far south as "Port Eads and the Passes."

On 13 July 1895 her cruising grounds were "from Mobile, Alabama to West End, Lake Pontchartrain, with occasional visits into the Mississippi River to the Head of the Passes."

She was sold for $1,015 to Lee Kimball, who renamed her Eugenia and refitted her as a merchant barge.
