During her shakedown cruise, the gunboat called at St. Thomas, Virgin Islands; San Juan, Puerto Rico; and Guantanamo Bay, Cuba, before heading north for Norfolk, Virginia.

From 30 July to 13 August, she took part in Fleet maneuvers off New River, North Carolina; voyaged to Bermuda in October; and cruised to Argentia, Newfoundland; and Casco Bay, Maine, before returning to New London on 6 December - the day before Japan's attack on Pearl Harbor.

Calling at Portland, Maine; New London; Philadelphia; New York City; Norfolk; Portsmouth, New Hampshire; Bermuda; the Dominican Republic; Trinidad; Curaçao - the ship's itinerary showed clearly that Ingersoll had mobility and was utilizing it to the fullest.

Ingram, who had so successfully conducted United States-Brazilian relations during the period when he commanded American naval forces in the South Atlantic, would fly his flag in the gunboat through the end of hostilities.

She was taken to Pireus in Greece where she was rebuilt from the hull upwards and turned into the Argonaut, a luxury cruise ship under charter to Raymond Whitcombe, touring, amongst others, places such as the Mediterranean, Caribbean, and the Fjords of Norway.

In 1995 she was sold to Memnon Tours of Cairo, Egypt, and renamed Regina Maris, operating a seven-night cruise in the Red Sea, and later in 2001, the Mediterranean, under charter to Phoenix Reisen of Germany.
