- USRC Thomas Corwin (Wikipedia)
The Thomas Corwin was a revenue cutter of the United States Revenue-Marine and United States Revenue Cutter Service and subsequently a merchant vessel. These two very different roles both centered on Alaska and the Bering Sea. In 1912, Frank Willard Kimball wrote: “The Corwin has probably had a more varied and interesting career than any other vessel which plies the Alaskan waters.”
