Also known as "B" class cutters or the Thetis class, these ships were originally built to help enforce Prohibition by tracking smuggler craft back to their mother ships. This required good seakeeping and long range. Prohibition ended soon after their construction, and they proved adaptable to the escort role during the Second World War. Their twin rudders gave them excellent maneuverability, and two U-boats were sunk by units of this class. They cost about $258,000 each.
