USCGC Dexter, was a steel-hulled patrol boat of the United States Coast Guard in commission from 1925 to 1936.

She saw action during World War II patrolling in the Caribbean, based out of Trinidad, on the Atlantic Sea Frontier.

On June 16, 1942, YP-63 (ex-USCGC Dexter) and the coastal yacht Opal rescued 91 survivors from three successive merchant ships sunk by the German U boats: U-126, U-161 and U-502.

It is ironic that this vessel, originally created to enforce prohibition, became the MV Buccaneer, dedicated to providing quantities of booze to her willing customers.

For three years Buccaneer was at a marina on the Little Calumet River being prepared for sinking in Lake Michigan as a dive attraction.
