The USS Hibiscus was a light-draught twin-screw steamer constructed during the American Civil War, designed for naval patrol and blockade duties along the Confederate waterways. Built for the Union Navy, she was purchased in New York City from S. M. Pook on November 16, 1864, and commissioned there on December 29, 1864, under the command of Lt. William L. Martine. Her construction was notable for its innovative design by Samuel H. Pook of Fair Haven, Connecticut, emphasizing a light draft capable of navigating shallow waters while carrying a heavy battery. The vessel was equipped with Wright’s segmental engines, which allowed her to achieve a speed of approximately eleven knots with about 25 pounds of steam pressure during trials conducted in November 1864. Her mean draught was remarkably shallow at 6 feet 7 inches, with a maximum draft of 6 feet 10 inches aft and 4 feet 4 inches forward, even with full bunkers of coal, enabling her to operate effectively in shallow Confederate-influenced waters. The Hibiscus departed New York on January 29, 1865, reaching Tampa, Florida, via Port Royal, South Carolina, and Key West by February 17. She primarily patrolled the Tampa area, including Cedar Keys and St. Andrews Bay, until July 1865. Notably, on April 11, 1865, off Crystal River, her tender Sea Bird captured two small Confederate sloops, Florida and Annie, with cargos of cotton, highlighting her role in enforcing Union blockades. Following the Civil War’s conclusion, Hibiscus returned north, arriving in New York on August 11, 1865. She was decommissioned on August 19 and sold on October 5, 1866. The vessel later sank off New Jersey on April 30, 1873, and her wreck, known locally as the Emerald Wreck, is believed to be her final resting place. The USS Hibiscus exemplifies innovative naval engineering tailored for shallow water operations and played a vital role in Union efforts to blockade and control Southern waterways during the Civil War.
