SS Republic was a sidewheel steamship, originally named Tennessee (also named USS Mobile for a time), lost in a hurricane off the coast of Georgia in October 1865, en route to New Orleans. In 2003, the wreck was located 100 miles off the coast of Savannah, Georgia, and artefacts are on display in selected museums, along with video stories about passengers and crew members.

SS Central America, sometimes called the Ship of Gold, was a 280-feet sidewheel steamer that steamed between Central America and the eastern coast of the United States during the 1850s. Originally named the SS George Law, the ship sank in a hurricane in September 1857, along with 400 passengers and crew and 30,000 pounds of gold, contributing to the Panic of 1857.
