SS American Victory

"Welcome aboard the American Victory Ship! As one of the 4 fully-operational WWII ships in the country, the American Victory ship is a national treasure and true American icon. [...] Come aboard and witness virtually the entire ship including cavernous three-level cargo holds, radio and gyro rooms, hospital, galley, weaponry, steering stations, flying bridge, signaling equipment, wheelhouse, mess halls, crew cabins, lifeboats, the Captain's quarters, cargo equipment and the engine."

Although this ship is considered a maritime museum honoring those who served in the American Merchant Fleet, it does offer cruises around Tampa Bay twice per year. Much more information is available at the website here.
