Tampa's Odyssey Marine Exploration has won the right to salvage silver from a ship sunk by a German U-boat off Ireland in World War II. The British government hired Odyssey to find the remains of the cargo steamer SS Gairsoppa, torpedoed on Feb. 17, 1941. Of the 32 crew members who made it to lifeboats, only one man survived after reaching the Irish coast after 13 days. Odyssey, best known recently for retrieving treasure from much older wooden sailing ships, has two years to recover the silver from the SS Gairsoppa. After giving a share to the British, Odyssey will get to keep most of the hoard. "We have good location information which suggests a search area that can be completed in approximately 90 days, and we are scheduling this project for summer 2010," Odyssey chief executive Greg Stemm said.
