U.S. Naval Academy Freshmen, known as plebes, participate in "Sea Trials" at the Naval Academy in Annapolis, Md., May 17, 2005. "Sea Trials" is an 11.5 hour action-oriented event, modeled after the U.S. Marine Corps' 54-hour "Crucible" and the Navy's "Battle Stations" training tests, which requires plebes to use skills they have learned during their first year at the Naval Academy.
