SAN JUAN, Puerto Rico - Chief Petty Officer Jimmy Greenlee, stationed aboard the U.S. Coast Guard Cutter Eagle, leads crewmembers in preparation for manning the rail as the Eagle transits past Luis Fortuï¿½o, Governor, Commonwealth of Puerto Rico Monday, May 10, 2010. This custom evolved from the centuries old practice of "manning the yards." Men aboard sailing ships stood evenly spaced on all the yards and gave three cheers to honor a distinguished person. Now men and women are stationed along the rails of a ship to render honors when entering a port, or when returning to the ship's homeport at the end of a deployment.
