The search continued Sunday for the last of six regatta competitors still missing in the Gulf of Mexico after their boat capsized, according to AP. The Coast Guard earlier Sunday rescued five crewmates who drifted at sea for 26 hours . Rescuers searched overhead and in the water for the missing sailor, identified as boat safety officer, Roger Stone. The students and another safety officer on board were rescued about 2 a.m. Sunday. The search began around 8:15 a.m. Saturday after the 38-foot (11.5-meter) Cynthia Woods missed a radio check. A helicopter crew from Air Station Houston pulled the five men from the water 23 miles (37 kilometers) south of Freeport, Texas, Petty Officer Renee C. Aiello said Sunday. They had drifted about five miles (eight kilometers) northwest of their capsized boat. They were taken to the University of Texas Medical Branch in Galveston, where all five were listed in good condition. They were suffering from sunburn and dehydration, said R. Bowen Loftin, CEO of Texas A&M University at Galveston. The boat, which lost communication around midnight Friday, was competing in the 40th annual Regata de Amigos. The race, which covers 610 nautical miles (1,130 kilometers) from Galveston to Veracruz, Mexico, started Friday and continues into next week. The crew comprised four college students and two safety officers, Texas A&M at Galveston said in a news release. Coast Guard officials said the keel of the overturned vessel was ripped off, indicating the sailboat may have hit something in the water, according to the school. Race director Kevin Box said the loss of the keel can cause a boat to overturn in seconds. Aiello said a flotation device was found near the boat. The boat went missing 11 miles (18 kilometers) south of Matagorda, which is about 110 miles (180 kilometers) down the coast from Galveston.
