On June 3, 2012 at approximately 11:30 AM Vessel 1 was sailing from Highland Park Marina and heading north.  Near Fort Sheridan, Vessel 1 started it''s turn to head back to Highland Park.  During the turn, Vessel 1 caught wind in the main sail pushing it to the leeward side.  The boom for the main sail was tied off to a cleat and was not able to swing free.  Due to the wind and the sea state on the lake that day, Vessel 1 turned onto it''s side.  Once Vessel 1 was on it''s side, water filled the main sail creating additional weight making it impossible to right by the efforts of the crew.  After feable attempts to right Vessel 1, subject called the U.S. Coast Guard (USCG) via VHF radio on channel 16.  
After receiving the report, USCG responded to the scene and rescued all four victims.  USCG took the victims to Highland Park where a ambulance was waiting.  All four victims were taken to the hospital, treated for hypothermia, and released with no further life threatening conditions.  subject returned to Highland Park, and with the help of some friends, was able to right Vessel 1 and sail it back without further incident.
