Vessel 1 was sailing in the Northwest Part of Lake Hefner.  A strong gust of wind blew the Catamaran on it's side.  The two adults attempted to upright the vessel, but were having problems.  The two children started drifting away, so the adults left the Vessel to swim to the children.  All four were wearing life jackets prior to the accident (although it is believed the pfd's the children were wearing were too large). The adults removed their PFD's because they thought it would help them in flipping the Vessel back over.  The two children and the passenger were rescued but the owner passed away.
