RedactedNarrative: The operator and passenger were sailing out of the Kenosha Yacht Club onto the waters of Lake Michigan. The wind was NE 15-20 mph and the waves were approximately 2-3 feet. As they began their trip the fog steadily increased and became increasingly difficult for the operator to maintain visual contact with the shore. They sailed between .25 and .50 miles from the shore before heading back toward Simons Island in an attempt to stay upwind and within sight of shore. The operator had inadvertently bore off too much wind and with both the operator and passenger on the starboard side of the boat, along with the wave action the sailboat healed severely and capsized. Both people on board went into the water. With the boat capsized the boat began grabbing wind and blowing downwind. The operator was able to stay with the boat, while the passenger was separated as he struggled with the restrictions of his self-inflated life vest. The operator struggled to right the boat while the passenger was floating just upwind of the boat. The operator eventually righted the boat and realized the rudder had become disengaged from the boat. The boat lost steering without the rudder and went into irons. The operator worked on the rudder and eventually got it reattached. The passenger was still in view and upwind of the sailboat. As the operator raised the mainsheet he realized it had become cleated and immediately caused the boat to capsize again. The operator tried to once again right the boat but was overcome with exhaustion and the beginning stages of hypothermia. At that point the operator saw he had lost sight of the shore and his passenger, the operator then used his hand-held VHF radio to call the USCG for help. The operator and boat eventually washed up on shore, while the passenger was later picked up approximately 100 yards from shore by the USCG. Both were then treated for hypothermia and later released from the hospital around 9:30pm.
