Vessel 1 was tied to its dock and hooked up to shore power.  The Operator of Vessel 1 ran the generator for approximately half an hour to charge the batteries on Vessel 1 around 9:00 p.m.  At midnight the Occupants aboard Vessel 1 went to bed with the air conditioner on.  Around 1:30 a.m. two of the Occupants awoke not feeling well.  When one of the ill Occupants went down on one knee, the Operator contacted 911 and evacuated everyone from Vessel 1.  When emergency services arrived all five of the Occupants were tested for carbon monoxide exposure; all Occupants had a measurable amount of carbon monoxide in their system and were transported to the hospital.

Investigation determined that a combination of factors contributed to the carbon monoxide situation: 1)The wind was very calm on the night of the incident which allowed the carbon monoxide from the generator to settle and stay in the area, 2) The Operator had pulled Vessel 1 into the slip with the stern of the vessel facing the seawall which contained the carbon monoxide in one area, and 3) the running air conditioner had pulled the carbon monoxide into the cabin of Vessel 1.
