  8:00 AM – The Tachometer suddenly dropped from 2000 RPM to 0 RPM, although the engine was still running smoothly at 2000 RPM.  Operator checked the engine room and there were 2-3 inches of water in the engine room under the engine.  He could not locate the source of water.  We turned the 4 bilge pumps from Auto to Manual to make sure that they were running continuously.  The bilge pumps were running and keeping up with the water intake, however the level was staying the same.
  8:20 AM – Operator called the Coast Guard by VHF16 to advise them that we were taking on water and requested their assistance.  The CG replied that they were sending a boat out to assist us.
  We continued to trouble shoot the water situation, checking the starboard stabilizer; turning off the engine to see if it was the raw water intake hose to the engine; crawling into the engine room to see if there were any obvious spots where the water was coming in.
  8:45 AM – The Pilot Boat from Brunswick, GA arrived and advised us that they were there to watch over us until the Coast Guard arrived.
  9:20 AM – 10 AM  The Coast Guard arrived in a fast response vessel. They sent over a large P6 pump in a barrel for Operator and passenger on our vessel to secure and operate.  A large wave sent Operator crashing into the 4 ft. bulkhead.  He injured his back and hit his head hard and was temporarily incapacitated.  Operator requested that the CG come aboard to assist Occupant with the pump operation.  The Coast Guard engineer came aboard and could not start the pump.  After about 15-20 minutes he requested assistance from his CG crew.  A second engineer came aboard and he couldn’t start the pump either.  After another 20 minutes, the water in the commissary of the boat had continued to rise and Operator told the Coast Guard engineer that we needed to get off of the boat.
  10:00 AM- 10:15 AM  The two engineers got off the boat and assisted the four passengers, one at a time.  As we left the location in the Coast Guard boat, the Kathy O was sinking and only the top of the bimini on the flybridge was visible.
