RedactedNarrative: On July 19, 2014 at approximately 1930 HRS, Florida Fish and Wildlife Conservation Commission responded to a report of a capsized vessel approximately 10 miles due west of Caxambas Pass.  We arrived in the area and located the capsized vessel at approximately 1956.  Visibility was clear with approximately 4? waves and 10 mph wind from the northwest.  City of Marco Island Fire Rescue was already on scene (N 25 53.570 W 81 53.420) and removed 5 people from the water.  Also responding were Sea Tow and the Collier County Sheriff's Office.   While on scene, I observed the capsized vessel (V1) with the anchor line wrapped up in the starboard outboard motor.  V1, a  28' Pro Sport catamaran (FL 9599 LC), was towed in by Sea Tow. 
  
  The purpose of the trip for the day was to test V1 as Operator1 had recently purchased it and completed significant repairs.  Operator1 left a cover off the port transom of V1, expecting the need for more repairs upon return from the trip.
  	
  While fishing, V1 took a large wave to the transom, flooding the port hull through the exposed compartment.	Operator1 attempted to start the motors, but the port motor was partially submerged and would not start.	The starboard motor was not effective in righting the vessel.  The Operator1 attempted to anchor the vessel but it was too rough. Operator1 restarted the starboard motor as the occupants were retrieving the anchor and the anchor line was caught in the starboard motor. The starboard motor stalled and V1 capsized by rolling to port approximately 4 minutes later. All persons on board could swim, but no one was wearing a life jacket.
  
  Operator1 also gave a sworn written statement on Form FWCDLE 208 (See attachments) stating the same.  I inspected V1 and found it to be in good physical shape and all physical evidence supported  account of what occurred.  
  
  Operator1's actions constitute careless operation of V1 by operating in rough sea conditions with a compartment cover removed endangering the lives of himself and his passengers. 
  
  Operator1 has been issued Warning for violation of F.S. 327.33 (2) Careless Operation of Vessel.
