RedactedNarrative: In the above date and time, I was on Patrol at Lake Pleasant in a marked MCSO Patrol Boat.  While on patrol I was contacted by Peoria Fire about a boat that was drifting freely in Humbug Cove.  
  
  I proceeded to the location where I was flagged down by Owner#2.  Owner#2 is the owner of vessel two.  Owner#2 advised he and his party were tied up with other boats in Humbug Cove.  While they were all in the water swimming they heard a loud thud.  When they investigated, they found an unoccupied vessel 1 had drifted into his vessel.  Owner#2 said his 1997 Euro Sport suffered a crack in the side and it would cost $10000 to repair. Neither Owner#2 nor anyone around the area could tell me how the two vessels collided.  
  
  I also spoke with Owner#1, owner of vessel 1.  Owner#1 said he had been away from his boat, when he returned, he found it had drifted free and was tied on to vessel 2.  Owner#1 stated he believed his 1997 SeaRay had gotten free because someone had untied the vessel.  He had no idea about damage to his vessel due to not being able to see the area.
  
  On this day, Humbug Cove was very crowded and loud.  Due to the confusion in the area I was unable to move the vessels or see the damage.  Additionally there was no one in the area that had observed the contact.
  
  NOTHING FURTHER.
