RedactedNarrative: We arrived on scene at the mouth of Navajo Canyon near buoy 9C and found an Aramark rental houseboat A13 circling the mouth of the canyon.  Winds at that timer were 20mph with gusts in the 30mph range and 2 to 3 foot seas.  I located the capsized vessel on the northwest canyon wall still floating but banging up against the canyon wall with each wave.  Over marine band radio I contacted the operator of houseboat A13 and confirmed that all their party was accounted for and no persons were in the water.  I then instructed the operator of houseboat A13 to go inside of Navajo Canyon to seek protection from the winds.  Once inside of the canyon I was able to approach the vessel and Ranger boarded the houseboat to gather information from the operator.  Ranger interviewed subjects who stated that they were towing their personal vessel down lake from Warm Creek Bay when the winds picked up and began to porpoise the bow of the vessel into the water.  They attempted to pull the boat in near the rear of the houseboat to start bailing it out, but were unable to as water began to sink the vessel from the bow, eventually capsizing it.  At that time they cut the boat free and it floated to its position where I found it at the mouth of Navajo Canyon.  They called for assistance on marine band at that time.  I photographed the vessel capsized at that location.
  I requested Aramark respond to remove the capsized vessel from the water.  At approximately 1700 hours they arrived on scene and began the removal process.  I observed as the recovery crew towed the vessel from the rock wall out into the main channel of the lake and to a nearby shore in order to right the vessel.  Once righted they towed the vessel to the Wahweap fuel dock.  On 06/18/2014 I found the vessel at the Wahweap fuel dock and photographed the damage to it.  There was significant damage to the starboard side fiberglass from hitting the rocks.  All windshield glass was damaged or missing.  The engine sustained total submerged water damage.  The ski tower appeared to be bent at an angle, and all items on the vessel sustained total submerged water damage.
  Cause:
  The cause of the capsizing was significant wind event that day coupled with the inexperience of the operator and passengers to realize their vessel was in danger.  Winds that day were 13-22mph, with gusts up to 44mph.
  
  Damage:
  Estimated to be between $10,000 and totalled.
