RedactedNarrative: At about 1715 hours (MST), I was dispatched to a report of a vessel in distress in the area just outside the Dangling Rope Marina breakwater.  Dispatch told me that the vessel had run aground and was taking on water.  I arrived on scene at about 1720 hours, accompanied by a NPS interpretation ranger.  I observed 10 passengers, including a young female, approximately 2-3 years of age.  The vessel was drifting with the wind, on the leeward side of a rocky island located about 1-4 mile west of the marina canyon mouth.
  
  Once side tied to the vessel, the captain told me he had struck the rock island as they made their way downlake.  He said his bilge pump was keeping up with the water flowing into the boat.  There were no injuries.  He and I agreed the first priority was to take most of the 10 passengers off the vessel.
  
  Subject told me that he saw the one hazard buoy placed over the island, but not that portion of the island that extended from the buoy location toward dry land/shore.  He said the impact was very light, whereupon the engine shut off and the vessel began to take on water.
  
  I had noted on arriving at the marina that afternoon that a second hazard buoy, which had been located on the island hazard near where subject ran aground, had broken loose and was floating at the shore near the marina breakwater.  I re-positioned the buoy at the island the following morning in a temporary manner and advised Glen Canyon Maintenance the buoy needed to be re-anchored.
  
  A salvage crew arrived at the marina the next day to refloat and remove the vessel.
