RedactedNarrative: Vessel #2 (a houseboat) was towing vessel #1 (a ski boat) in the vicinity of buoy 56 on Lake Powell when adverse water conditions were encountered. Vessel #1 took waves over its bow, swamped, and quickly sunk beneath the water surface. 
  
  Its towline was subsequently detached from vessel #2. Vessel #1 remained suspended in the water column at about 20 feet by a combination of its inherent buoyancy and that afforded by a large inner tube (used to tow passengers for recreation), which was tied to vessel #1 with a ski rope, approximately 20 feet in length. The inner tube was the only item visible above the water. 
  
  Operator2 motored vessel #2 to Dangling Rope Marina where he reported the accident. I transported Operator2 to the area of buoy 56 and located vessel #1. The vessel, with tube still attached, had drifted toward the east northeast until contacting a canyon wall near buoy 56, and lay in approximately 15 feet of water. Operator2 attached the vessel to a large rock on the shore with a line and it was subsequently salvaged and removed from the lake. We recovered various flotsam from the sinking and transported it to vessel #2.
