RedactedNarrative: On September 12, 2018 at approximately 1439 hours, while on duty as a Law Enforcement Officer within Glen Canyon Ntl. Recreation Area, I received a report from dispatch of a sinking vessel near buoy 21. Dispatch informed me that the vessel was a wakeboarding boat being towed by a rental houseboat. Dispatch informed me that there was no one on board the wakeboard boat and that it was still attached to the houseboat. At approx. 1500 hours, I departed from Wahweap on a patrol vessel and located Aramark rental houseboat J4 near Padre Butte at buoy 22A at 1530 hours. 
  
  I observed that the wakeboard vessel was capsized with only part of the stern sticking out of the water. The vessel was still attached to rental houseboat J4.
  
  V1 subject told me that at approximately 2:35pm they were underway with their 2009 Malibu LXi ski boat in tow behind the houseboat. Their towline was affixed to the bow eye of the vessel with the other end affixed to the houseboat stern. V1 subject told me something to the effect of, they were near buoy 21 when they observed a wave come over the bow of their ski boat. V1 subject stated they attempted to try and keep the ski boat from taking more water by lifting up on the towline, however, their attempts were unsuccessful. V1 subject and the ski boat continued to take water and within 3 minutes it capsized, still attached to their rental houseboat. V1 subject was the operator of the houseboat while the ski boat was in tow. V1 subject hailed National Park Service dispatch on Marine Band 16 and was instructed by NPS to keep the towline attached as long as it did not danger their houseboat.
  
  V1 subject remained stationary in the main channel. Their houseboat and ski boat were blown northwest from Buoy 21 to Padre Butte Buoy 22A. Winds were sustained at approximately 15mph with gusts to 24mph according to National Weather Service data (see attached). When I arrived on scene, they were within approximately 100 yards of the rocky shoreline of Padre Butte. I side-tied towed from the houseboats port side while Subject2 pushed the houseboat with his vessel on the starboard side. Subject2 and I assisted the houseboat with capsized ski boat in tow across the main channel, west of Padre Butte. There we secured the capsized ski boat with a Danforth anchor to a sandy beach. Executive Services and Antelope Yacht Services were contacted, both of whom stated they would not be able to recover the ski boat until the next day (09/13/2018). With only part of the vessel, mostly the stern portion of the hull, sticking out of the water V1 subject and I secured an orange flag to the rudder to warn other boaters of the hazard. 
  
  items lost from the ski boat included: a "Sky ski, water skis, ski ropes, vests, barefoot and wet suits were on the boat, along with a brand new prop that we purchased just before our annual trip this year". The vessel was recovered the following day by Executive Services. According to NADA guides the 2009 Malibu LXi base model had a suggested list price of $47,300. Current average retail value is $33,820.
