I was dispatched to a report of a boat against the dock and not operational at the Windy Hill boat ramp.  
  I arrived at the Badger boat launch ramp and observed a boat sitting sideways on the concrete wholly out of the water.  On the ramp were also the boat''s owners and their truck and boat trailer.  I observed the trailer''s sideboards were broken and two of the uprights were damaged being bent over.
  I contacted both two people and obtained statements from them.  Both stated the weather had become threatening and they had tried to load their boat onto their boat trailer.  They stated the waves were not bad when they started but the wind had suddenly come up with waves they estimated at over 3 feet when the boat was just starting onto the trailer.  The waves were coming into the boat from the stern and 10-20 degrees to port.  The boat was carried sideways by the wind and waves into the trailer causing several gouges and tears in the hull over the length of the port side.  The propeller was reduced to a hub when it hit the concrete still under power.  Operator was the operator of the boat while Subject had backed the trailer into the water.  After the damage and loss of the propeller Operator was able to get off the boat safely.  The large waves coming onto shore at the launch ramp pushed the boat up the concrete sideways where I observed it now out of the water upon my arrival.
  The boat had all required safety equipment on board.  It was subsequently refloated on the morning of the fifth by the Roosevelt Lake Marina operators and placed on its trailer.
  Initial estimates of fiberglass damage were in the six thousand dollar range with another five hundred dollars to repair the trailer.
  During the time period when the waves came up Roosevelt Lake experienced a high wind event from an outflow boundary of a thunderstorm which collapsed over the area of Tonto Basin.  The closest automated reporting station in Tonto Basin recorded winds at 24mph with gusts up to 37mph.  The winds from the boundary event at the lake were estimated at 50+mph.
