On August 10, 2013 at approximately 6:10pm boat bearing HIN number BUJD64TGB505 (Vessel1) capsize on Canyon Lake in Comal County while being towed in by an unidentified vessel 2.  Vessel 1 was being towed to Fort Sam Marina (Joint Base) because of engine failure.  One passenger on vessel 1 was sitting in the bow of vessel 1 when vessel 1 was being towed, passenger was also the person who tied tow rope to vessel 1 from vessel 2 other passengers in vessel 1 were sitting in the middle of boat. While vessel 1 was being towed, a storm blew in causing high winds and large waves.  Passenger was the only one sitting at bow of vessel1 until the second wave of water went into vessel 1 the party of five were all thrown to the front of the boat causing more water to enter into vessel 1. Immediately all 5 passengers of vessel 1 went to the back of the boat. 
Vessel 1 started taking on a lot of water causing vessel 1 to start sinking in the stern of the boat.  The five passenger immediately jumped out of vessel 1 and into the lake, all five passengers were wearing a PFD.  All five  passengers of vessel 1 were picked up by vessel 2. After all passengers got out of vessel 1, Vessel 1 capsize due to the amount of water inside the boat. 

When Game Warden arrived on scene 3 passengers were put on the Game Wardens' boat. Game Warden advised vessel 2 to cut the tow rope that was still attached to vessel1  that was capsized and Fort Sam Marina was notified to come out to retrieve their boat. All five passenger were taken to Fort Sam Marina with no injuries. 

Operator1 claimed to be the operator of vessel 1. Operator1 stated to the Game Warden, she called Fort Sam Marina prior to the storm twice because vessel 1 had very little power when she put vessel 1 in gear. Because of the heavy boat traffic on Canyon Lake at the time operator1thought she was slowly moving. 
It was latter identified the aluminum blades on the propeller were sheered off vessel 1 prior to being towed by vessel 2.
