RedactedNarrative: People were talking and dancing on the back platforms and their weight was not distributed right.   The back was filling water in the air vents, which filled the bottom of the boat and adding weight.  Before everyone noticed what was happening, it was too late.  The back of the boat went into the water and we tried driving off,  but the engine was to far under water to start.  So the boat sunk.
