Unit 1 travels upstream on Savannah River at night in an area with no artificial illumination and moonrise had yet to occur. 

Operator unit one noticed pilings immediately to his front. Operator unit 1 made a hard turn to starboard to evade the pilings, only to run aground on the bank at speed, striking a tree, ejecting himself forward through the windscreen and ejecting front port passenger and rear passenger into the river.

 Damage to the port bow hull is catastrophic with transom buried in the mud.
