RedactedNarrative: Inland marine has security cameras that recorded the entire encounter.  On july 2nd, i viewed the footage at the marina.  The footage shows clearly that vessel1 was tied off to the dock during the storm.  It then shows another white vessel approach the gas dock's.  The vessel had a readable indiana registration number of 6382dm.  This vessel pulled up to the gas docks and tied off.  All of the occupants exited the boat and stood under the awning during the storm.  After a while, one white male boarded the vessel and pushed off from the dock.  The operator was the only occupant aboard the vessel and appeared to be skinny with tattoos.  The operator maneuvered the boat away from the dock then engaged the motors rapidly causing his boat to lurch forward towards docked vessel1.  The bow of the boat then struck the rear portion of the starboard side of vessel1 pushing it violently against the dock.  The vessel then floated in the water until owner1 exited his cabin and confronted the operator.  The operator appeared to speak with owner1 before speeding off.
