RedactedNarrative: V1 was attempting to dock the vessel at the gas dock when he bumped the swim platform of the vessel while swinging the boat around. He then proceeded to pull in at a faster speed & turned around again, almost hitting another vessel that was docked.  The Operator then gave the vessel more throttle & swung the boat the other direction & hit V2 that was moored to the dock.  V1 then attempted to leave yet an employee of the Marina made contact & ushered V1 back to the dock.
