RedactedNarrative: Operator of vessel #1 was under power east bound through the channel when she observed vessel #2 operating at an excessive speed west bound through channel. This river is a head speed only. Operator of vessel #2 did not give a signal to indicate he was entering the channel either. He did not make an attempt to get away from vessel #1 a smaller vessel and when they passed each other they collided causing property damage. Operator of vessel #1 yelled over to vessel #2 notifying that he struck her vessel and needed to stop to get her vessel free as she was being dragged backwards through the channel by his vessel. He refused to slow down and stop his vessel causing both vessel to head outside the channel. She was then able to get her vessel free and made multiple attempts to have the captain stop so they could assess damage and exchange information, he still refused and power up river. It is unknown if vessel #2 had any damage as he is moored out of state and refused to return phone calls from the officer.
