RedactedNarrative: Vessel 1 was travelling on plane and said he must have just missed seeing the last navigational buoy before the Prescott Slow No Wake on the Mississippi River and was just outside of it and struck a wing dam with the vessel, causing a large hold in the hull and damage to lower units.  Vessel was returned to a dock in Prescott where the marine, fire department and law enforcement agency assisted with pumping the vessel out and loading on a trailer at the launch.
