RedactedNarrative: The Operator of Vessel 1 was surveying ice damage on a horse farm by boat on a flooding river when Vessel 1 collided with a large chunk of ice, sending Vessel 1 into a flooded show ring (which was also filled with ice).  The Operator was able to grab onto the show ring fence and push Vessel 1 back out of the ring.  Vessel 1 then collided with another chuck of ice, pushing Vessel 1 backwards toward a tree line.  Vessel 1 became pinned against a tree and began to swamp.  The Operator of Vessel 1 then left Vessel 1 and climbed a tree.  Vessel 1 broke free of the tree following the Operator's departure and was pushed into the flood waters and never recovered.  The Operator of Vessel 1 was later rescued by a local fire department.
