VESSEL WAS TRAVELING UPRIVER ON PLANE WHEN IT STRUCK AN UNSEEN UNDERWATER OBSTRUCTION.  THE COLLISION OF THE LOWER UNIT WITH THE OBJECT DID A LITTLE DAMAGE TO THE PROPELLER, BUT ALSO LIFTED THE VESSEL SLIGHTLY IN THE WATER COLUMN, CAUSING THE VESSEL TO LOOSE TRACTION. WHILE LIFTED ON TOP OF THE OBSTRUCTION, THE VESSEL ROTATED, WHICH CAUSED THE VESSEL TO VEER SHARPLY ONCE IT SETTLED BACK DOWN IN THE WATER COLUMN. BEFORE THE OPERATOR COULD THROTTLE DOWN, THE VESSEL HAD VEERED TOWARD A LARGE ROCK AND COLLIDED WITH IT. THE COLLISION WITH THE ROCK CAUSED DAMAGE TO THE FIBERGLASS HULL ON THE UNDERSIDE OF THE FRONT OF THE VESSEL. ALCOHOL WAS NOT SUSPECTED IN THIS ACCIDENT AND A PFD WAS NOT BEING WORN OR USED. NO INJURIES WHERE SUSTAINED.
