A few weeks ago they ran a jet boat from Youngstown NY all the way to the base of Niagara Falls which is uncharted waters and has never been done before. They do run jet boats from Niagara on the Lake to the Whirlpool which is about four miles from the falls. The jet boat was doing 35 knots but in the rough water was put back to 15 knots.
