I'm curious as to how a fireboat holds position when a water cannon is throwing a massive stream of water a hundred feet or more onto a fire. That's a rather large force trying to move the boat directly away from the fire. Presumably the boat's engines can be used to counter that force, but precise control would be difficult, particularly as the cannon's operator moves the water stream laterally. Does anyone here know?
A related question, likely not practical in nature, would be whether the trip from dock to fire could be shortened by aiming the water cannon to the rear (and over the crew!) and pumping water full blast.
