A jet powered boat may be provided with a water monitor for fire fighting purposes. The conduit for the monitor is connected to an opening through the bottom of the hull to draw water vertically from beneath the hull. Two motors are provided in the boat. One motor is configured to propel water through the monitor conduit to the water monitor. The other motor is configured to propel water through a propulsion jet at the rear of the boat. In one embodiment, a second propulsion jet is provided at the rear of the boat, connected to the conduit for the water monitor. A baffle at the intersection of the second propulsion jet and the monitor conduit may be operated to selectively direct water to either the monitor or the propulsion jet. In this embodiment, the two motors may be placed symmetrically on either side of the longitudinal centerline of the boat. In another embodiment, in which one motor exclusively supplies water to the water monitor (without the second propulsion jet), the two motors may be placed fore and aft along the centerline of the boat. The hull of the jet powered boat is shaped with progressively shallower segments of the hull bottom spaced farther from the hull centerline to provide the directional stability of a "V" shape near the centerline, with a relatively flat shape near the sides of the hull for lateral stability. Debris screens may selectively be placed in the water intake openings through the hull to block pump-damaging debris.
