From Firehouse.com:

The Chicago Fire Department has taken delivery of a Metal Shark Boats 38 Defiant NXT fire boat. The all-weather boat is equipped and powered by triple 350-hp Mercury Verado outboard motors.

Key features include SHOXS shock-mitigating seating, full Raymarine Axiom navigation suite, FLIR 400 XR thermal imaging system, and Metal Shark’s exclusive new hinged dive door. The vessel’s bow monitor and rear discharge are fed by a 1,000-GPM Darley fire pump driven by a dedicated Kodiak 4.3L V6 engine.
