City of Seattle Fire Department Fireboat built by Dakota Creek

Two MTU 8v-400 M71 diesels drive ZF W4610 gears, turning 72-inch, four-blade propellers.  Each of these engines is rated to deliver 1550 hp at 2000 rpm.

The main feature of the Leschi is its system for combating CBRNE events.  The central function of this system is to protect the atmosphere in key areas of the vessel.  At the touch of a button, the vessel goes into CBRNE mode: an alarm sounds, lights flash, and the bridge, mobile command center and several other parts of the boat become Toxic Free Areas (TFA).  Doors are sealed, fans and filters kick in and pressure inside the TFA increases to two atmospheres.  The CBRNE system was custom-designed, engineered for Leschi by DCI.
