Because most marinas and private docks in Sausalito, Calif., have limited or no access to hydrants and conventional fire apparatus has trouble negotiating the terrain around the water-front, Chief Charles Masten designed an attack pumper to handle the situation. The pumper has a 1-ton chassis with a pump, water tank, hose and ladders. For boat and dock fires, the attack pumper carries a Waterous Floto-Pump. The 48-pound floating pump operates without a suction hose and can discharge 140 gpm at 27 psi or 20 gpm at 105 psi.
Masten said his department has used the pump for boat fires where the only source of water was San Francisco Bay. When the attack pumper arrives, the chief explained, the shift commander takes a 30-pound ABC extinguisher and an ax and goes immediately to the fire. The driver drops the pump in the water and uses a 100-foot length of 1 1/2-inch lightweight hose with a 60-gpm nozzle.
