RAnger 2650 Class fireboat from Robert Allan Ltd. for City of Baltimore

September 6, 2007


In July, 2007, the new RAnger 2650 Class fireboat, John R. Frazier, was delivered to the City of Baltimore Fire Department by the builder, Hike Metal Products of Wheatley, Ontario. The vessel was designed by Robert Allan Ltd. of Vancouver, BC, who worked with Hike to win this internationally bid design and build contract. Evan Gatehouse, P. Eng. was the Design Project Manager for Robert Allan Ltd.

The new fast response fireboat is designed to specifically address the fire fighting and rescue needs of the local port area. Consequently the fireboat has both water depth and air-draft constraints.


The new fireboat has the following particulars:


Length Overall
Beam, Moulded
Depth, Moulded
Maximum Draft (overall)
– 87′-0″ (26.50 metres)
– 22′-0″ ( 6.70 metres)
– 12′-4″ ( 3.76 metres)
– 7′-3″ ( 2.21 metres)


The tank capacities are as follows:

Potable Water

– 2,500 US Gallons (9,450 Litres)
– 250 US Gallons ( 945 Litres)
– 1,000 US Gallons (3,850 Litres)


The fireboat was designed for a response speed of 16 knots. On trials, the vessels achieved a full load speed of 17 knots.

The installed propulsion power is 2 x 1,650 BHP (2 x 1230 kW) from two CAT 3512B main engines. Propellers are fixed-pitch, driven through a pair of ZF model 4650 reverse-reduction gears with a 3.04:1 reduction ratio.

Interior noise was well controlled, with maximum levels of 72 dBA recorded in pilothouse and crew quarters at full power.


The Fire-fighting equipment for the RAnger 2650 Class comprises the following:


  • Fire pumps
    • 2 x 3,500 GPM (795 m³/hr), each driven by an independent CAT C-18 diesel engine
  • Fire monitors:
    • 1 x 5,000 gpm (1,135 m³/hr) – remote controlled
    • 1 x 2,500 gpm (568 m³/hr) – remote controlled
    • 2 x 2,500 gpm (2 x 568 m³/hr) – manual controls
