Woronora Bushfire Brigade is a totally marine based unit, with
the only vehicle being a personnel carrier. We have evolved a boat design
philosophy
over nearly 30 years of practical experience fighting
bushfires
from the water.
The general principles we use when designing boats are :-
- Aluminium is stronger and lighter than fibre glass (tupperware!), and
doesn't burn.
- Have as little superstructure as possible (or removable)
to simplify getting under road
bridges, and to allow easier access through mangroves.
boat plan.
- A split bow rail will allow boat crews and equipment to be easily
set down on shore.
- Twin motors are essential for reliability. We prefer outboard motors
because they have a very good power to weight ratio, are easy to service
and don't take up valuable space in the boat. They have the highest fuel
consumption, but we don't go on extended or frequent voyages (the new
Honda four-stroke outboards look promising, with 50 percent reduction in
fuel consumption, higher reliability and available in sizes up
to 130 Hp). In a open
plan boat, petrol in not a safety issue and the boat can easily pass
survey requirements.
- A quick response it vital, since most fires will be burning up hills
and difficult to catch. All our boats can do better than 30 knots with
all equipment and a full crew.
- Avoid sharkcat or broadbill boats unless to have deep water, or have to
negotiate heavy swells. They draw a substantial amount of water and strand
easily in small rivers and creeks.
- Flat bottom boats may seem attractive, but perform poorly in anything other
that glassy water; and have marginal advantages for shallow water. On the
positive side, as a tender for larger boats, they can be an advantage
because of their stability (not in bad weather) and ease of access.
- If you paint your boat, leave the bottom bare. It will get scratched
or knocked easily and will look tacky after only one fire season.
- Use a large capacity pump of at least 1600 litres per minute; water supply
is no problem.
- Have a large hose complement of 38mm and 65mm hose (at least 2500 feet).
The use of 25mm hose is a total waste of time. Most of the hose lays will be
up hills, and hose friction and head losses become substantial.
- An easy handled portable pump in a rectangular frame is essential.
It will be used mainly for relay pumping, and crews will have to lug
them up hills, over rocks and other obstructions.
- Have a good selection of branches including fog for structure fires,
foam for boat fires,
and some of the older straight or AWG's to deal with low pressures on long
hose lines.
- Use a CQR plough anchor with plenty of chain for good ground
holding. If you have rocky bottoms, either rig the chain to the head
and have a weak link on the shank or use a reef hook.
The Brigade has three fire boats,
named after prominent members of the Sutherland
organisation. We have two large boats for direct fire fighting, and a small
one for crew transport, mop ups and chasing spot fires. A bare minimum crew of
four is usually required, with six or eight preferred (remember the hills!)
Woronora Fireboat Len Carter
(1893)
This boat was built by Yamba Welding in late 1993 and
is the largest and most heavily constructed boat we have. It has ample
space for the storage of equipment and hoses. It is our first
response boat (tides permitting) and its normal equipment list
includes :-
- Godiva GP1600 main fire pump connected to a header tank on the foredeck
with two 38mm and one 65mm deliveries, along with a 65mm water monitor used to
fight boat fires or attack fires on the shore. See
monitor.
- A portable fire pump in a sturdy frame.
- Approximately 400 feet of 65mm hose.
- Approximately 2100 feet of 38mm hose.
- Two Sabre Centurion breathing apparatus with DSU's (distress
signal units),
intrinsicly safe torches, spare cylinders and a BACO board.
- Communication equipment including fixed GRN (trunked radio), VHF and Marine
radios, cellular phones and hand held fire ground radios.
- Safety equipment such as First Aid kits, Oxyviva and fire blankets.
- A large selection of Elkhart, Hoenig, AWG and straight branches.
- A foam branch and four drums of AFFF.
- Forced entry tools for structure fire fighting.
- A selection of Y pieces and adaptors.
- Hand tools such as brush hooks, McLeod tools, bush saws and shovels.
- A chain saw, axe, wedges and protective equipment.
- Drip torches and spare fuel, two-stroke and chain oil.
- Drinking water and a ration box.
- Marine equipment such as spare anchors, boat fenders, marker buoys,
boat hook, life jackets and a life ring.
Woronora Fireboat Ray Watchorn II
(1892)
This is a 7.5 metre boat that was custom designed Bill Bollard, rated 2C for limited
offshore use. It has a similar equipment manifest to the Len Carter, with the following features:-
- Cabin with lowerable targa mounting for radio antennas, beacons etc
- Planing hull with moderate deadrise, but with a bow ramp that can be
lowered to allow easy access for fire crews
- Partly below deck fire pump using a Yanmar 59Hp turbocharged marine
diesel motor with wet exhaust, coupled to a Hale CBP3 pump.
- A choice of seachest or suction line for water supply to the pump
- Foam proportioning system
- Twin Honda 130Hp 4-stroke outboard motors, with 250l of fuel
- GPS Chart plotter
- Marine VHF and 27MHz radios in addition to the GRN radio system
- Liferaft and EPIRB
Woronora Fireboat Max Giles
(1891)
The Max Giles is the water equivalent of a personnel carrier.
It is a modified flat bottom boat build by Yamba Welding and is
used to ferry crews and equipment to fires. It does have some fire
fighting capability by having hand tools, a small portable pump,
600 feet of 38mm hose and some Y pieces and branches.
See Fighting fires using boats.
Personnel Carrier
(1831)
A four wheel drive Land Rover Defender Extreme (110) is used to tow the smaller
boats, crew transport and general brigade activities. The Defender has excellent
off road capabilities and the aluminium body work means it survives the
salt water environment without rusting to bits!
