Hovercraft : HoverFlyer-580
The HoverFlyer is a fully amphibious hovercraft that has
been well proven
and manufactured since 1989. It has provided many thousands of
of enjoyment and income for commercial owners carrying many thousands
joyriders. HoverFlyer has also proven itself in many diverse
such as seismic surveying, aquaculture, weedspraying, flood rescue,
feeding, oil rig support to mention a few. Private owners too are
the benefits of the HoverFlyer with uses as diverse as yacht tender to
accessing fishing, diving, holiday house access and hunting.

|Hull and Superstructure
The hull is molded from fiber reinforced resin and PVC
vacuum formed into female molds. Bi-axial fiberglass
are used in the plastic skins. This method of construction is
while retaining excellent strength and stiffness. Thermal and sound
properties are excellent for this construction system. All laminating
conducted with active quality control procedures to ensure the highest
quality. The hull construction complies with or exceeds the Australian
U.S.L. requirements. The hull is built in two parts and bonded together
with sealed buoyancy compartments for maximum safety. Seat bases
are molded directly into the hull and provide dry storage spaces
A three-point rubber cushioned landing pad system is fitted under the
for operation off hard surfaces. A poly carbonate
is fitted around the front of the cockpit.
The thrust engine is a Subaru liquid cooled four
opposed four stroke with electric starting; no alternator; internal oil
reservoir; gear driven oil circulation pump; replaceable external oil
cartridge; stainless steel exhaust system; remote air filter
Normal running speed is 900 to 4200 R.P.M. The engine
is mounted directly to the transmission housing thereby assuring
alignment with the other transmission components.
The engine coolant circulates through a radiator mounted to the port
side of the engine compartment, the engine oil is cooled by an oil
mounted to the port side also. Sensors are fitted to detect oil
water temperature and cylinder head over temperature, and are connected
to a large flashing light on the dashboard.
The power from the thrust engine is transmitted from a
mounted directly to the crankshaft, via a toothed H.T.D. pattern belt,
to a toothed pulley mounted directly to the propeller shaft
The clutch on the propeller shaft is of the pre-set torque limiting
to guard against transmission system over-torque. The propeller
is supported on two self aligning sealed ball bearing units within the
fabricated aluminum transmission housing. The complete engine and
assembly is unitized and mounted to the hull via rubber vibration
The propeller is bolted directly to the rear of the propeller
The propeller blades are machined from select laminated timbers and
with abrasion resistant coatings and replaceable poly carbonate

driven oil circulation pump; replaceable external oil filter cartridge;
stainless steel exhaust system; remote air filter assembly.
running speed is 2700 to 3200 R.P.M.
Air is drawn in through the vents in the bonnet and expelled directly
downwards into the skirt bag. The bonnet provides safety
sound absorption and an attractive appearance. The lift fan is a
single stage, vertical downwards, axial flow type, mounted directly to
the engine crankshaft.
The controls are easily managed with a hydraulic helm
pump and hand-wheel
for steering. They are linked to aerodynamic rudders mounted
the thrust duct, and use a foot-operated throttle for thrust and a
hand throttle for lift. Full engine instrumentation is available.
The skirt is a fully pressurized tapered bag and finger
bag pressure is higher than the cushion pressure and is regulated by
orifices in the bag inner membrane. The fingers are bolted on
nylon fasteners and are easily changed without lifting the craft.
System voltage is nominally 12 volts DC. There is
a single battery
fitted with a double pole isolated switch. Circuits are protected
by mil spec re-settable circuit breakers. Both engines have
starting with a 15-amp alternator fitted to the lift engine. In the
of a flat battery, the lift engine may be rope started for battery
|Fuel System and Fire Safety
The fuel tanks are of approved welded aluminum
construction and pressure
tested. Fuel piping is copper and stainless braided neoprene for
elements. A CAV type conglomerator/filter unit provides filtration,
is easily accessible for inspection and water drainage. An electric
pump feeds both engines. A tank-mounted sender measures the fuel
and a gauge is fitted to the dashboard. In survey craft the fuel
tank compartment is sealed, lined with fire retardant surface and
ventilated. An electronic fume detector is mounted within the
with an audible and visible condition monitor on the dashboard.
Marine radio, 27Mhz or Marine VHF
Storage cover, short version clips around duct and top of windscreen.
Storage cover, complete version, covers complete deck to top of skirt.
