Hoverflight 90 represents A High Profit Business opportunity for
passenger ferry operators requiring High Speed Passenger Transport over
adverse sea state at cruise speed of 75 knots.
In the Middle East Gulf Region, Maldives Islands, Asian Islands, Caribbean
Islands have many resorts that require travel over rough seas of 70 Nautical
miles. Their customers travel at an average speed of 25 knots at a
three hour travel time, encountering adverse monsoon seas for some
months of the year. Sea sickness is a result and customer often
never return. Hoverflight travels over the sea tat 75 knots 5 to 10
meters over the sea. As there are no updrafts or downdrafts, (as with
sea planes using this method of travel in the 1940's) there is no motion
sickness. Only a smooth ride where the food and champagne never
spill. Passengers return again and again to their favourite
Maldives Profitability Example
In the Maldives, an air ticket in a six passenger
aircraft can cost up to $120.00 USD per hour. They have over 200 resorts
on individual islands. The old current seaplanes cannot deliver
the 1.5 million visitors per year. Seaplanes do not land at night as it
is difficult to determine the drift to port or starboard. Landing
speeds are normally 90 Knots. Hoverflight has a hovercraft skirt that
allows the craft to land with a heading 30 degrees of track. The slow landing
speed of 45 knots together with our skirt system allows the Hoverflight
to land in adverse seas impossible with a seaplanes today.
Passenger load on Hoverflight 90 is 90 passengers. Assume
passenger numbers average 75 throughout the year.
75 passengers x $120 = $9,000 Per flying hour.
10 flights per day gives revenue of $90,000 per
Revenue for 300 days per year is $27,000,000 per
Cost of operations is about 25% of the
This increases business to the resorts adding revenue
to each individual business.

Aviation Engineering Software
following Pictures are from our Aviation Engineering Software used for
Design and Flight Testing of Hoverflight 90.
The Hoverflight is designed in this software similar to most CAD
software such as AutoCAD or Solid Works and then flown via this programme.
Most aircraft manufactures use
this or similar programmes for all new aircraft. When the
Hoverflight or aircraft is built exactly in accordance to the design in
the software, the proven accuracy rate is more than 97.5% when compared
to the actual flying performance of the finished aircraft. This software proves the craft is straightforward to fly with
minimal training to experienced sea captains with aviation experience.
Our Wing in Ground Effect craft have also been compared to many
seaplanes of similar type such as the Do-X of Germany, the American Catalina,
(the world most mass produced seaplane) and many others.
All construction is of marine materials for salt water open ocean
travel surveyed to International Marine Organization Regulations by
international class societies.
These craft standard retail price is a low $6,500,000 Australian
dollars for our standard passenger ferry. Luxury, Coastal Parol,
Customs and Military Hoverflights will .at the same price plus any additional
work to ensure the Hoverflight will meet mission requirements.
we are manufactures, not bankers, we can only accept a deposit
with progress payments throughout the building process. The final 10%
payment will be on delivery of the Hoverflight 90 before it leaves
We are interested in becoming Joint Venture partners with Cashed Up
Clients who operate in the fare paying passenger market. The
profits are far higher than we could ever hope to make from
manufacturing these craft. We can provide captains, maintenance people,
and all other operational staff. Our staff will ensure your
Hoverflight is flown safely, well maintained and the passengers
will be well looked after with on board movies, food, drinks in a safe air-conditioned
environment. Customers who partner with the manufacture are
assured every area of operations will be professionally managed as it
will be in our best interests to do so. It is highly likely profitability
will be greater under a Joint Venture Arrangement than a solo operation.
Wanted for Franchise Operations.
who require a huge return on their investments on an ongoing basis are encouraged
to meet with our team. We would like to meet with professional
investors and mangers to spread Australian Hovercraft through-out the
world. We are considering and operation very similar to fast food chains
such as McDonalds Restaurant or a BP petrol station. We set up a
profitable operation then sell this operation to individual operators.
Like all Franchises the owners of the franchise will have to comply to
the franchise agreement that ensures clean toilets, safe food, uniforms
on all staff, electronic accounting records, operations only within well
maintained craft to the franchise agreement and other normal
requirements. The history of Franchise owners is far better profitability
then owner operators and the business are normally long term and gain
considerable profits when they sell their franchise before

Modular Power Units.
One MAN 1300 HP radiator cooled
diesel is preferred for reliability and low weight for each modular
power unit. There are two
power units. The engine,
centrifugal lift fan and seven blade Pitch in Motion propeller (forward
& reverse thrust in a composite duct to increase thrust efficiency
and eliminate sound ) are installed in each interchangeable
modular power unit. An
engine speed of 2100 Rpm gives a propeller speed of 700 Rpm and
centrifugal lift fan speed of 1,200 Rpm. Steel plastic covered mesh
prevents passengers or cargo from contacting propeller blades. All
modular power units are interchangeable with other craft to eliminate
controls, throttle, rudder via a steering wheel, and an electric
hydraulic control lever for forward and reverse propeller pitch.
Engine RPM dictates the volume of air pumped under the craft
creating the desired air gap and propeller pitch dictates the desired
forward speed. Engine
instrumentation, running lights, air conditioning, safety equipment and
anchors are standard on all craft.
Flying controls for Hoverflight are identical to conventional
aircraft being three axis elevators, (main wing) rudders (behind
propeller) and elevators (on top of propeller duct) as shown. In
addition the main wing angle of attack is varied to a greater angle of
attack for take off and landing at 40 knots to almost neutral for
cruising at 70-75 knots on 65% power. The hull and passengers remain
horizontal at all stages of flight.
hull is manufactured from marine grade aluminium plate, 1.2m wide, 13.0m
long 4mm thick underneath
the hull and 3mm on sides and deck.
This plate is bent longitudinally. The bent plate is then welded
longitudinally by an automatic welding
The four bulkheads are then welded into place forming three
watertight compartments, comprising the anchor storage, cabin and engine
The bottom and sides of the hull is bonded to foam flotation, the
shape being cut by a computer controlled wire cutter.
This provides emergency flotation outstanding heat insulation and

skirt is made of hyperon nylon neoprene and is a special variable
pressurised chamber type designed and manufactured by Australian
Hovercraft Pty Ltd. This
skirt was designed to operate in rough sea conditions with a design life
of 4,000 hours. Our
current craft has shown no skirt wear over a two year testing program
with no skirt maintenance. This
design allows the hovercraft to travel high speeds in very short seas.

craft operate on/over water then dock at any jetty, mud flats, or waters
edge to offload passengers or cargo. Shore to ship or ship to ship
transfers are best done at a speed of 5 knots where in rough seas our
hovercraft skirt will press against the ships hull allowing safe
passenger and cargo transfers. The skirt is a excellent buffer and hull
protector for both vessels. Operations over sand or rocks are not
recommended due to possibility of sending sand into bystanders' eyes or
into the propeller. Passengers
on our hovercraft
demand a maximum speed of 5 knots over reef so they can stand outside
the cabin to view reef, coral, sea grass, fish and other marine
creatures. Water skiing in
deep water is a must for tourism providing great fun for skiers and
onlookers alike. All Passengers stand on the port or starboard side of
our craft with little or no listing. Fuel consumption figures per
engine manufactures specifications at 65 to 70% of full power. Engine
life with excellent maintenance is between 8,000 and 18,000 hours. These
figures change to various operational factors such as short trips, high
engine load with many cold starts (8,000 hours), long trips or
continuous operations where the engine is always hot with constant power
settings (18,000 hours). Quality
servicing eliminates down time and extends engine and component life to
reduce operational costs.
