MAD-81 is new concept of hovercrafts. MAD-81 hovercraft is simplicity of old 2 person MAD hovercraft, combined with BUFO hovercraft high performance that is simply beyond compare to any other leisure hovercraft or amphibian rescue boat. MAD-81 hovercraft is designed to be the best performance craft in class of 3-4 person hovercrafts, designed for highest power to weight to platform size ratio, designed for fastest hump speed time in all conditions with maximum payload of 4 persons. Because of excellent characteristics, MAD-81 is a multi purpuse hovercraft, that can be used for rental business, transport of different payloads, people, for search and rescue operations, racing, hunting, fishing, water rescue, ice rescue .... If you seek for best performance amphibian boat, MAD-81 series hovercraft is right machine for you.
Fully operatable on land, water, snow and ice. Also hovers on any kind of floods, flash floods, swift and shallow waters... Fast and safe to travel from one point to another where boats can not go, no matter if there is a land or water snow or ice. When off cushion, can be used as normal boat!

Other Facts about MAD-81 hovercraft
MAD-81 hovercraft has inbuilt buoyancy in ratio 1 liter of closed cell floating material, that does not absorb water goes on 1 kg of hovercraft weight.
With simple words – complete weight of craft is about 200 kg, and volume of inbuilt floating material is 200 liters, the result is – UNSINKABLE hovercraft.

MAD-81 buoyancy characteristics
MAD-81 hovercraft buoyancy is positioned exactly where the most needed, at the rescue boat bottom and sides.
-
50 liter is placed on the bottom, what makes complete bottom in sandwich (bottom is extremely strong)
-
100 liters is placed at hovercraft sides, to most critical points, what makes hovercraft very stabile on water on water stop, so allows you to work on hovercraft sides, and hovercraft will not tilt
-
50 liters of built in hull buoyancy is installed inside of hull, so in case complete cockpit is flooded by water, hovercraft still stays on top of water surface
-
MAD-81 hump speed time 3-5 seconds in all conditions
|
All hovercrafts face a dificult hump situation after a water stop, most of the hovercrafts are able to beat a hump with one person but it takes some time to do so, when more people is on board story is ended – hovercrafts can not come out from the water. We solved this problem, and our hovercrafts have no problems beating the hump no matter the payload. When we say hovercraft is for 3 person it means it must beat a hump with 3 person same as with one… and it must work in all condtions with one or three person onboard. MAD-81 hovercraft has NO PROBLEMS beating HUMP phenomenon no matter if there is one, two or three person on board, MAD-81 is also designed for fastest hump speed time possible under all kinds of conditions, so no matter what payload you carry, you are out of water in 3-5 second time! |

MAD-81 thrust duct information
MAD-81 is powered by BUFO Hovercraft HIGH efficiency 900mm duct. BUFO thrust duct system proved its performance on World Hovercraft Championship 2008 and Europe Hovercraft Championship racing 2009, where the duct and hovercraft performance was tested in extreme conditions against world’s meanest hovercraft racing machines and toughest situations possible for hovercraft operation. This high performance duct is now the thrust power of new MAD-81 amphibian rescue boat. High efficiency duct means that our models have MORE thrust power with 52 or 65 HP motors than some other hovercrafts with 100 HP motors and because complete MAD-81 is lighter it simply works better. Hovercraft power cannot be measured with motor horse powers, but in relation of thrust power (outflow force) and complete weight of the hovercraft. Only the right ratio of thrust power and weight gives you what we call HIGH PERFORMANCE HOVERCRAFT. To get the idea of what we call performance see this video on youtube 65 hp strong hovercraft against 52 HP Bufo. 65 hp should be stronger, but you can see the difference and also hear, because our models run very quietly.

MAD-81 rudder control information
 MAD-81
has special designed symmetric aerodynamic shaped rudders,
available in
combination of 2 rudders or 4 rudders for better
maneuverability. For better response, rudders are positioned
behind the duct, so they catch complete airflow from thrust duct
and direct it to left or right under about 60 degree angle, what
makes incredibly responsive hovercraft when steering left right. Hovercraft can without problem turn on spot in a second,
without going forward. Shape of rudders is symmetric aerodynamic
foil that makes minimum turbulence and not effect on thrust
power of hovercraft, and keep noise level down as much as
possible. |

MAD-81 Fuel Tank
|
MAD-81 is equipped with 30 liter fuel storage tank of our own design, which is fabricated from polyethylene. Fuel tank is fabricated by roto-moulding technology under all necessary standards for fuel storage tanks. Hovercraft fuel tank has 4 separate chambers, what limits the movement of fuel during the ride to minimum, so fuel bumping does not affect the hovercraft performance and stability. Fuel tank is positioned under the seat console, right to the center of hovercraft weight, so no matter if fuel tank is full or empty, hovercraft keeps same performance. With our fuel tank hovercraft NEVER runs out of fuel when minimu level of fuel is inside of tank, no matter if you drive uphill, or downhill with minimum level of fuel in tank. Full fuel tank or empty fuel tank does not effect the hovercraft performance, balance and stability. |
 BOAT fuel tanks are NOT GOOD for HOVERCRAFTS! We are the only manufacturer who use special fuel tanks designed for high performance hovercrafts! |
