FIB - Flying Inflatable Boat,
What's new since the 2001 version .
The basic fact is that the boat used in the Fib 2001 is designed from scratch
to be used as a flying machine. The boat has now in common with a traditional
rigid hull inflatable boat (RIB) only the external look and some of the
material. This allows the use of a new wing specially designed and with advanced
performances. Here below the main differences.
The Lomac boat
All this improvements make the Fib 2001 boat completely different from a
standard inflatable because it's specifically designed for the particular use we
make of it and it is the fruit of the experience we gained in 13 years of
production and flying of this particular ultralight. The weight of the Fib 2001
boat is now only 58 Kg (127 Lb) and this includes the paddles, rudder, air pump
and all the stainless steel hardware fixed on it !!
- With the help of Lomac's designers and after many tests, we increased
the volumes on the bow to compensate the trust of the propeller that,
contrary of what happens in a traditional boat, is high in the air instead
of underwater. This allows the bow under full trust to come out of the water
much quicker and the stern has not anymore the tendency to "slip"
laterally under the same conditions.
- We increased the V on the bow to improve the performances in choppy
- To help the planning, especially in completely flat water, a well-known
boat architect (Donno Des. ) designed for us some lateral steps in the stern
region and longitudinal ones in the bow. This breaks the "suction"
effect that is experienced in those conditions. The system is used in big
boats to help planning with low power. In our case we found out that it
corrects also the "torque" effect we experience when we give full
power in "plow" running and quickens a lot the transition to
"planning". To reach this result, and also to improve the
longitudinal stability, the boat is wider in the back. All this allows to
start from 0 speed to taking-off speed practically without using the rudder
and makes nearly impossible the 180 spins experienced sometime in particular
conditions or sloppy piloting.
- The deck has a new design to improve structural strength but with less
material and can be filled with water for improved stability in taxiing in
strong wind conditions.
- The resin used, instead of the traditional Polyester, is Vynilester
that has characteristics very near to the Epoxy resin. We have in this way a
stronger, more elastic and lighter hull.
- The Hypalon used for the inflatable part is now much lighter than the
standard one but with equal strength and durability.
The performance of the hull allowed us to mount standard on Fib 2001 a
completely new designed wing that is 2.5 Sqm. smaller than the original one.
The wing has a different shape of the "roach" , variations in the
batten profile to widen the speed ranges and has more tension in the leading
edge and in all the wing surface. We maintained the same span of the 21Sqm in
this way we have now a bigger :aspect ratio". We reach in this way a better
handling in the air (practically similar to that of a normal land trike), a more
safe handling in taxing with strong wind joined with slightly improved maximum
speed but maintaining the low stall speed.
The wing is studied for the use in sea environments and has all stainless steel
bolts, some sealed parts and tube-to-tube junctions made with special grease for
This wing can be used only on the new version of the Fib and as a training wing
in trikes and in trikes dedicated to hang-glider towing.
Just to give an idea of the performance of the FIB 2001 we succeeded in
taking -off it with pilot and passenger, Rotax 503 engine (48hp)flat surface and
wind in the back of approx 4knots! Something impossible with the old Fib 582
(64hp) and surely for all other sea-ultralights in the market.
