To take off this stack, a one meter long control bar with line reels was built.
|
The first tests were made with boards but the kite stacks
were so difficult to launch that they found water skis easier.
After a few months, they came to the conclusion that stacked kites were not the way to go,
and that a frame of inflated tubes was the answer.To make larger kites, they had to
return to Brittany and abandon the plan of sailing around the world tour, and so back to
Brittany they went.

First high speed sailing with a single inflated wing and skis. October
1984
|
They participated their first Brest Speed Sailing Week in
April, 1985, winning the Innovation Award, and participated two others in 1986 |
The goal was to get into an R & D and manufacturing arrangement with sailboard sail
manufacturers, but the time was not right. The sailboard market was at its peak and
everybody considered windsurfing as the ultimate sailing.
At that time, their kites were just prototypes. They couldn't go upwind with skis or
boards, so they worked for years on skis, boards, boats and kites, and dabbled in several
other ideas, looking for a market.

Dominique's ready!
Big foots ! September 1985

In 1985 and 86 they built their most
efficient wings, with a very high aspect ratio and completely double skinned. But they
were heavy, especially when wet. Worst of all, they were so unstable that just keeping the
kite flying required a great deal of effort.. They felt that their sport could
grow faster if the wing was more stable. |
Bruno demonstrates their system at La Torche in 1987
during the World Cup using the larger 17m² wing they had made.
When this photo was taken, the wind was too light for the funboarders to race. They waited
on the beach.It was possible to ski with 5-6 knots wind,
with the limiting factor being the ability to relaunch the wing. |
A long search and dozains prototypes later the stability
problem had been solved by 1988-89. The refined design was also of lighter, single skin
construction; much easier to launch and control. The kite was almost ready for
production, but they still had not found skis or a board able to go upwind. Sure, they had
made at least 10 boat prototypes with good upwind ability, but they were either too large,
too heavy or too costly, bearing in mind that they had a design target of under two metres
in length and less than 10 kg in weight.
Attached to the front beam of a 3m rigid catamaran,
launching the cat was easy. (For steady steady winds only!) |
