7,5 0pen, one year later
français
0ne year ago was lauching the first 7 ' 50 Open designed by Group
Finot for JPS Productions. Since, this" day-boat fun " be noticed in regatta for
her lightning accelerations and his "glide". First balance with Nicolas
Groleau, technical responsible for the project, and Thierry Fagnent
responsible for the shipyard AMCO who builds this sailboat.
Nicolas Groleau :
"Considering a technical and sports point of view, I think that she
is a total success. She sails well beyond our expectations. We wished amonotype very
different of the other sailboats: faster, easier, more pleasant. A classical boat becomes
" amusing " when wind is 20/25 knots, 750 is planing from
10/12 knots and no problem until 30/35 knots!
She is much easier to lead a 7,5' than a Class 8 for example. At the beginning we wanted
to realize a monohull 60' open in reduced size. In fact she is more lively than her great
sisters because she wears more sail. Because we have not the same safety constraints, we
can exploit her at most .
7,5 open is more expensive than the equivalent competitive boats because we use high
technology, the same as we use for the 60'open.
At present, three unites are produced but quite a lot of potential customers turn all
around. This year, we hope to have some sales, we remain confident, we think that the
racers will be able to make the difference between the Open 7,5 and a more classical boat
like Melje 24. In June, our 7 ' 50 will be engaged in the "bol d'or" on the
Geneva lake where they will be able to seduce".
Thierry Fagnent
" A 7 ' 50 Open
is one meter longer than a proto 6 ' 50 for the Mini Transat and the 6,50 are also the
small scale models of monohulls 60' open.
With what we know about Mini, we expected so a boat15 % faster but if , tacking, their
speed are comparable, reaching, there is no comparison : the Open 7 ' 50 is a real airplane! About her
reactions in regattas, she is a little halfway between a monohull and a multihull. For
example, when reaching she tack at 90° from the wind as a multi
About performance,
we managed to go up until 25 knots on the GPS with wind 25/30 knots! On the market of the
24 ' there is quite a lot of people but we would indeed imagine within two years the
presence of 15/20 unites in three or four different harbors so that they can race
regularly. Wait and see".
