The
development was done by world renowned designers, Melvin &
Morrelli for hulls, Niels Bunkenburg, A cat guru for the foils,
Performance Sails for the rig & sails combined with the in-house
knowledge at Nacra.
Development
and testing has been underway for over 18 months, 2 boats were
fitted with both straight daggers and with foils to allow the
team to compare; a third boat, a Nacra 20 was fitted with the
wide beams and the new rig. The 3 test platforms allowed the
development team to test in the real world without revealing to
much about this new boat, so they could adjust and fine-tune the
design.
A variety in
masts, mast hardware positioning and different sail cloth and
shapes has been tested. The new hull shape which has been
created, starting with a wave piercing bow forming a diamond
shape hull stretching backwards into a “square-isch” transom, is
of mayor importance due to the combination with the curved
dagger board.
Although the basic shape was chosen, several adjustments were
made driven by new technology [computer fluid dynamics] and
knowledge which was gathered by Melvin & Morrelli while working
on the Americas Cup project for BMW ORACLE.
Pete Melvin:
"It is not a coincidence that the hull shape of the new F20
Carbon shows resemblance with the floats of the AC boat, we were
able to take the knowledge we gained at the AC project and scale
it down to the F20 Carbon. The most noticeable and distinctive
feature is the chine that runs from the bow backwards on the
hull allowing the water to flow away from the hull. Combining
the chine and wave piercing bow with the upper deck shape
reduces drag piercing trough the waves both upwards and
downwards”.
Regular
production will start any moment and the first boats will be
ready to be delivered to the customers in the first months of
2010.
