Duprey This is Wally’sforay into the
power yacht
market with a
stealthlike yacht,
which has gas
turbines that can
take her over the
60 knot barrier. > ith the whistling of the gasturbines over the fine plumes of
spray which rise up from the
wake one has the feeling of beinginvolved in some kind of futuristic adventure
film on board an extraordinary yacht,
designed to break through the 60 knot
barrier, with the earthly backdrop of
Portofino slipping away in the distance.
Nestled beneath the striking prism-shaped
glass and carbon deckhouse that covers the
12 metre long loft-style interior with its
panoramic views, those on board get their
first taste of the phenomenal acceleration ofthis Italian high speed demon.Italian industrialist Luca Bassani, founderand chairman of Wally, stands at one of the
two navigation consoles, piloting the first 118
Wallypower with great dexterity as he starts
up the three propulsion waterjets. Ten
seconds later, the 95 tonne boat gently lifts
off the water and skims over the surface,
although just moments before she had been
travelling at only 9 knots under her two
370hp Cummins diesel engines. She reaches
35 knots with no vibration whatsoever, and accelerates steadily up to 45 knots without
any jerkiness. It is only when you glance at
the GPS that you realise that the yacht is
already at her cruising speed.The deep-V hull with its knife-edge bowmakes short work of the first waves whipped
up by a fresh southwesterly. Bassani
expresses his satisfaction when the hull,
designed to pierce the waves, effectively
absorbes any pitching and achieves a 50
percent reduction in vertical acceleration.At 50 knots the boat starts to reactforcefully to the succession of 1.5 metre-high
waves, and we had to hold on tight after the
abrupt return moment of the side hull steps
that assist in roll stability. Bassani is
reassuring, announcing that this movement
will be distinctly lessened when the angle of
incidence of the steps is corrected and the
flexible elements designed by the Wally
research department are added.With the swell three-quarters on the stern,the 118 Wallypower is on an ideal trajectory
for reaching 60 knots. However, as the sea is
some 31 degrees and the air temperature 33
degrees, the three gas turbines do not yield
their full power of 16,800hp as they would if
the sea temperature were 15 degrees.
Bassani explains that the pitch of the
propellers in the KaMeWa waterjets is too
fine – they will have to be adjusted for the
boat to be in its optimum configuration for
achieving 60 knots. Hence on this occasion it
does not manage to exceed 54.8 knots.Admittedly this is far from the 65 knotsclaimed by Wally, but the yacht’s very
balanced handling at over 50 knots should
allow her to reach this speed quite
comfortably with a good safety margin. As
Bassani adds, ‘The real challenge is to be fast
in all sea conditions. Most of today’s fast
boats are obliged to slow to below 20 knots
60 to 70 percent of the time. So we have
gone for this deep-V hull form with no flaps, 68 BOAT INTERNATIONAL BLACKYELLOWMAGENTACYAN BI209_43697_03_WALLY1_2.pgs 24.09.2003 10:23
