“If you can dream it, Perini will find a way to build it.
To me, that challenge is why you build a boat”
The master suite takes advantage of the yacht’s full 13m beam to include an office area and a king-sized bed in natural surroundings of American ashhad committed to move from the 56 metre to the
60 metre model. We developed this fully custom
all aluminium hull interpretation of the 60
especially for him. It has serious performance
capability, compared with other recent launches.
On a scale of Seahawk to P2, it’s more like P2.”
So determined was he to wring every bit of
performance out of Perini, Duker brought naval
architect Philippe Briand into the mix to evaluate
and fine tune the builder’s design work. “The
design of the yacht existed, the GA existed and
the initial naval architectural plans had been
drawn,” says Briand. “The specifications, the
main dimensions, the displacement, the centres
of gravity and the height of the masts, as well
as draught, [had been] defined and approved
by the owner. For the final stages, we worked
on the hull lines, the appendages and the sailplan.
It is a bigger intellectual challenge to [re]design
the existing [hull] for tomorrow as opposed to
start from scratch.”
In 2012, Briand’s office conducted CFD tests of
the hull lines and made 37 changes, including
modifying the waterline length and wetted
surface and redrawing the bow and stern shapes.
The swing keel and single rudder were optimised,
as was the vessel’s stability versus overall weight.
Calling the owner a forward thinking man with
very modern tastes, Perini design chief Franco
Romani said the brief challenged his team “to
create a new interpretation of their design
language. The near vertical bow combined with
the low profile superstructure has resulted in a
new look for Perini”.
Perhaps the biggest change was moving the
mizzen mast back 3.3 metres to improve airflow
over the mizzen sail for more driving force and to
create space for a mizzen staysail. This sail, flown
in apparent winds of 50 to 100 degrees, adds
0.6 knots of speed. “It wasn’t our intention to
design a racing yacht,” says Briand, “but we can
guarantee she is a cruising yacht with the
potential of sailing excitement.”
In its turn, Perini upped the performance of
its electric furling drums and captive sheeting
winches, delivering speeds beyond those of its
previous benchmark, Seahawk. The powerful
sailplan uses North Sails’ 3Di technology and
relies on two carbon fibre masts stretching 71.59
metres and 60.96 metres above the water,
supplied by Rondal, with Carbolink composite
stays and Kevlar running rigging. Controlled by
Perini’s latest generation electric winches and
software, the system allows the yacht to be sailed
entirely from the cockpit consoles.
Sybaris is also breaking new ground for the
builder in terms of power management. Two
variable speed generators supply electrical power
via a DC bus to the vessel’s main electrical grid0123456789 0123456789123
