The new Perini Navi 60m Seahawk, a natural
evolution of the series of Perini 56m sailing
yachts of which ten have been launched to
date, is especially fast and extremely comfort-
able with abundant outdoor spaces. Numerous
design, technology and architectural innova-
tions are present on this new type of sailing

he hull, designed by Perini Navi in collabora-
tion with Ron Holland, is even more sleek than
her predecessor and has a perfect proportion between
her waterline of 50.43m and her maximum beam of
11.40m making for a very fast yacht.
With a hull and superstructure in aluminium, the
yacht has an optimized displacement of 570 tons and
a tonnage of less than 500 tons, within the limits for
a certain type of vessel.
The yacht’s lifting keel also has some important in-
novations: a new shape will allow for better speed and
efficiency. The draught ranges from 4.30m to 12.30.
A new generation of Perini Navi captive reel win-
ches has been created and installed on this yacht. The
winches were designed and constructed by the Peri-
ni Navi Mast Department to assure stronger reeling
power and faster manoeuvring. For the jib sail these
new winches can reel in a maximum weight of 30
tons at a speed of 40m per minute. They are managed
from a dedicated sensor to assure top performance no
matter what the weather conditions may be. The in-
novative sensors can measure the load and regulate
the reeling speed to the maximum possible.
These winches are smaller than the previous Perini
captive reel winches thanks to the use of new mate-
rials that are lighter weight and more efficient.
Completely redesigned using state of the art mate-
rials, the head sail furlers are not only much more
powerful than they were on previous Perini yachts
but they are also built with their motors under the
deck. The motors are designed with hydraulic cylin-
ders that can regulate tension on the Cunningham.
Not only functionality but design are greatly impro-
ved by these innovations.
New and innovative tracks that are small but can ca-
rry loads of up to 30 tons have been installed for the
headsail sheets. Performance and safety are guaranteed
by the use of materials such as extra resistant steel and
titanium in these components.
Thanks to this innovation the lateral passages of the
yacht are uncluttered and safer while the yacht looks
leaner and fast.
Seahawk is a ketch with a total sail plan of 2,125
square meters mounted on two aluminium masts. The
main mast is 62m high and the mizzen is 52m. The
boom is in carbon fibre as are the spreaders, the fores-
tay foils and the diagonals. And for the first time on a
Perini Navi ketch, carbon fibre has been used for the
standing rigging.
The masts have benefited from Perini Navi’s advan-
ced research in the area of structural design; research
has made for the construction of lighter weight masts
that are stronger than ever. Optimization was aimed
primarily at areas such as materials and structural
reinforcements. The result has been that the sum of
Seahawk’s two masts equals the weight of the main
mast alone on the first 56m launched, Burrasca in
2003. The decreased weight is accompanied by in-
creased performance and has allowed for 70 tons less
ballast in the keel and a lighter displacement.
Following up on feedback received over the years
from other yachts in the Perini Navi fleet, the organi-
zation of the mast base area has been completely chan-
ged with the creation of a new structure that makes
pre-tensioning of the mast much simpler, allowing for
more precise load calculations and greater safety.
On the mast head halyards have new and simpler
routes, there are new lighting supports and new elec-
tronic instruments that make sail handling simpler.
This project of innovation was carried out in colla-
boration with Lloyd Register of London that certified
it. The final result has been a simpler production pro-
cess and masts that are both more rigid and better
performing. Mast structure: laminates and reinforce-
ments.Also for the first time, new inspection hatches
have been built along the mast so that it is easy to
check on the structure and fix any problems that may
arise with halyards and other internal components.
In terms of design, the yacht’s layout has been com-
pletely revisited with a lighter and smaller coachroof
and superstructure. This project is a standout for the
abundance of exterior living spaces with both fore and
