HISTORY
 118 WallyPower
is a 118-foot (36 m) luxury yacht with a maximum speed of 60 knots
(70 mph, 110 km/h) produced by Wally Yachts. The yacht is narrow and
angular in design with black glass housing, driven by three Vericor
TF50 gas turbines generating 5600 hp, each driving a Rolls-Royce
Kamewa water jet, two steerable outboard and a non-steering booster
on the centerline. The steerable water jets also have a diesel
engine input for a 370 hp (280 kW) Cummins diesel, and are thus
Combined Diesel or Gas Turbine (CODOG). The total power output it
16,800 hp. One 118 WallyPower has been constructed, and is in the
Mediterranean as of 2008.
Construction
The hull of the 118 WallyPower is the result of an extensive R&D
program including tank testing at the SSPA facility in Gothenburg,
Sweden, and smoke testing in the Ferrari Wind Tunnel Facility in
Maranello, Italy. It is stable at speed as a result of the deep V
(22 degrees) hull shape and a straight stem bow designed to pierce
waves.
The air inlets of the gas turbines were optimized to minimize any
turbulence and back flow of the exhaust gas on deck and living
areas. The bottom of the hull is solid fiberglass. Topsides, from
the waterline up, are hybrid fiberglass/carbon composite with balsa
core. The deck is a Nomex/full carbon composite. The deck
superstructure is made of a carbon frame to which glass panels are
glued. The glass is composed of Lexan and a triple laminate of
glass. The interior bulkheads and cabin soles carry no structural
loads, so they are made of thin wood and laminate veneer skins with
cores. The bath fixtures and dining tables are made from carbon
composites to reduce weight.
The paint finish is metallic dark green, and changes reflections and
colour depending on the light and landscape. The 118's deck,
cockpit, navigation, dining and saloon areas have been designed as
one continuous element. The open space incorporates three areas,
from stern to bow: the saloon, the dining/seating area, and the
navigation cockpit. There is a 360-degree view from the dining area.
Underneath the 8-place dining table is a skylight which illuminates
the lower corridor. The dining and lounge cockpit is forward of the
superstructure for privacy, and away from the heat of engines. Two
fore dining tables can be mechanically lowered into place in the
bow. The deck of the Wally 118 has a hidden crane and compartment
for a tender. The boat also features 6 plasma screen TVs.
Inside, the owner’s stateroom is forward, lighted by a top skylight,
and has a king-size bed and side cabinets and his and hers en-suit
bathrooms. Two identical guest cabins have queen-size beds and
en-suite bathrooms. The stainless steel galley (kitchen), which
includes the crew mess, has an oven, stove, television, and
refrigerators.
Technical Specifications
The price of the 118 Wallypower is US$33 million for the triple gas
turbine version, or $22 million for twin diesels. It has a range of
1,500 nautical miles (2,800 km) at 9 knots (17 km/h), or 300
nautical miles (560 km) at 60 knots (110 km/h). Fuel capacity is
22,000 liters (5800 US gallons). At the maximum speed of 60 knots
(110 km/h) the gas turbine uses 15 US gallons / 58 liters of fuel
per nautical mile, 900 gallons / 3500 liters per hour. The boat
displaces 95 tons and can accommodate 6 guests and 6 crew
Awards
The 118 WallyPower won the MYDA, Millennium Yacht Design Award,
organized by Seatec (the yachting and shipping technology show of
Carrarafiere) for the "Layout of the Third Millennium." It was the
sole boat in the San Francisco Museum of Modern Art architecture and
design exhibition (2004/5), 'Glamour: Fabricating Affluence
Popular Culture
The 118 WallyPower has appeared in popular UK car programme Top Gear
as well as the movie The Island.
