New Zealand
super maxi 'Alfa Romeo' has the potential to shatter race
records around the world, predicts owner and skipper,
Neville Crichton, having spent two weeks testing the new
super maxi prior to the Hahn Premium Race Week at Hamilton
Island (20-27 August 2005).
After the Whit Sunday's regatta, the first major record in the
sights of Neville Crichton is the Rolex Sydney Hobart Yacht
Race mark of 1 day 19 hours 48 minutes 02 seconds for the
628 nautical mile race in the Tasman Sea. "Given a
relatively constant breeze of 15 knots with slightly sprung
sheets the new boat will average 22 knots and we can sail
the course in 1 day and 5 hours," he says with confidence.
The new 'Alfa Romeo', the 30-metre (98-feet) successor to
the 27.5-metre (90-feet) world champion of the same name
that took line honours in some 74 races in the Southern and
Northern Hemispheres, including the 2002 Rolex Sydney Hobart
Yacht Race, is the most technically advanced ocean racing
yacht in the world today. She is a magnificent example of
the latest concept in design, engineering, construction,
rigging and sails.
Designed by the US firm of Reichel/Pugh and built of carbon
fibre composite by McConaghy Boats in Sydney, Australia,
'Alfa Romeo' carries a towering 44 metre carbon fibre mast
built by Southern Spars in New Zealand with the latest
concept in 3DL and mylar sails designed by the Sydney loft
of North Sails. Each company has contributed to a racing
yacht that can only be described as awesome in concept and a
quantum leap in the already advanced technology of modern
yacht design, engineering and construction. McConaghy Boats,
who have now built 10 maxi yachts in carbon fibre describe
the building of 'Alfa Romeo' as the biggest and most complex
project they have ever undertaken.
Race performances are expected to be just as awesome with
race record predictions no idle threat. Overseas in 2006 the
new 'Alfa Romeo' will be an outstanding example of
Australian and New Zealand boat-building techniques and
workmanship. Like her predecessor, she is registered with
the Royal New Zealand Yacht Squadron in Auckland and carries
the sail number NZL 80.
'Alfa Romeo' will begin her racing campaign at the Hahn
Premium Race Week at Hamilton Island later this month, from
20-27 August. She will then be sailed to New Zealand for
some final checkout before returning to Sydney in October to
begin an intensive lead-up campaign for the 2005 Rolex
Challenge and the Rolex Sydney Hobart Yacht Race. In January
she will be shipped to Europe to contest all the major
offshore events in the Mediterranean and other Northern
Hemisphere waters.
Owner/skipper Neville Crichton, a lifelong sailing
enthusiast and, in his own right, a world class racing
helmsman, commissioned Reichel/Pugh to design him a super
maxi boat to the 30-metre length overall (LOA) maximum set
for two of the world's great traditional races, the Rolex
Sydney Hobart Yacht Race and the Rolex Fastnet Race. "I
would have liked to stay with a 90-footer but when the CYCA
(Cruising Yacht Club of Australia) and the RORC (Royal Ocean
Racing Club) set their maximum LOA at 30-metres for the
Hobart and the Fastnet Races we had to go up to 30-metres to
be competitive," Crichton explains.
As it is, the new 'Alfa Romeo' will face some strong
competition in the 2005 Rolex Sydney Hobart Race with four
other maximum LOA boats expected to compete in the 2005
race - the new Maximus, owned by fellow New Zealanders
Charles St Clair Brown and Bill Buckley, the rebuilt
Australian boat Skandia, owned by Grant Wharington, a
yet-to-be-launched new Wild Oats for Bob Oatley, and another
New Zealand boat, Stewart Thwaites' Konica Minolta which,
like Skandia, raced to Hobart last year - and also did not
make it. "The 2005 Rolex Sydney Hobart Yacht Race is shaping
up as an extraordinary clash of the super maxis and a race
that could well see the record broken," predicts Crichton.
"Around the world we will see race records shattered by this
new breed of yachts."
Although the new 'Alfa Romeo' has yet to sail in fresh to
strong breezes, Neville Crichton and his crew are predicting
amazing numbers from the new 98-footer. "My gut feeling is
that she will be 20 per cent faster than the previous
90-footer capable of 35 knots downwind in any sort of a
reasonable fresh breeze; 20-22 knots on a reach in 18 knots
of wind; 12 knots hard on the breeze to windward. The big
difference is that this new breed of 30-metre boats are
capable of sustaining high speeds," says Crichton. "If we
can get 15 knots of constant breeze all the way to Hobart we
will break Nokia's record!"
"Of course, it all hinges on the weather. The Hobart record
set by Kialoa stood for 21 years, until just bettered by
Morning Glory in 1996. Then Nokia shattered that time in
1999. "If we get the same conditions as Nokia, strong winds
on the beam, we could do it in a day but realistically we
could reach Hobart this year in a day and five hours."
When he commissioned this new boat, Crichton himself was
making a quantum leap forward in the many yachts he has
campaigned so successfully. Not only would the new 'Alfa
Romeo' be the biggest racing yacht he had ever owned, but it
would be the first for him with a canting keel. While he
says that there is not a lot more that can be done in
developing super yachts sailed by small crews, some
significant advances have been made with the new boat. In
addition to the canting keel the boat has water ballast, two
rudders fore and aft of the keel and hydraulic winches. The
rig is taller than any super maxi built to date, enabling
the boat to carry a huge mainsail and massive asymmetric
spinnakers.
CONSTRUCTION: The planning, engineering and building
of the hull, keel and rudders of 'Alfa Romeo', the 10th
maxi yacht built in carbon fibre composite by McConaghy
Boats in the Sydney, Australia, was the biggest and most
complex project yet completed by the internationally
renowned boat-builders. From a male plug, McConaghy's built
the carbon fibre composite hull using the latest prepreg
systems developed by Structural Polymer Systems (SP) which
sent out from England three of their technical experts to
assist with the project. Extensive use was made of high
modulus carbon fibre over the Nomex honeycomb, with Corecell
foam used in high load areas. Because the hull is so narrow,
many longitudal stiffening planks were also used for added
strength. Having the canting keel operated by a single
hydraulic ram added to complexities of the engineering as
did the extensive electronic control systems required for
the canting keel, the two rudders and the hydraulic
winches. Precision alignment of bulkheads and canting keel
structure was critical, with all jigs being computer
milled. Highly specialised steels were also used for the
components of the hydraulic ram which was built by Central
Coast Hydraulics. "It was a new generation of complexities
in boat building," a spokesman for McConaghy Boats added.
THE HULL: The metallic silver painted hull is long
and lean-looking with a short bowsprit. The coachhouse is
low and encases the hydraulic systems that control the jib
cars and Cunningham controls. The open cockpit runs from aft
of the coachhouse and main companionway to the transom,
clear except for the twin steering wheels set on stylish
individual consoles with instruments in front of the
helmsman. Instruments are repeated on the mast. Remarkably,
the new bigger boat still weighs only about a tonne more
than the previous 'Alfa Romeo'.

BELOW DECKS: The stylish interior is white with
highlights of black carbon fibre and warm red upholstery for
the bunks/seat. Even the toilette is carbon fibre! A large
part of the accommodation is taken up with the encased
engine, the twin hydraulic systems (for keel and winches)
and encased electronic systems, with the fully equipped nav
station set just below the helmsman's position on deck.
Apart from through the main companionway, light comes into
the interior through a series of small ports through the
deck and with the white interior the long open saloon (for
want of a better description) is quiet light and airy -
except the dark cave at the bow which houses the forward
rudder controls. A carbon fibre table in the shape of a
water drop hangs from the deckhead just aft of the galley
but the focal point is the canting keel system which can be
viewed through a polycarbonate clear cover. You can even see
the water below!
RUDDERS: The two rudders are solid, high modulus
carbon fibre for added strength, as are the rudder
stocks. The rudder bearings are 400mm metal, custom made by
a Berry, NSW, based company called Private Part. The forward
rudder, controlled by a massive hydraulic arm in the
forepeak, can be used three ways in conjunction with the
main steering rudder - offset at an angle of up to 2 degrees
to give the boat extra lift when sailing to windward; fixed
to work in tandem with the main rudder; or "floating" when
running downwind. The main rudder blade incorporates a
"string pot" positive sensing device which instantly detects
the angle of the rudder. This is fed into the boat's
computer system which then tells the hydraulic ram exactly
the angle to position the forward rudder.
CANTING KEEL: The canting keel is high tensile steel
with a special calcium lead bulb and is controlled by a
single hydraulic ram which can swing the keel 45 degrees
either way from the vertical. "We felt that it was better to
have one over-built ram than two rams," says Crichton. "In
fact, probably the whole boat is probably over-built." The
canting keel system meets the new international rules
requiring recovery angles and back-up systems, both
mechanical and hydraulic introduced following the capsize of
Skandia in the 2005 Rolex Sydney Hobart Race. For the 2005
Rolex Sydney Hobart Race, 'Alfa Romeo' will have on board a
specialist canting keel technician who has a specially built
console on deck aft of the twin steering wheels. "I fought
against canting keels, they add to the design and
engineering costs," Crichton points out, before adding: "If
properly engineered, they are no problem in the operation of
the boat and they do improve the performance."
WATER BALLAST: In addition to the canting keel,
'Alfa Romeo' has water ballast. The equivalent - or more -
of having the entire crew standing at the transom!
ENGINE POWER: Power to drive the boat at up 13 knots,
plus the two hydraulic systems for the canting keel ram and
the deck winches, comes from a Yanmar 250 horsepower
engine. McConaghy Boats have also designed a special
propeller retraction unit which lifts the five-blade fixed
prop back into the hull, leaving a flush surface when under
sail.
RIG: Towering just over 42-metres above the deck, the
Southern Spars carbon fibre mast is superbly finished and
shaped, with a five-spreader in-line rig. Standing rigging
is no longer metallic. It is PBO rope - a composite that is
not only stronger but 30 per cent lighter than the once
conventional stainless steel rigging and even lighter than
carbon fibre rigging. Running backstays and two sets of
check stays and an inner forestay control the mast shape.
SAILS: A major factor in deciding the sail inventory
for the new boat has the CYCA's decision to drop the
previous upper speed limit, a computer handicap figure, for
the 2005 Rolex Sydney Hobart Yacht Race. Thus, the sails are
bigger, the huge reaching spinnakers lighter - the biggest
is 805 square metres. By comparison, the new 98-footer will
carry 35 per cent more sail area than the 2002-built 'Alfa
Romeo'. North Sails in Sydney have once designed all the 3DL
working sails and spinnkers, the spinnakers cut in the
Sydney loft, the working sails imported from the USA. For
the 2005 Rolex Sydney Hobart, the new boat's working sails
will comprise an offshore mainsail with headsails comprising
a #1 light/medium, #1 heavy, #4 heavyweight jib, #5
heavyweight jib, jib topsail, genoa staysail and a drifter
windseeker. The reaching and running sails will comprise a
Code 0 and six asymmetric spinnakers - #1A (VMG), #2R
(running), #3A (VMG), #4A (heavy running), #5A (heavy
running) and #6A (very heavy running) plus the mandatory
storm trysail and storm jib. The offshore main is 314 square
metres, the #1 genoa 208 square metres and the biggest
spinnaker is 805 square metres. The spinnakers are flatter,
similar to those carried by 18-foot skiffs, to enable the
super maxi to sail much close to the apparent wind.
WINCHES: All winches are the very latest from Harken.
The four primary winches are new generation 1130s, three
speed hydraulically-powered, push-button operated with
carbon fibre tops. They are capable of 90-metres a minute in
first speed and have a safety rating of nine tonnes. The
runner and mainsheet (AC65.2) traveller winches are also
hydraulically operated but the four AC990 pit winches are
manually operated.
THE CREW: 'Alfa Romeo' will be sailed to Hobart by a
crew of 20, including the canting keel technician and a
dedicated navigator. The previous 90-foot 'Alfa Romeo'
Shockwave raced to Hobart with a crew of 24. There will be
five designated helmsmen, including Crichton himself and
sailing master Michael Coxon whose company, North Sails
Australia, has built the 3DL sails for the boat.
The new 'Alfa Romeo' has been designed as an all-round boat
for offshore racing, not a boat for square running but one
with a strong upwind performance and capable of fast
reaching. "In the Med most of the courses are upwind with
some reaching legs; these days we gibe downwind to achieve
the optimum angles and that is what we will be doing to
Hobart," says Crichton.
As the Kiwi yachtsman says, the competition for line
honours in this year's Rolex Sydney Hobart Yacht Race will
be the toughest ever, "unbelievably close" but he is
confident that the new 'Alfa Romeo' will repeat the
remarkable racing record of the 90-footer he sailed to a
Hobart Race line honours win in 2002 and then in both 2003 and
2004 went on to conquer the world's best maxis in the
Northern Hemisphere.
