Auckland’s Viaduct Harbour showcased a glimpse into the future of the America’s Cup with the debut of the wing-sailed AC45 catamaran. The forerunner to the next generation of America’s Cup boats, the AC45 made its maiden voyage, the first of many sea trials planned over the coming weeks.


“Thanks to the efficiency of the New Zealand boat building industry and a huge effort by our team, the first AC45 is now ready for sea trials just a mere four months after this exciting new multihull class was first conceptualized,” said Tim Smyth, co-construction manager for Core Builders Composites of Warkworth, New Zealand.

The AC45 will be the centerpiece of the 2011-2012 America’s Cup World Series, which will start mid-2011. The high-tech carbon fibre catamaran is the first in a fleet of the new 45-foot one-designs that will be tested by America’s Cup teams before racing on the America’s Cup World Series circuit.

The AC45 is an essential element of the vision for the 34th America’s Cup, which will feature 72-foot catamarans raced on San Francisco Bay in 2013. Focused on creating more on-the-water excitement for both the teams and the fans, the AC45 is designed for both speed and close racing. While capable of closing speeds of up to 30 knots, the AC45 was designed to remain nimble enough to handle the tight race courses planned by America’s Cup Race Management (ACRM).

“The biggest challenge with multihulls is learning how much to anticipate. With the AC45 being a big, powerful multihull capable of tripling the wind speed, your reactions and skills are accelerated. It’s all about being ahead of the cycle,” said ORACLE RACING skipper James Spithill. “I think the AC45 will enable all teams to advance to hard-core race mentality very quickly.”

The AC45 was designed by the ORACLE RACING design and engineering team, which developed the catamaran on behalf of the America’s Cup community. At task was designing a boat that would not only meet the racing criteria, but could also fit inside a 40-foot container, which is the shipping vessel for the America’s Cup World Series.

“The boat was designed for all-around performance so it can be sailed in wide range of conditions, and that means the next America's Cup will see races start on time,” said Ian Burns, ORACLE RACING design coordinator. “Plus it’s a regatta boat, meant for lots of racing, so quick assembly and disassembly was a must to accommodate an active competition schedule.”

The AC45 had to be robust enough to sail through a wide wind range, from 5 to 30 knots, as well as survive in the event of collisions, which are foreseen as teams learn to adapt to multihull closing speeds.

Utilizing the same technology used in the aerospace industry, the hulls are built in carbon epoxy with honeycomb cores, making them extremely stiff and light structures. The sandwich construction involves two carbon skins less than 1mm thick laminated over an ultra-light honeycomb core.

“The new America’s Cup is for those who are hungry for a challenge and the AC45 is really a fresh take on the multihull,” said Vincenzo Onorato, President, Mascalzone Latino.

“We plan to run tight race courses that will force boats to engage with each other, creating really close racing situations. Multihulls are very fast boats and will therefore reach the course boundaries sooner, so races will become a true test of skill and strategy, not just speed,” said Iain Murray, CEO, America’s Cup Race Management and Regatta Director. “The AC45 will fast-track teams to state-of-the-art wingsail technology and crew technique in the first season, and will greatly prepare them for the AC72.”

There is good new, it floats, sails forward, the mast works and other items.

The AC45 also had headsail flying,

Remarkable turn a round time. 4 months from conception to sailing.

I know people who take longer to get dressed. We'll see these in September?

Hang on to the mid-pole, tighten the nets when we get ashore.

"It’s fantastic ...everyone at the dock is smiling. It’s an awesome tool and it’ll be a lot of fun.”

The first ACRM took to Auckland’s Waitemata Harbour on Monday 17 January, the first physical manifestation of the transformed 34th America’s Cup.

The very first AC45 clocked 23 knots in just 10 knots of breeze on its first sail; a very satisfying reward to the designers, engineers, boatbuilders and shore team for four months of dedicated work.

“The wing’s big and the boat powers up quickly and is easy to sail and maneuverability is not a problem. Straight off the bat we were talking about going racing and how good it is going to be,” said Spithill, the designated shake-down skipper during builder’s acceptance trials before Hull #1 is handed over to owners ACRM.

“The wing sail is so much quicker to unload than a main – with the wing it’s instant. Teams will get up to speed quickly with these boats and they should be really happy with them,” added Spithill.

“From a boat off a piece of paper to its first sail, it’s the most impressive I’ve ever seen. Within minutes we were flying a hull and fully loaded. We have the latest technology here with the wing and that’s what the America’s Cup is all about.”

A decent breeze and two hours of sunshine were about as ideal as you could for a maiden sail. “I can’t wait to get afloat again,” said Spithill.
