Launch of the GC32 with the new L-foils and T-rudders

Clean Report

More than 18 months ago, just a month after ETNZ revealed their AC72 was a flying boat and lured by the potential for a 32-foot version of it, I spent 12 hours flying to Dubai just to check out the brand new GreatCup 32 catamaran from F-18 sailor Laurent Lenne and designer Martin Fischer.  I took a cab straight to the Dubai Marine Center, and an hour later, we were sailing the sleek carbon cat in 8 knots of Arabian breeze.  And 20 minutes after that, the boat was broken.

Needless to say, I was underwhelmed.  The Southern Spars-built spine of the boat wasn’t right, and I wasted a couple of days in a plane to find it out.  To compound matters, it was pretty clear that the intricate, Alinghi 90-style S-shaped foils were cool-looking, but lacked true foiling ability.  They reduced displacement, but only in very specific conditions would they lift the boat out of the water and create anything that could be called stable flight.

But Fischer, Lenne, and Aussie project manager/COO (and longtime SA’er) Andrew “Macca” McPherson had just seen the future in the form of a flying red-and-black carpet in Auckland, and they were already planning on meeting it.  They spent much of 2013 studying, learning, and redesigning the foil system for the GC32, and while they didn’t put a ton of effort into selling a boat they knew was in the midst of a big change, they quietly sailed a 4-boat, 4-event Great Cup series in Europe.  And they kept working.

Fast forward to April, when I got a call from Lenne.  ”They’re ready,” he told me.  ”And you should get your butt over here.”  Hours after Charleston Race Week ended, I jumped on a plane from Charleston to JFK to Paris to Marseilles, and made my way to one of Europe’s biggest marinas in La Grand Motte, France.

An intense design process had led Fischer to a ETNZ72/Flying Phantom/Groupama C-Class style foil solution, with acute-angled, rake-adjustable J-boards with a massive 1.2m span, and adjustable t-foil rudders like a Moth.  Built by Heol, supplier of foils for just about every major French racing multihull for the past decade, the foils are serious pieces of machinery – a single dagger supports almost the entire weight of the nearly one-ton cat and its crew, is built under a massive 8 Bar of pressure, and weighs some 50 KG.  The good news is that you don’t often take them out; they insert from the bottom and retract up to the hull, allowing you to beach or ramp launch the boat with no hassle.

Launch of the GC32 with the new L-foils and T-ruddersBut even if they were a big hassle, it would be worth it, because after three days of sailing the GC-32, I can honestly say that this boat has the potential to change multihull racing forever – all of a sudden, non-foilers just seem kind of silly.  They’re slower, less forgiving, harder to sail, more loaded up, and just nowhere near as fun.  I’m leaving for the airport in just a few minutes and there is a long, comprehensive video being put together next week with all the details, so I’m going to keep this short, but after crewing, driving, filming, and spectating for the past 3 days in winds from 5 knots to 30 knots, it’s very clear that this boat is something entirely new.

What do I mean by that?  How about some numbers:  22 knots upwind at 44-50 degrees TWA, with more than 5 degrees of windward heel – almost like a moth.  32.7 knots downwind on the boat’s fourth day in the water, with too much sail area and old sails designed for a skimmer.  And our gybing angles, confirmed by Velocitek GPS replay?  40 degrees.  In other words, this boat sails downwind at roughly the exact same angles as an AC-72, and 80% of the speed, with a quarter the crew.  And at 235K Euro, it’s around 1% of the cost.

Far more importantly, a no-talent hack like me can EASILY drive the thing.  This is no joke – the GC32′s huge vertical lifting surfaces are nearly as big as those on the Oracle 72, and that means when you do something stupid – which I did plenty of – you don’t crash down like a Moth or AC72, and if you press too hard and get too much heel on, the boat gently slips sideways rather than pitching you over into the piss.  I hit 24.4 knots yesterday in 14 knots of wind, heating up to pass a fleet of Fireballs rounding the top mark off Montpellier beach…the lead boat just stopped and stared and let his competition sail by him.  An excellent driver like Macca or Adam Piggot only got to 26 – if I can do 90% of their speed, truly anyone can.  In other words, you don’t need to have Bora Gulari’s cat-like reflexes, Jimmy Spithill’s iron balls, or Larry Ellison’s mountains of money.  Just a couple hundred grand and a desire to fly.  The Daily Sail’s James Boyd hit 20.2 on Monday, so at the moment I am the fastest 32-foot foiling cat driving media person in the world –  a title I will wear with pride.  Back on you, Boydie.

More to come, and big thanks to Sander Van Der Borch for the gorgeous shots.  There’s more info and some data in the thread.

Remember when we announced the ‘flying’ Great Cup 32 Catamaran more than a year ago?   With its ‘compound W’ daggerboard shape and L-foil rudders, the Martin Fischer-designed boat looked slick, modern and sexy.  They even sold a few, raced a couple of regattas, and last month, pulled off a demo day in massive waves and 25+ in Nice while the Extreme 40s were sitting at the dock.

The main problem?  High performance foil design changed more in one year than it has in decades. Essentially, if you have a new ultra-performance multihull these days and you’re not flying, you’re failing – and the GC32 foil package was doing just that.

In the meantime, the AC72 showed everyone the way, and Fischer’s work on both the Groupama C foiler and the Flying Phantom project gave him the inspiration he needed to turn the 32 into a full foiler, and you can check it out above and here.  Sea trials will happen in France around the New Year.
