A Game of Two Starts…

Both Louis Vuitton semi-finals went to 2-1 in the third race…

Two races, two stories, two-one - all settled on the start line when Desafio and Luna Rossa positioned themselves to the right hand side of their respective opponents. And the right paid like a triple rollover lottery... So far, BMW Oracle haven’t been round a single mark in front of Luna Rossa – they have crossed one finish line ahead, by 13s in the second race. But in the third of the series, the Italians repeated their first race clean sweep to take a 31 second win. For Desafio it was a remarkable reversal after the previous defeats - they stuck a penalty on ETNZ in the pre-start, then took the right off the line and came home 1 minute 14 seconds in front.

So, the starts… Desafio turning over the Kiwis is going to get the most attention, so we’ll begin there. The penalty developed from Karol Jablonski, at the helm of Desafio, repeating the move that Jimmy Spithill used to win yesterday’s pre-start against Oracle. From the pin end entry, he bailed out of the dial-up onto starboard, and then gybed round onto port. It sets you up to leeward and if the other boat hasn’t got enough speed to get down and across your bow, you’ve got control.

Dean Barker, at the wheel of ETNZ, may well have been worried about this, or he may just have felt that it was time to try and stick another one on Jablonski - either way, he forced another dial-up, and Jablonski repeated his gybe move. But this time ETNZ tacked away a little too sharply, ended up real slow, and sure enough, Desafio completed the gybe with plenty of pace, came screaming in to leeward, got the overlap and now ETNZ were on the ropes. Barker tried to escape by gybing across Desafio’s bow, and gave away the penalty. From there it got worse for ETNZ, as Desafio tacked away to take the right-hand side of the line. The Kiwis didn’t have the time or position to shut the Spanish out at the boat, although ETNZ got tight to leeward and forced Desafio to tack away. But they were headed for the right hand side of the beat, the Speed Restriction - No Overtaking signs were up all over the race course and that was pretty much that. Game over and Desafio pull it back to 2-1.

Oracle’s start against Luna Rossa was just as interesting. When the pair turned back towards the line on their final approach, Dickson and Oracle defended the left - they headed for the starboard tack layline for the pin. Luna Rossa chased them down there, but seemed more than happy to let Oracle have the left – Spithill said afterwards that their call was to win the right. Luna Rossa tacked away to start on port at the boat, with Oracle starting on starboard at the pin. Game over and Luna Rossa pull out to a 2-1 lead.

The thing here is that you don’t need to be the come-back kings if you win first crosses. And you don’t win first crosses if you can’t win starts and/or pick the right side off the line. Oracle’s come from behind record is great for the spectators, but it indicates what must be a worrying weakness for the boys in white. And today they paid for it.

On the face of it, you’d have to say that Desafio’s overnight reconfiguration (both they and Oracle were issued with new certificates before the race) was more successful than Oracle’s. But I don’t think too much can be drawn from today – the pattern was exactly the same in both races, the right hand side dominated. But having said that, the very fact that Oracle and Desafio have changed something, indicates that they might think they are going a little too quick downwind, and perhaps those wings needed a tweak…

The other thing that changed out there today was Luna Rossa’s tactical approach – Jimmy Spithill admitted as much in the post-race interview. He reckoned they’d talked about it overnight and decided to keep it tighter, and they did so successfully. And what does this mean in the light of my comments yesterday - that the loose tactics were as much about racing an even opponent, as about Torben’s desire to back his hunches? It probably means I was talking rubbish, certainly wouldn’t be the first time - particularly because the alternative conclusion would be that Luna Rossa think they have the measure of Oracle… Now why do I think I'm going to regret even bringing that topic back up?

The Day of the Tight Deltas

Or one tight delta at least..

ETNZ let Desafio shave 3 seconds off yesterday’s winning margin, the Kiwis crossing the finish line 40 seconds in front of the Spanish to go 2-0 up in their Louis Vuitton Semi-final. But all the action was with Oracle and Luna Rossa - Oracle pegged it back to 1-1 with a finish margin of just 13s – which tells you about as much of the story as the opening credits of a James Bond movie. And that’s what it was - all gun-slinging melodrama compared to the subtle tragedy played out between ETNZ and Desafio.

Where to start? Well, at the start… when Luna Rossa’s Jimmy Spithill bore away out of their port entry dial-up, fell onto starboard, and then gybed round to port to chase Oracle. It was a brilliantly executed move (I wonder how long Jimmy’s had that one in the locker waiting for the right moment?). It allowed Luna Rossa to get to leeward and overlapped sufficiently to pressure Chris Dickson into keeping high as they both sailed out to the right. They ended up over the starboard tack layline for the committee boat. From there, Dickson never got back into it, Spithill always had his hand on the door back to the start line. Oracle made a move to try and sail over Luna Rossa, didn’t make it, and when they subsequently started to try and push Luna Rossa back to the line both boats were late. The trouble for Oracle was that they were later, with Luna Rossa half a length directly in front of them and slamming the door shut in Oracle’s face….

What we saw next was Luna Rossa make some phenomenal gains upwind, to lead at the top mark by 58s, only for Oracle to reverse them downwind, and cut the margin to just 20s at the leeward gate. Oracle then turned a 14s deficit at the second windward mark, into a 13s win by (to all intents and purposes) just sailing past the Italian boat. So have Luna Rossa traded too much upwind speed for too little down, and Oracle done the opposite? In a post race interview, Luna Rossa’s navigator, Michele Ivaldi, reckoned that the gains came too quickly for it to just be about speed, and looking back through the race, I’m inclined to agree with him. Oracle went up the second beat quicker, and their gains downwind came in big jumps when they obviously had better breeze.

The Valencia sea breeze can be incredibly streaky (I remember that from trying to two-boat test there), and we saw that today, with boats just a 100m apart (never mind the 1500m split achieved at one point) in different breezes. But we’ll see if Michele really meant it tomorrow morning, when Luna Rossa will have to file a new certificate if they’ve made any changes to the boat. Perhaps the truth is somewhere in between, Luna Rossa may have a tiny edge upwind, and Oracle may have a tiny edge downwind – and in this game a tiny edge can be used to apply pressure and make disproportionate gains, a bit like holding the T in squash, or getting to the net in tennis…

If there was a crux where Luna Rossa lost the match, it came when they let Oracle seperate out to the left halfway down the last run. Oracle were tight behind as the pair exited the top mark, but despite the pressure Luna Rossa matched Oracle's first gybe, and kept their air clear. Great defence. The next time Oracle tried it, Luna Rossa let them go, but not for long, and when they came back, the Italians had got a little gain. Perhaps emboldened by this breeze call and feeling the pressure because Oracle had been coming at them, at the next split Luna Rossa let Oracle get even further away. Not good defence. Oracle found a line of stronger breeze that the American's rode all the way past the Italians to the finish.

So, did the psychological pressure shift back to Luna Rossa in the final metres of today’s race? Not yet, but Luna Rossa have lost the chance to get a grip on the jugular. For Oracle to have gone 2-0 down - on the back of that loss to ETNZ in the last race of the round robin - would have been unsettling for the American team, to say the least. Now it’s even, and we start again from scratch.

There’s also been a lot of talk about the different tactical sailing styles, Torben (Grael/Luna Rossa) the magician sniffing the shifts and playing it loose, versus Terry (Hutchinson/ETNZ) trading distance for position and keeping it tight. I think there’s something in this, but it’s not the whole story. Right through the round robins we saw all the top teams play it really tight with the smaller teams – quite happy to trade tacks like punch drunk boxers until the only thing the headsail was good for was sailing bags (or shore-base construction in Luna Rossa’s case).

When the big teams know they are quicker and have better boat handling, they are happy to let those skills do the work, it’s more than enough advantage. But when they come up against each other, and there’s no more than the metaphorical fag paper between them, they have to dig deeper to find an edge. Where do they look for it? In their ability to read the breeze. The difference between the Luna Rossa v Oracle and ETNZ v Desafio racing is not so much one of style – we’ve seen Luna Rossa keep it tight with plenty of people – as a response to the opponent.

The other point worthy of note was Dickson’s aggression in going for the luff after Luna Rossa’s slam dunk tack at the top mark on the second beat. He’s caught Spithill like this before, and he obviously thought it was a worth another go. But it’s an all-or-nothing move – if you don’t get the penalty, and Dickson didn’t, you’re going to have to accelerate in all the bad air and waves of the other boat. Luna Rossa jumped back out to a two-length lead that they should have been able to hold on to…

Meanwhile, it was business as usual for Emirates Team New Zealand. Dean Barker and co. did a number on Desafio in the pre-start. This was all about the time back to the line, and Kevin Hall aboard ETNZ just had a much better idea than Matt Wachowicz, the navigator aboard Desafio. ETNZ chose to lead Desafio in the approach to the line, and never really needed to even look back. The Spanish were late and then got themselves under the layline for the committee boat. From there, they never looked like recovering. Terry Hutchinson, the ETNZ tactician, was happy to spend some of the 1m 15s delta they had at the top mark positioning his boat to keep the Spanish tucked away. The weekend is when Desafio’s supporters come out in force and they produce their best performances, but right now, it must seem a long way away…

The Revenge of the Westerly

Luna Rossa and ETNZ go one race up...

It was a big first day in the semi-finals for the Louis Vuitton Cup - Luna Rossa beat BMW Oracle by 2m 19s, and ETNZ went a race up against Desafio Espanol by 43s. But don’t let those finish deltas fool you – it was shiftier than a bloke selling 'second-hand' Rolex’s at a car boot sale, with the gradient wind blowing out of the west and off the city.

The first move came at the pre-start entry with Oracle coming in from the pin against Luna Rossa and crossing them on port. We’ve seen Oracle pull this one off half-a-dozen times (at least) in the two Round Robins, and they did it again – crossing ahead of Luna Rossa, the starboard tacker, who was entering at the committee boat. Once Oracle had got past them, they owned the right-hand side of the pre-start box and had negated the disadvantage of the port tack entry.

A huge amount of effort goes into the software used in the pre-start, but it’s easy to forget about the timing for the entry. All the work goes into modeling and predicting the boat’s approach to the start line through the different tactical maneuvers – the gybe or tack back, reaching down to the starboard tack layline for the pin, accelerating from downspeed to the line. The focus is on approaching the line, sailing upwind in the final seconds. And we’ve seen over and over how good the teams are at this, with perfect start after perfect start.

But the entry is different – the line you’re looking at is actually perpendicular to the start line, as it runs upwind from the pin. So a separate time-on-distance calculation should be done specifically for the entry, to account for the different angle of the line. The next problem is that the boat is reaching towards this line, rather than sailing upwind. This is the only time that you need to know the boat’s reaching speed, and so this job (sailing on a reach in all different wind speeds and angles so you can accurately model it for future performance) can slip to the bottom of the list and never get done.

It’s easy to end up with a fudged calculation for the entry, based on the wrong line, and using the wrong prediction of the boat’s speed. But not with Oracle, it looks like they've spent the time and money smartly, reached into a few more dark corners than everybody else, and nailed this problem. Whatever they've done, it works and they’ve practiced the entry enough to be really slick and confident. And it’s paying dividends. It was also clear that Oracle had accounted for the current that was running across the start line - although it looked like Luna Rossa could lock them out at the boat, in the end Oracle got a good start to the right, and separated well enough to live.

Then it got really tricky. There were some massive shifts coming through, tacticians and wind spotters on both boats having to back their judgment as it was a tough day to try and cover the opponent. Luna Rossa took a big lead up the beat, then lost it all on the run. And this was the crux of the match - the leeward gate. An aggressive move from Oracle, as Luna Rossa gybed to windward. With both boats now on starboard and laying the gate, Dickson put the bow up and luffed hard to hold Luna Rossa out past the port gybe layline, hoping to lead back and have the choice of gate mark.

But Luna Rossa managed to break the overlap, and once they had done that, Oracle had to come down to her proper course and gybe back towards the gate. Luna Rossa’s crew did a fantastic job of matching Oracle’s gybe, getting the headsail up and spinnaker down and holding their own overlap as they trailed Oracle back to the gate. It gave them room and control to take the left-hand mark, and that was the side of the beat that Torben Grael and Andy Horton on Luna Rossa wanted - it was the side that paid big-time up the next beat. Luna Rossa led comfortably round the final windward mark, and the big delta came from the sea breeze trying to fill at the end and dumping Oracle in a hole. Still, I wonder what odds you could have got beforehand on Oracle losing by a delta in excess of two minutes?

The other match was much more straight-forward, ETNZ won the right hand side in the pre-start, used it to get control and a good lead up the first beat and never really looked like losing it. So, Luna Rossa and ETNZ go one up in the best of five series, but there’s a long way still to go.

The Louis Vuitton Semi's Begin...

Don't worry if you've been out of the America's Cup loop since the end of the Round Robins - your quick catch-up is right here....

There were some dull press conferences - nothing like the good old days of the Dennis and Tom show at the AC in Fremantle.
‘Why would you want to build one [a Twelve Metre] in glass unless you wanted to cheat,’ says Conner.
Quick as the cars he loved to drive, Blackaller sticks in, ‘I don't think you can say that, Dennis.’
‘I take it all back," retorts Conner.
To which Blackaller drawls, ‘I don't think you can.’

Ah, happy days...

The guys at CupInfo.com have come up with a stats package for the first two round robins. They are using some pretty broad brush numbers – leg times, deltas and passes. So do they tell us anything about the boats? They ignore everything from sail selection to wind shifts to crewing errors – but we learned at OneWorld that these basic numbers often tell the same tale as a much more sophisticated analysis (with data unavailable to us spectators), provided you use enough races. Well, we have 22 races now - so, what do we know?

The stats show that you wanted a boat pitched at 8-9 knots for Round Robin 1, and 10-11 knots for Round Robin 2. Peter Lester's blog reckons that ETNZ was configured for 9-11 knots, which is the wind speed they came good in in Round Robin 2. So, maybe there’s something in it, unless Lester made his judgement from the CupInfo stats… But hey, that’s how this works, right – too many people jumping to too many conclusions with too little information?

So let’s get stuck in and make some more. Downwind, ETNZ appears to get better as the breeze gets up relative to all the semi-finalists, while Oracle gets weaker. Like Oracle, Desafio and Luna Rossa also appear more light air orientated, but not as heavily gear shifted to that end of the range. But across all conditions downwind, ETNZ appear to have a little jump on everyone, while there’s not much between Luna Rossa and Oracle, with Desafio a bit off the pace.

Looking at the upwind stats, ETNZ didn’t appear to have a weakness, while Oracle, Luna Rossa and Desafio all appeared to be moded for the lighter air. Overall, ETNZ again appeared to have the edge, with Luna Rossa next, Oracle not far behind and Desafio trailing.

The stats tell us that we’ll see ETNZ go 5-0 against Desafio, and Luna Rossa and Oracle will go all the way to the bottom of the ninth… Personally, I think it may come down to whether or not Oracle can improve their first cross record. After all those come-from-behind wins I wondered if this weakness would hurt them, and it did against ETNZ in that final race. Yes, Oracle have passed Luna Rossa once, but I doubt Jimmy Spithill and co. will be as accommodating across a five race series.

What changes will the teams have made between the end of the round robins and the start of the semis? The races start later and I think we can expect the sea breeze to be stronger and better developed, so if changes are made it will be to go from a light to medium air mode - and again, using those stats, we'd be more likely to see Oracle, Luna Rossa and Desafio making changes than ETNZ.

Then there are the defeated, the seven teams whose participation - as the man used to say - is no longer required. Shosholoza have already declared their intent to be at the August Grand Prix in Kiel. As have the Germans, but it’ll be without Jesper Bank, who resigned last week. ‘No one in our team is used to such a series of defeats,’ he said at the UITG press conference last Thursday. ‘That's why it has not been easy for us. I am not content with my performance. I don't want to stand in the way for the development of this German campaign. I would like to thank the whole team for its great work in the past two years and I am proud that I have been part of the first German campaign.’ And with that, the double gold medalist fell on his sword. Just kidding.

But just as interesting was the news that the Germans have now started construction of the second Version 5 boat that they’re allowed in this Cup cycle. It will give them a crucial extra asset should they continue. The decision to build the second yacht was apparently made regardless of whether United Internet continued with them or not – the money for it was already in place.

There was also an up-tempo interview from Stéphane Kandler, CEO, posted on the Areva website. They would obviously like to continue, and are going to do what GBR Challenge did at the end of the Auckland Cup, and finish their testing. But then, look what happened to GBR Challenge…

And finally, what of the Defender? Tim Jeffrey suggests Bertarelli might shut down the operation and take his toys away. It never pays to discount something like this when Tim puts it out there... but isn’t Bertarelli doing far too well out of this to stop? And on that note, another Pommie scribe, Stuart Alexander, reports that Bertarelli has just bought land alongside the likely Valencian Formula 1 street circuit that’s just been announced. And you can read that two ways - Bertarelli is swopping horses or leveraging his investment in the town...

But what about the story that CupinEurope.com found in La Libertad (now we're getting really seedy - stories from stories from stories...). Bertarelli apparently told Bernie Ecclestone, amongst others, that he was in favour of defending the next Cup in Valencia, should they hold onto it. He added that racing would take place every two years instead of four, with 2009 being set in Valencia and 2011 in Dubai, giving that country enough time to create the infrastructure necessary for such an undertaking. I say, enough already, let's go racing...

Reality Check

The first round of Louis Vuitton racing is over

Some random thoughts on what we’ve seen so far, in no particular order…

We’ve finally seen plenty of tight races, and that will help the Challenger cause. But I still think that this exercise has been more damaging than positive, too much nervous energy has been expended for too little. But if the weather stops draining the life out of the Challenger programmes, then constant racing at this level will give them an edge over the Defender.

Internal competition of the type that Alinghi are trying to simulate isn’t quite the same. The atmosphere is different when everything’s arranged by an outside agency. And worse, internal competition is divisive if taken too far and crew choice is left too late. Since the switch to the IACC class - with just one exception (1992) that I can think of - the Cup has been won by teams who have picked their race crews early and stuck by them.

Oracle have swopped boats since their rather average showing in Act 13 and gone straight to the top of the class. So perhaps Alinghi won’t turn up at the Cup with a speed edge that makes everything else irrelevant. But I still wouldn’t bet on it given their performance in Act 13, and the extra ten weeks they have for development while the Louis Vuitton is going on.

It looks to me like the top four have the destiny of the semi-final spots in their own hands. It’s theirs to lose - the chasing pack, Mascalzone, Victory and to a lesser extent Shosholoza, can only hope they do so… and keep trying to win their own matches.

I believe that only two teams posted new certificates after the overnight change period between round robins, UITG and China Team, so don’t expect anything radically new in the way of speed differentials. Having said that, new sails will be swopped into the inventory – some of those RR1 headsails have done a lot of tacks. Some of the replacement sails will have been ordered weeks ago, to fit in with production schedules, and sail coordinators will have been faced with the dilemma of tweaking the designs or leaving them the same. When those new sails arrive and get put up for the first time, those tweaks might not be all that was hoped for…

Winners

Oracle – Top of the leaderboard - ‘nuff said.

Luna Rossa – The predictions of a 2003-style chainsaw massacre after the losses to Shosholoza and Oracle have been shown up for what they were. This is a completely different team to 2003.

Desafio – Turned a shaky start with the loss against Areva into a solid fourth place and a semi-final spot.

Shosholoza – The soul of sailing took scalps and scared everyone, whatever happens from here they will go home heroes.

Losers

ETNZ – the pre-regatta favourites now languish in third, that handy aura of invincibility looking past its sell-by date. Now is the moment for them to show what they’re made of… as they say in cheesy B-movies.

The Rest

What else were you expecting?

ACM Squirming?

The Louis Vuitton Cup is struggling....

Bob Fisher has had another go at ACM (America's Cup Management) over their organisation of the Louis Vuitton Challenger trials. Bob quotes an unnamed ETNZ (Emirates Team New Zealand) crew member as saying they missed nine days of sailing in April last year, but a couple of days ago we had Paul Cayard quoting ETNZ weather man, Roger Badham, as saying this run of weather was one in a million. Make your minds up guys.

Unusual or not, it’s obvious that the lack of breeze is playing into the hands of the Defender. It’s not just about the amount of time and nervous energy being burnt going out to race every day with no result, while the Alinghi crew stroll round the golf course. It's also about the remaining schedule getting so compressed, that the opportunities for changing the boats become more limited (just 11 hours between RR1 and RR2) and the opportunity for development almost non-existent. Since all this appears to be happening because the date of the America’s Cup was set first and the Challenger trial dates then fixed as a consequence, it does appear that ACM have a case to answer.

But this is nothing new - in Auckland we started racing in the freezing gales of October and lost plenty of days. The Defender has the right to set the date of the Cup match, and the Challengers have to live with it – that’s how it’s always been. Maybe we were expecting something different this time... If so, I think it's because this is the first time the Challengers have tossed their hand in with the Defender and the whole thing has been run by one single management – ACM. Given that the Challenger group has handed over that responsibility, does it force a greater responsibility on ACM to ensure that the Challenger gets a decent chance? I think it does, and the fact that the playing field is now so steadily shifting towards Alinghi because of decisions made by ACM is going to become increasingly embarrassing - expect more broadsides from the mighty ‘Fish’.

Still, we shouldn’t forget that one of the primary reasons that we’re seeing teams like Shosholoza pressure teams like Oracle (or in Mascalzone's case actually beat ETNZ) is because of all the pre-Louis Vuitton racing in the Acts. And ACM were responsible for that. So it’s not all bad. But, the longer this exercise in futility goes on, the more the advantage amongst the challengers will swing to the big teams. They have the resources to better cope with the endless two race days that will become necessary to clear the schedule. And they will be desperate to keep the time gap between the end of round robin two and the semis, so they can rest people properly and do boat changes and minimise the impact of this schedule crash on the later matches. While the smaller teams will be desperate to extend the round robins - lots of action in non-smoky (these days) backrooms, I suspect...

Keels Again...

Keels are once again the hot topic in America's Cup medialand...

The non-deflecting-keel-gate rumbles on in the media surrounding the America’s Cup – although I’m not sure it’s to any great purpose. But keels have been a sensitive issue in the Cup ever since Alan Bond first covered his up in 1983, and then took the trophy home with a revolutionary winged keel. So I suppose it makes sense that now (with the new rules) the keels can’t be screened, the interest has shifted to the engineering inside the boats, which is still hidden.

Tim Jeffries chucked in his two cents worth in the Telegraph, where he comments, ‘What has been going [sic] is far more subtle and is a continuous thread of development through the last three or four Cups. Just as the sail designers know how advantageous it is to let the mast twist to match the curvature in the wind, so hull designers know that keel fins work much more effectively if some of the efficiency losses caused when they sag to leeward as the boat heels can be clawed back.

‘Precisely because the designers would love to make the mast and keel fin do things, the rules prevent them from using complex mechanisms to make this happen. What teams can do is use controls to limit or harness what happens when normal sailing forces are applied.

‘Any piece of smart, agile engineering that harnesses natural forces acting on the rig and fin keel is beneficial.

‘What is noticeable about the SUI 100 is that its keel fin shape varies over its four-metre depth. This suggests it will react differently as it 'flies' through the water. But Alinghi are not alone among teams in trying this idea.’

This is far from my area of expertise, but I thought the difference in fin shape from top to bottom was usually due to either weight optimisation – as the lower part of the fin carries less load – or down to varying the lift distribution over the fin. More lift at the root of the keel will be worse for wave drag, and more lift at the bottom will be worse for induced drag. The designers are playing these elements off to look for the most efficient solution. Using this shape to somehow alleviate the fin deflection sounds like the kind of free lunch that just doesn’t exist in sailboats.

Meanwhile, the NZ Herald is chasing the idea that… ‘Devices that move the keel are not permitted, but it is understood a number of teams have been looking at a way of linking the fin to the rig so that when the boat heels over, the pressure comes on the fin via the rig, which may reduce the deflection on the keel.’

This sounds like some seriously complex, and therefore, heavy, engineering, particularly as the rig loads enter the hull in a different place to the keel loads – and surely they’d have to line up, otherwise you’d be twisting the keel, not stiffening it? On balance, I’m still inclined to think that this whole thing blowing up at the start of the Louis Vuitton, and in an NZ newspaper, was too much of a coincidence - someone is just trying to pull our chains. Fortunately, with no racing for a couple of days and not much else to talk about than which supermodel Oracle have on the back of the boat, we’ve got plenty of time for such diversions…

Keel-gate or Not...

Canting-keel-gate by another name...

One day into the Louis Vuitton Challenger Series, and already we have a controversey - surprised? But canting-keel-gate looks like it’s turning out to be non-deflecting-keel-gate, which isn’t quite as catchy. Sail-world have kindly posted the relevant rule and the interpretation that was requested (which started it all). While Bob Fisher’s take on it is here. But as the man at Valencia Sailing points out, the interpretation has been kicking around for ten months, and it surfaces right at the start of the LV?

Still, to back up a bit, the advantage of a canting keel, as used in the Volvo Ocean 70, is to drag the lead bulb on the end of the keel fin, up to windward and so increase the righting moment. This involves a lot of engineering to allow the whole fin to rotate, not to mention the hydraulics to pump it from side to side when you tack. And according to the interpretation, it looks as though Ken McAlpine, the Technical Director for the yachts, has stymied any possible investigation of a loophole here – as he should. But there might be scope in the answer for just limiting the amount the keel fin normally deflects to leeward.

We used to have a ‘keel cam’ on the OneWorld Challenge boats. It was there to check for weed, you could view it from a browser window on the on-deck computer screen. But when those long testing days were getting to you, it was always entertaining to watch twenty tonnes of bulb flapping around on the end of the steel fin - more interesting than Coronation Street anyway. Particularly when you're sitting on the boat - the point is that the fin bends a lot, and the bulb moves a long way to leeward. If this can be prevented there is a big gain to be made in righting moment and speed. But you’d need someone a lot smarter than me to work out how to do it without contravening either the rule, or Ken’s interpretation.

Challenger Trials…

Louis Vuitton Cup Round Robin One Gets Underway

So from here it’s all going to happen very quickly and a lot of people are going to be headed home from the America's Cup in Valencia very soon. The boat announcements make the news this weekend - with both Oracle and ETNZ dumping their Act 13 rides.

In a recent Seahorse interview, Marcelino Botin reckoned the two ETNZ boats were designed for different wind ranges and this might be a clue as to why they’ve switched. It’s conceivable that 83 was developed as more of an all-rounder for the Acts, with the second boat focussed on winning the semis and finals in Valencia’s sea breeze. Act 13 was hit by an unstable weather pattern, and the all-rounder was probably the better choice. Perhaps that unstable weather is now reckoned to be behind us as we move into the more predictable summer sea breeze (if it ever stops raining) – and be more to 92’s liking?

As for Oracle, the same might apply as for ETNZ… but USA 87 put in a less than world crushing performance in Act 13. And when Oracle has been deep in the dodo before, radical change did work for them - a decidedly dodgy opening to the Louis Vuitton in 2003 saw the axe wielded ruthlessly by Larry Ellison and the previously side-lined Chris Dickson brought back to centre stage. On that occasion, Oracle recovered to appear in the Louis Vuitton Cup final against Alinghi. The first few races of round robin one will tell us whether this boat switch will do the same trick.

Everyone else has stayed in the boats they used in Act 13. The very first flight has the real winners of Act 13 - Mascalzone, fast improving runners up to ETNZ – up against the team that only beat them by a point. This match will begin to tell us whether ETNZ can continue to dominate the challenger fleet and whether Mascalzone are genuine contenders for the semis – are we watching a prelude to the semi-final match-up?

The Final Act

Louis Vuitton Act 13 ends with a comprehensive win for the America's Cup defender

All right, I know that headline is probably being used in a dozen different places to open reports on Louis Vuitton Act 13 - the last regatta in the series of preliminary events ahead of the Louis Vuitton Cup. But the coincidence of that and a comprehensive fourteen point win by America’s Cup defender Alinghi does raise the question – is it all over before it’s begun?

I asked a couple of people (who should know) before the start of Act 13 if they thought that Alinghi was likely to turn up and race with their optimal configuration of hull, foils, bulb, mast and sails – and the answer was no. It was hard to see what they might gain from showing their hand to the Challenger fleet so early. After all, only Alinghi know where the boat they used in Act 13 sits, in performance terms, relative to what else they have in that vast Valencian operations base. They could use a slower configuration and still get a measure of the challenger fleet, without revealing the full extent of their own performance gains over the winter.

Or – alternatively - they could come out fully cocked, hoping to blow the doors off everyone else and achieve a psychological victory that would still be echoing in ten weeks time.

Let’s hope it’s the latter, because if Alinghi have more speed to come, then the America's Cup match will be another whitewash. If there’s one clue that they might have chosen to race with their fastest gear, it dates back to 2003, when they sailed against OneWorld Challenge before the opening Louis Vuitton Round Robin. They thrashed us comprehensively with the new boat (although rumours were circulating that it didn’t measure), and then brought the old one out for the Round Robin - only to end up with us taking a race off them and topping the group.

Afterwards, there were stories that the result had shaken their confidence more than a little (fully restored by reversing the result in Round Robin Two and leading the challenger fleet from then on…), but the memory of that experience may have been enough to convince them that winning counts for more than guarding their hand.

But even so, back in 2003, Alinghi’s quicker pace of development during the Louis Vuitton Cup won them the challenger title. They managed that despite the distraction of racing, but this time the LV schedule is much tighter, making it difficult to see where the challengers are going to find the time to make gains in pure boat speed - rather than racing competence. They will be busy keeping the tills of Valencia ker-chinging by providing the entertainment for the next two and a half months, while Alinghi will be quietly doing more of what they’ve already established they are very good at – producing phenomenally fast boats.

Looked at like this, it’s hard to see why this wasn’t the final act….?

A Trip to Valencia

Esquire Photo Shoot

I've just come back from Valencia, doing some interviews for Esquire magazine - they'll accompany a photoshoot that will appear in the July issue. It was interesting to go round nine of the twelve team bases and see how they respond to a gaggle of photographer, assistant, journo, stylist and make-up all arriving en masse.

(Photo - the America's Cup Harbour before the circus came to town)

In some we had to work out how to make our own coffee, while waiting 45 minutes for the interviewee to arrive, in others we were treated to espresso, cake, and a spot in the sun on the balcony while we waited our turn to do our thing - take the picture or quiz the victim. If the facilities offered are any indication of the race course results (and three races into Act 13 there looks to be a reasonable correlation) then the fourth semi-final spot is between Mascalzone and Desafio Espanol, the Challenger spot is too close to call (although Emirates Team New Zealand was one of the bases we didn't visit) and Alinghi will win the Cup!

The interviews went better than I thought, some people are more thoughtful or more forthcoming than others, but the general standard was way above the 'game of two halves' football cliché. Let's hope the clarity and honesty continues when the pressure's on...
