CHICAGO MATCH CUP BRINGS AMERICA’S CUP AND OLYMPIC-STYLE COMPETITION
TO CHICAGO

11 teams entered from 5 continents in the highest-graded international
event to date

CHICAGO, August 17, 2009 — This week 11 teams from Australia, New Zealand, Japan, Argentina, Denmark, the US Virgin Islands and the USA will start three days of competition for the inaugural edition of the Chicago Match Cup, held over August 21-23. Organized by the Chicago Match Race Center (CMRC), this International Sailing Federation Grade 2 event will be the most international sailing event held this year in Lake Michigan, bringing one-on-one America’s Cup and Olympic-style match race sailing to Lake Michigan.

Pitting the skills of one team against another, match race sailing is one of the most intense forms of sailing and is used in the America’s Cup, World Match Racing Tour, and most recently as a new Women’s discipline in the Olympic Games. The short courses, umpired rules, and one-on-one format is also ideal for spectators to follow all the action.

“This is regarded as a peak event for us,” says CMRC Director Bill
Hardesty, “because we’ll have some very high caliber international
match race talent here to do battle. For spectators and sponsors alike
this is a unique opportunity to see some truly world-class match race
sailing being put on right here in Chicago.”

11 International teams
Skippers entered in the Chicago Match Cup include the following:
Taylor Canfield, from St Thomas, USVI; Reuben Corbett, from Kerlkerl,
New Zealand; Juan Grimaldi, from Mar del Plata, Argentina; Laurie
Jury, from Auckland, New Zealand; Takumi Nakamura, from Yokohama,
Japan; Lars Nordbjerg, from Aabenraa, Denmark; Dave Perry, from
Southport, Connecticut USA; Phil Robertson, from Auckland, New
Zealand; Keith Swinton, from Perth, Western Australia; Chris VanTol,
from Grosse Pointe Park, Michigan, USA; and Don Wilson from Chicago USA.

TP52 – Audi MedCup – Portimao

Paul Cayard
Friday, August 21, 2009

Another good day on the Artemis today! We got the bullet and moved into first overall for this regatta.

That is two “coastal” race wins in a row for Artemis now with this one and the win in Cagliari. They are nice to win because they count 1.5 times a normal race.

We had an ok start and went left for quite a while. It looked like there was more pressure to the left but we are always weary of the right shift upwind here. We got around the top mark 6th just barely but then got rolled by Bigamist right away. So that was our low point.

>From there we battled back, first going all the way offshore on that first run to round the first gate 3rd. Matador had a nice lead and Audi Q8 was second. We held third up the second beat and onto a 120 degree reach. Team New Zealand was right behind us in fourth.

Up the third beat, Team New Zealand passed us by getting to our left. We rounded the third windward mark 4th but once again, we went the hardest offshore. We passed Audi Q8 and closed up all the distance on Matador and Team NZ.

Then the angle was up 20 degrees for 7 miles and they went with the Masthead Jib’s while we peeled to our A3 gennaker. We smoked through them to leeward and just hiked our butts off to blow through into first and make the mark. From there we just controlled Team New Zealand up the final 4 mile beat to the finish.

Obviously we are very happy with how things are going but we know this regatta is far from over. 4 races to go over the next two days and for sure we can expect less friendly tactics from our competitors.

I am leaving tomorrow night after racing as I had a previous commitment to race the 505 worlds. So Hamish Pepper, 2006 Star World Champion, and currently our strategist, will take over as tactician for Sunday. I will miss the last day of this regatta and the first day of the 505 worlds while flying home to SF.

Weather for the Coastal Race

Portugal Trophy

Coastal race day for the TP52′s and the weather forecast has a very similar look to yesterday.

The thermal breeze will kill off most of the early northerly gradient again before the race start time of 1300hrs. The problem, such as it is, will be that around that time the westerly component will just be starting to drag the breeze back to the right, and so the chances are that there will be a delay to the starts for both classes, possibly around one hour. That it is this morning’s theory but the plan is certainly until the wind is more settled.

During the afternoon the breeze will then pick up more quickly and there could even be a little bit more breeze than yesterday, up to 20 knots.
The course distance is expected to be around 27 miles following the usual format with a windward-leeward loop to start then a long reach out to an offshore mark at Piedad, then a beat back in to the west corner of the bay at Lagos, run or broad reach back out to Piedade, long reach to a variable mark and then a final beat or close reach back in to the finish which will be in the river Arade, just short of the entrance to the Marina of Portimao.

Last year’s coastal race was lost to the lack of breeze, but in 2007 the wind was very split and it proved a very complex race with big splits developing after the top mark in the Lagos Bay. The pressure differential was much more than we have seen in the past two days in that area, so other than the start and first beat, these long runs could be decisive today.

Meantime the GP42 Series will contest probably two windward-leeward races.

Open minded and on top

AudiMedCup_m2339_090821rw_4703

A polished performance from Paul Cayard and the crew of Artemis won them their second consecutive coastal race and promotes them to the top of the overall leaderboard of the TP52 Series at the Portugal Trophy off Portimao.

Cayard attributes some of their success to date at this regatta to always remaining open minded about this venue, not bowing to preconceptions set from two previous TP52 MedCup events off this Algarve resort.

Artemis lead the Portugal Trophy regatta by 1.5 points going into the final weekend, though they are mindful that they had a bad final day at the Region of Sardinia Trophy which sank their chances of winning the regatta, but Cayard says they will take no special precautions or lessons from Cagliari into the last two days of racing here:

“We what it was there was down to a matter of metres.” Cayard re-affirms, “ Every time we came into the top mark we were three metres away from being able to tack under someone and get round the mark in third and instead we were ducking three or four boats. That is how close this fleet is. Often on the first beat it is a matter of metres. That’s what got us these sevenths and eighths and then we had a problem with the pumping penalty and fouled someone, so on the last day we did just about everything wrong on that last day.”

“I think, though, if you look at the overall picture over the two regattas we have had eight days of sailing and we have had seven very good ones. And so, as a team, we are building a lot of consistency and strength and so we just stay focussed.”

There 27 mile, eight leg course, up to the west of Portimao to a turning mark under the cliffs at the Pointe de Piedade followed by a long run and reach down to turn for home at the equally commanding Praia Carvoeira cliffs, just to the east of Portimao’s Arade river.

The finish line, half a mile up the narrow river off the Marina of Portimao, saw Artemis coast across the line in the evening sunshine to the delight of a large spectator fleet and the hundreds of holidaymakers on the adjacent beaches.

The race followed a strangely similar plot line to Cagliari.
Once more Matador (ARG) lead early on but made the wrong sail choice, as did Emirates Team New Zealand, both separating a little too high from Artemis (SWE) on the long reach down the outside of the bay.

Cayard and crew were always able to capitalise – despite racing without wind instruments – regularly rewarded for their persistence as they climbed from seventh at the first turning mark to take the winning gun, with ETNZ, also second, just as they were in Cagliari.

“We are just having a good regatta. We are sailing really open minded. There are a lot of preconceptions about this venue for a lot of us who have sailed here the past two times. It’s been a very different venue to the past two times, so we have capitalised a lot on doing things that aren’t ‘normal’ for here. We are leaders by one inch, and Team New Zealand are going to be tough.” Cayard concluded.

Caser-Endesa’s Day in the GP42 Series

In the GP42’s being consistent and error-free reaped huge rewards, as the Caser-Endesa (ESP) team demonstrated with their impressive 2-1 score today. With the breeze a little more varied in strength, those who could choose their paths for clear air and pressure upwind and down would win in the numerous chess games played in this tight class.

Race 1 saw Roma 2 (ITA), skippered by Paolo Cian (ITA), leading nearly all the way around the track having benefited by finding slightly more pressure early and defending their lead. But Endesa, helmed by Juan Luiz Paez (ESP), was pushing them hard the whole time, even briefly managing to round inside and ahead at the bottom gate.

With a slight drop in pressure in Race 2, it was Endesa this time taking and defending an early lead, despite furious attacks made by Roma (ITA) and even Airis (ITA), driven by Cameron Appleton (NZL), who got right into the action for the first time in the Series. However, the fight was always on for the second through fourth places on the runs, as numerous tactical attacks and lanes of pressure kept re-shuffling the order amongst Airis, Roma, and even Turismo Madrid (ESP), driven by Jose Maria van der Ploeg.

Even in the final 100 meters of this race the order changed twice, with Madrid just able to squeeze ahead of Airis by 3 seconds, Roma by 10 seconds, and Islas Canarias Puerto Calero (ESP) by 13 seconds.

These results have had profound effects on not just the regatta standings, with Endesa now in the lead by 1 point, but in the overall standings as well, with Puerto Calero now overtaken by Roma also by just a point.

Quotes of the day:

Guilermo Parada (ARG) skipper-helm Matador (ARG):
“ We’ve been first till the fifth mark and then we had two sail choices and we chose the one we thought was better. Emirates were behind us and they chose the same as us so every thing was ok. But Artemis chose the other one and it payed off. Artemis passed us and when we changed from one sail to the other. Emirates made a better change and passed us. That’s what happened. We thought the wind was going to shift to one side, and it went to the other way.”

Ray Davies (NZL), tactician Emirates Team New Zealand (NZL):
“ On the reach Matador and us chose to go to code zeros and Artemis went for the H3 (reaching gennaker) and they got separation and they were a little bit faster with that. We and matador hold on but Matador rounded in the outside of us so that’s where things changed.”

Juan Luiz Paez (ESP) helm Caser -Endesa (ESP):
“It’s been a very positive day for us but there’s still a lot of work to do. There are four races left out of the nine scheduled, but we are still happy because we feel stronger every time, especially if you compare us to how we started the season in Alicante.”

Put it in Your Diary!

Next weekend Mike Perham will arrive home.

From his blog

After last night’s racing, things have slowed up quite a bit today as the wind dropped off to around 15knots, but this won’t last long as tonight it’s going to pick up once again. The small low pressure I was riding yesterday has now moved along and we’re now really hooking up into what Mike Broughton, my weather router, has aptly called the ‘Bad Boy Low’. This is going to give me solid wind for the next five days or so as it moves across the Atlantic to Ireland where it will stall.

It looks like a real whopper but the wind strengths are totally manageable and shouldn’t fall to the wrong side of 40knots. The good thing is that this system will provide me with great predictable winds, which should speed me homewards.

It’s been really nippy today and I really felt the cold earlier as I went outside for a little too-refreshing bucket over the head shower. It was still well worth it despite the rather mixed feelings I felt the moment the freezing water poured over my head!

I’ve been on the phone a lot more in the last few days, doing quite a few interviews and live radio link ups, which has been good fun as always. Earlier I was on the phone to one of my best mates and it was really great to have a good catch up and talk about loads of different stuff. It’s a little weird to think I’m only eight days away now when I’ve been away for so long and haven’t seen my friends for ages. I’m dead excited to catch up with them though. I’ve lots of stories to tell!

Hilary is nearly home too :-)

tmpphpdcFnSL

Kent sailor Hilary Lister’s challenge to be the first disabled woman to sail solo around the British Isles is expected to be completed with a celebratory welcome as she arrives at Dover harbour on September 1 after three months at sea.

We had a quick trip down to the mouth of the Humber. The wind dropped off for a while, but we still managed an average of over 5 kn for the whole trip. The Humber at night is an incredible array of lights. It’s incredibly busy after miles of seaway where we have seen little. We had to wait for a pilot boat with two coasters following before being given permission from to cross the Traffic Separation Scheme. Once given, it was a race across and (of course) the wind chose just that moment to drop off a little! We were soon safely across and heading up the Haile Channel into the Humber itself. Once in, the traffic quickly drops away again and it was earie going into Number 2 Fish Dock at 2:30 AM.

Colin Dean, a Lion, was there to greet us along with the shore crew. He and his wife Doreen had been entertaining them in the bar until about 10 PM when he had gone home for a few hours sleep. The crew had done their usual great job at setting everything up so that we could just roll into bed. Humber Cruising Association Club has just been refurbished, so facilities for me were great. You know that life has changed when you find a disabled loo that is the right height and are overjoyed to see it!

We had a very busy day’s “rest”. I managed to grab a couple of hours in the afternoon in between various interviews and then the whole crew attended a reception the Lions put on. I was absolutely overwhelmed at the turnout. I think they were members of every club in the district represented as well as District Governors past and present. Not only had every club given us money, but they passed a bucket round at the end of the night and collected even more. As people who had already put their hands in their pockets once as Lions they were also incredibly personally generous.

Please note: Hilary is now expected to arrive at Dover Harbour at around 9am on September 1.

AlinghiD35_cb_0146

Ernesto Bertarelli and his crew return to Lake Geneva this weekend for the two day Open de Nyon regatta. After the summer break, the 11-strong fleet of Décision 35s will meet on the start line in Nyon for this weekend’s competition; the sixth in the Challenge Julius Baer championship.

Alinghi.com spoke to Pierre-Yves Jorand, mainsail trimmer onboard Alinghi SUI1, about what to expect from this regatta and to find out what they have learned from sailing Alinghi 5, the Defender’s giant catamaran, since they began on 20 July.

We are entering the final stages of the Challenge Julius Baer, the Décision 35 championship on lake Geneva, what are the objectives of the team?

“We want to maintain our leading position. It’s going to be tight as we only have one point lead on Alain Gautier on Foncia and Loïck Peyron on Okalys. We are looking forward to great racing this weekend in Nyon. The weather forecast is looking pretty good: Northeast of around 10 knots for Saturday so we expect to have very exciting racing.”

You have training for the last few weeks on a big multihull such as Alinghi 5, and now you go back to a much smaller one, a D35, can you tell us what the differences are and also what you have from the training period on Alinghi 5 so far?

“Obviously the load differences between these two boats are huge, that’s the main difference. The D35 has always been a great practice platform, it’s a fantastic boat also for lake conditions, they are overpowered boats and we are really looking forward to going back to training and racing on it. On Alinghi 5 we are on a learning process. We were very focused on practicing carefully and cautiously during the first days of sailing, learning about the systems, looking at the platform, the loads, etc, while on the D35 we are very much race oriented so in this week’s practice we’ve been focusing on the pre-starts, the timing and the crew work.”

Class 40 World Championship 2009 Day 3 – Round the Island Race

Day 3 and the sunshine and light breezes had moved over to allow for a proper British south westerly cold front, complete with cloud and rain to propel the Class 40 competitors around the Isle of Wight.

The race started at 0900hrs at Universal Marina buoy with 15 – 18 knots of breeze from the the southwest, giving them a beat to the needles as the fleet headed off on the traditional anti-clockwise course around the island. Tanguy de Lamotte’s Initiative Saveurs – Novedia Group and Arnaud Aubry’s Courrier de L’Odet were forced to retire early due to damage sustained in a collision during the start.

By midday the fleet was already around the needles and screaming off downwind towards St Catherines Point, propelled by squally gusts of up to 30knots. Not only are the points weighted for the race, competitors were also in the running to win a bean bag specifically designed for offshore racing and donated by Amanda Russell at Pigbags.

Felipe Cubillos onboard Desafio Cabo de Hornos was the first to round the Bridge Buoy and set off down the back of the island towards St. Catherines point, closely followed by Tony Lawson’s Concise. Lawson’s team managed to take the lead downwind and maintain it until the finish.

A new modification to team BMW ORACLE’S trimaran….an addition of an aerodynamic wing attachment to the rear beam. If you look close (click on images to enlarge) you can see the white triangle shaped attachment to the beam. It is covered with telltales to show wind flow. We do not think this is where the engine will go. We think that is a test to see if they can reduce drag coming off the rear beam.

New Lawyers Will Make AC33 “The Greatest Event Ever in the History of Sailing.”

a-alinghi-cartoon

A penchant for crusading litigation? Cartoon from Alinghi.com

For those of you who haven’t ever seen the Alinghi ‘cartoons’ you are missing one of the quirkiest communications gimicks of any America’s Cup team ever. Often completely baffling to an outsider, these little PR missiles are a reminder of the difference between the Swiss and American teams. This week’s cartoon refers to a reported incident in which a BMW ORACLE Rib allegedly had a close call with a local fisherman while “spying” on the Alinghi sea trials.

Normally such a thing would be thrown on the ever mounting pile of irrelevency surrounding the 33rd Edition of the once glorious event, but new reports suggest that the GGYC’s thirst for litigation is far from quenched. Several sources have reported that David Boies, once retained by Emirates Team New Zealand, has joined the Golden Gate YC legal team.

Tom Ehman, fresh from acting as happy shiny master of ceremonies at the BMW ORACLE ’special event’ in San Diego is back to his ‘worst rules in history’ speech saying:

There continue to be serious issues with the way Société Nautique de Genève is conducting their stewardship as Trustee of the oldest trophy in sports, and the way Alinghi have mounted their defense of the America’s Cup – from Day 1 when they tried to issue rules that were widely condemned as ‘the worst … in the history of the America’s Cup’ to their recent issuance of measurement regulations that would disqualify our boat if left to stand.

Of course BMW ORACLE and GGYC are not out for themselves. This is a much higher calling, the reputation of the cup and the whole sport of sailing is at risk if the legal crusaders fail. Ehman continues

Nice Friday morning start

The teams gave the best of themselves in a very intense start of leg 7 this morning off Norra Stavsudda. A southerly 10 knots breeze helped the show. It was clear that the overall leaders wanted to start strong with just two days to go. Citus did the best start in the right side of the line, while in the pin side it was the German team W4 who got the best spot.
Thule passed in front of the bow of half the fleet right over the line. The wind picked up slowly afterwards to some 16 knots. Citus held their lead in the three first checkpoints, but followed very closely by Thule. The Swedish are far from giving up!
So far 2 teams have retired from the leg due to different problems and are sailing straight to the finish in Grinda. They are Ursuit and SWE 49.

Archipelago Raid – topptrion drar ifrån

STOCKHOLM 20 augusti 2009 – Efter fyra dagar av totalt sex är det tre team som har ryckt ifrån i toppen av Archipelago Raid. Franska Team Citus leder före brittiska Team Audio Network. Bakom dem jagar svenska Thule med svenske mästaren Martin Strandberg och Johan Örtendahl.

– Fransmännen är tuffa motståndare. Vi hade inte det sista som behövdes för att slå dem idag, säger Martin Strandberg.

Det fortsätter att blåsa rejält i Stockholms skärgård och torsdagens två etapper av Archipelago Raid bjöd på flera tillbud. Många båtar kapsejsade, men ingen gav upp. Samtidigt visade Stockholms skärgård upp sitt allra bästa ansikte med strålande sol och varma sydliga vindar – även om de var starka. Och mer lär det bli.

– Men vi hoppas på lättare vindar. Vi hade det för några dagar sedan och då var vi snabbare än fransmännen, säger Strandberg.

Tyvärr lär hans önskan inte slå in. Åtminstone inte om väderprognosen håller. Där talas det om sydliga vindar mellan 12 och 15 sekundmeter. Det betyder kuling.

Båtarna lämnade Mariehamn på Åland på torsdagsmorgonen för att segla en etapp över till norra Arholma. Dagens andra etapp gick söderut till Norra Stavsudda, via Rödlöga.

Fransmännen, som vann Archipelago Raid förra året, fortsätter att visa att de behärskar skärgårdssegling genom att bli tvåa på dagens första etapp och etta på den andra. Vinner de i år igen blir de tillsammans med svenske Magnus Woxén de enda som vunnit tävlingen två gånger.

Men britterna på Team Audio Network och det svenska teamet på Thule är också med och hugger i toppen av det 25 båtar starka fältet. På torsdagen blev de trea och fyra. På fredagen är det kappsegling i Stockholms skärgård som gäller innan båtarna når etappmålet Sandhamn och på lördagen går de i mål på Lidingö utanför Stockholm.

Race Orange Cat across the Atlantic ahead of Bill on line now

I asked Brainaid a few questions about how he plays his SOL and his sail planning,

here is a sample;

Do you steer the boat by hand or does your software have full control?

As said above, I often steer by hand, almost always during tricky
manoeuvre and when running somewhere between my suggested route and
optimum VMC. In the latter case this is often some close combat boat
against boat for a single place in the ranking. During open ocean
crossings I often calculate DCs from my software and use these.
There is no direct link from my software to the boat, so all of this
is checked and verified by myself and then set on the boat.

Highest Ever Winter Water Temperatures Recorded Off Tasmania

090807103907-large
NOAA polar orbiting satellites obtain the data generating sea surface temperature images. This is a composite 15-day image showing the extension of the Leeuwin Current around Tasmania. (Credit: CSIRO)

ScienceDaily (Aug. 20, 2009) — Tasmania’s east coast is recording its highest-ever winter water temperatures of more than 13ºC – up to 1.5ºC above normal – due to a strengthening of an ocean current originating north of Australia.

Satellites have given oceanographers an insight into a remarkable phenomenon – a significant extension of the Leeuwin Current curling around the southern tip of Tasmania and reaching as far north as St Helens.

Remote sensing specialists at CSIRO’s Wealth from Oceans Flagship have been observing the current in recent days using satellite data, and ocean measurements made near Maria Island on Tasmania’s east coast.

CSIRO oceanographers Katy Hill, David Griffin and George Cresswell study ocean behaviour in the Australian region. Dr Cresswell says that scientists use ocean observations from satellite, ocean instruments and research vessels – such as the Marine National Facility, RV Southern Surveyor – to track the currents but there are also other indicators such as tropical species reaching Tasmania.

“It’s important for us to monitor these changes in the ocean, as they can have consequences for marine ecosystems, fisheries, aquaculture, coastal communities and more,” Dr Cresswell says.

The Leeuwin Current forms north of Australia and flows right around the western half of the country, meeting its better known cousin, the East Australian Current (EAC), at Tasmania. The exact location of this meeting point varies both seasonally and from year-to-year, depending on how strongly each current is flowing.

Oceanographers believe the EAC has gradually been getting stronger, and the Leeuwin Current weaker. Changes in the EAC are among the most significant in the global ocean, with a continuous record of monthly measurements one of Australian oceanography’s most valuable indicators for climate and environmental monitoring.
