NO MORE LEEWAY

New navigation capability to PUMA Ocean Racing Team

— filed under: 

Nortek announced today that it has collaborated with the PUMA Ocean Racing team to develop a modified compact Doppler Velocity Log (DVL) for PUMA’s Mar Mostro Volvo Open 70 yacht competing in the Volvo Ocean Race 2011-2012. The project, which was completed over the course of the past year, has resulted in the successful integration of boat speed, leeway and in-situ ocean current readings. Translation: a secret weapon in the battle to go as fast and efficiently as possible.

The message below is the full press release from Nortek and the PUMA Ocean Racing Team — for questions or comments, please chime in on theNortek Facebook page.

“The collaboration between Nortek and the entire PUMA team has resulted in an tool that provides unique information to the sailing crew.  They can now measure leeway, a first in sailing, and use it to measure ocean currents much more precisely than ever before,” said Atle Lohrmann, CTO of Nortek.

Nortek started developing this capability during the 2008 Star class Olympic trials with the Norwegian team skippered by Eivind Melleby, also a veteran of the Volvo Ocean Race. Nortek went on to work with the TP52 ocean racing team Caixa Galicia with a predecessor to the existing sensor with Caixa navigator Robert Hopkins.

“This is the biggest advancement in sailing instrumentation since the invention of the GPS,” said Hopkins, who runs performance testing for PUMA and worked with Nortek on the project. “Nortek adapted their new DVL technology to our sailing performance needs, to measure very high speeds along the boat’s track and very low speeds across it. With Nortek’s history of deploying instruments on buoys in hostile Arctic conditions, we knew that we could trust the Nortek DVL in a race around the world.”

Leeway is the sideways skidding angle a boat makes as it sails forward. Leeway can be changed on a Volvo Open 70 yacht by adjusting the daggerboard immersion and canting the keel. The adjustable daggeboards and keel act like wings underwater to counteract the force of the sails. The crew relies on Nortek DVL leeway measurements to optimize PUMA’sMar Mostro performance at all times, providing the core data upon which every other performance measurement is based.“I can’t tell you how important it is to finally know how fast the boat is going in all conditions. We really feel this is the first time boat speed has been accurately measured without using various types of cumbersome and complex tables within the boat’s instrumentation. It’s a huge factor for something as simple as a sail change or as complex as routing,” said Ken Read, skipper of the PUMA Ocean Racing team. “Nortek and our entire team, especially the shore crew, worked diligently to make this project a reality. The technology already helped us to win the Transatlantic Race in July, and it will be a key component as we race around the world.”

The Nortek DVL uses acoustic techniques to measure water velocity along each of the four beams.  The sensor is mounted in the bottom of the lead bulb of the keel. The acoustic beams are oriented forward, aft and abeam.  Data from each beam is streamed to the on board computer which also receives data from the inertial motion sensor and the keel cant angle sensor. Velocity and orientation measurements are then used to output true forward boat speed and leeway. Real time currents can be directly estimated by differencing the GPS boat speed over ground and the boat speed through the water.

Similar systems were developed for the seismic survey fleet and Nortek recently delivered the first operational navigation system to Fugro-Geoteam in Oslo to be mounted on two Barovane seismic diverters.  The diverters keep the towed acoustic streamers separated and like the Puma-DVL, the system measures the angle of attack, the through water speed and ocean currents near the surface.  The difference was the space available for the acoustic transponder.  “We worked very hard to miniaturize the DVL unit that was installed aboard PUMA’s Mar Mostro,” stated Lohrmann.

The project is an important milestone for Nortek because it demonstrates how well the acoustic Doppler technology performs in very challenging conditions and that the system can be fully integrated into modern navigation systems. The fact that the PUMA Ocean Racing technology team was able to integrate the DVL with other sensors on the boat is a testament to the quality and sophistication of modern yacht racing.

The PUMA Ocean Racing team sets out on the first leg of the Volvo Ocean Race 2011-2012 on Saturday, November 5, departing Alicante, Spain, for Cape Town, South Africa. The 11-member crew will travel 39,000 nautical miles over nine months, sailing from Alicante to Cape Town, and on to Abu Dhabi, UAE; Sanya, China; Auckland, New Zealand; around Cape Horn to Itajaí, Brazil; to Miami, Florida, USA; Lisbon, Portugal; Lorient, France, finishing in Galway, Ireland in July 2012.

NEWPORT, BE CAREFUL WHAT YOU WISH FOR

Here is the diagram of the America’s Cup course for the upcoming San Diego series. It will shut down the port entirely during the event. Granted it is only for a few hours each day and only the days of the event. But no other boats will be moving. In San Francisco it will shut down the commercial port and all commercial traffic.

In Newport, next June it will be no different. For anyone not consumed by the America’s Cup, it is liable to be a nightmare.

LUNA ROSSA IS IN

Finally, there will be some style and likely good parties, good food as part of the America’s Cup. In sharp contrast, the freeze dried food is being loaded on the  6 Volvo 70’s which leave on the sixth for the first leg of the round the world race.

The team Luna Rossa was established in 1997 by Patrizio Bertelli with the original name of “Prada Challenge for the America’s Cup 2000”. At its first attempt the team wins the Louis Vuitton Cup – the challengers’ selection series – in 2000, with a record of 38 victories over 49 races. Luna Rossa has participated also in 2003 and in 2007 it reached the Louis Vuitton Cup final. Luna Rossa is currently participating in the Extreme Sailing Series, the Extreme 40’ catamarans circuit, where it is leading the overall standings.

Emirates Team New Zealand is the current holder of the Louis Vuitton Cup and is leading the America’s Cup World Series. Established in 1985 as the New Zealand Challenge, Emirates Team New Zealand has won both the America’s Cup twice and the Louis Vuitton Cup twice. It also participates in the Audi Med Cup and Extreme Sailing Series international racing circuits and will be at the start of the 2011/2012 Volvo Ocean Race with the yacht CAMPER.

The Circolo della Vela Sicilia, founded in 1933, is one of the oldest and most prestigious yacht clubs of the Mediterranean. Its club house is in Mondello, a few kilometres from the centre of Palermo. Throughout the years the Circolo della Vela Sicilia hosted many prestigious national and international regattas, including the J 24 and Star Class European Championships, the Italian Olympic classes Championship and the “Palermo – Monte Carlo” offshore race.

KIM KARDASHIAN IS GETTING DIVORCED

I am troubled that I am even am aware of this news. I am troubled that it is considered news. The world is in flux. There are serious decisions to be made about the future. I am hopeful about solutions being found, but remain disturbed by how pervasive the desire to know about the Kardashians, Lindasy Lohan, Snookie, Brittany  Spears. I suppose I am stating the obvious, If we disregarded this information, would it cease to be reported?  It is a distortion of values. It is more important to be famous than to actually know anything. What is the truth behind the MF Global demise? How do we solve the issues facing us as a society; that the dean of St. Paul’s Cathedral resigned over the possible eviction of the Occupy London protestors.

A much healthier event taking place right now:

THE ART OF YACHTING

This is a much larger subject than the space I am giving it today. The more I think about it the more I might expand this thread. It should be no surprise to any of us that the America’s Cup is the focal point. It is specific, and has had a long history. Sculptors, painters, illustrators, photographers, film makers all have made the Cup the object of their work.

OCCUPY WALL STREET

The Occupy Wall Street movement is becoming the elephant in the room. I refer to myself as part of the woodstock generation; mostly because I was in college at the time. Most of my dorm mates burned their draft cards; an action they did not take lightly. (I am reminded that Russell Coutts refers to my generation as the Flintstone generation, how little he understands.)

I watched Kent State happen with shock. All of this led me to believe that by the time I was a fully functioning part of society, we, collectively would have found solutions for so many of society’s problems. Instead I watched as those problems grew much worse.

Had there been a draft by the time of the Iraq war, the war likely would never have happened. It became a war for the poor and misguided.

No one on Wall Street broke a law, that I am aware. But something went terribly wrong never-the-less.

If we outlawed lobbyists and limited contributions to political campaigns I believe change would occur very quickly.

People complain that the protesters have no demands; I see a system that is broken; one that needs EVERYTHING FIXED. I remain troubled that we allowed ourselves to get where we are. But I am relieved, and comforted to see the protests finally happening.

MIDDLE SEA RACE AND THE WHITBREAD RACE

Something we all tend to forget is just how well J boats rate. They also tend to sail well, but perhaps more importantly they seem to outsail their ratings. I cannot count the number of races, where we considered we had sailed well and were biting our nails about a j boat close on our heels, wondering if we would have saved time against the competition.

The Swans, a Sparkman & Stephens staple in the seventies. We have forgotten how dominate these designs were. “Noremya” a Swan 48 was the first foreign yacht to win the Bermuda Race in 1972. I sailed this boat in her next life as “Weald” and was so impressed that we could power away from “Carina” often.

Skip Novak’s remarks demonstrate how captivating the anecdotes of life can be. Todays boats are so fast, there is little time for those little stories. Sitting on the rail is now so critical to a yacht’s performance; so life on a boat is now pretty much eating, sleeping or sitting on the rail. Not much time for shenanigans.

 
Rolex Middle Sea Race 2011, currently underway, is organized by the Royal Malta Yacht Club. Approximately 30 boats are still racing and 39 boats have finished as of 18.30 CEST. 

After racing over 600 miles, the J/122 Artie crossed the finish line at 15.22 CEST, eight minutes in front of Jaru Team EC, a J/133, and, in doing so, was the first Maltese boat home. That finish also put the local entry, co-skippered by Lee Satariano and Christian Ripard, ahead of Rán (GBR) as overall handicap leader.

However, the crew of Artie will have to cool their heels on the Royal Malta Yacht Club terrace as they wait to see if any boat still racing might be able to beat them on handicap. A formal announcement of the overall winner will be made tomorrow at 1200 CEST at the Royal Malta Yacht Club.

Owner Lee Satariano was clearly relieved to beat his local rivals home and said, ‘It was very achievable because we worked very hard. The crew has been preparing the boat for the past several months, we even have a new sail wardrobe. Being the first Maltese boat gives us a big satisfaction because the local competition is very, very big.’ As for the possibility of an overall victory, he was more cautious and said, ‘The competition is growing every year. In the past we’ve had two second place finishes; we hope this third time is even better.’

Christian Ripard, co-skipper said, ‘It’s a great feeling. We ended up doing most of the race alongside or crossing tacks with Jaru; it’s nearly a rerun of last year, though this time we managed to beat them.

King’s Legend Joins Legends Fleet

VOR LegendsAlicante, Spain: King’s Legend, the boat that finished second in the Whitbread Round the World Race in 1977-78 with Skip Novak as her navigator, has become the latest entry to the Volvo Ocean Race Legends Regatta and Reunion in Alicante, Spain in November after securing sponsorship from The Jalousie Enclave, an exclusive property development in a UNESCO World Heritage site, Val des Pitons on the Caribbean island of St Lucia.

In 1977-78, owned by English gentleman Nick Ratcliff, flying the British ensign and drawing on the talent of a multinational professional crew, King’s Legend — a sloop rigged Swan 65 built by Nautor in Finland — came second behind Flyer.

“On King’s Legend we had a real boat race on our hands as the pre-race favourite, Flyer, had exactly the same handicap rating,” Novak, one of the Legends Ambassadors, recalled. “The wealthy Dutchman, Cornelius van Rietschoten beat us into Cape Town by only two hours after a hard-fought upwind battle in the South Atlantic. But the most poignant moment for me was seeing Table Mountain on the horizon from 50 miles out, having navigated there with ‘a sextant and a time piece’.

“The next crew drama was when a leak was discovered at the rudderpost, which was opening and closing in the huge waves. We made contact with the crew of Adventure, Great Britain II (both yachts will attend the reunion), and Heath’s Condor, all of whom agreed to listen out for King’s Legend via the radio every six hours.”

After two days of worry, the crew was able to bring the leak under control. However the event was a stark reminder that these are desolate oceans populated only by albatross, whales and ice, with no shipping within thousands of miles.

After a massive broach while stampeding towards Cape Horn, water from the heads found its way into the SSB radio, which immediately ceased to function. “It may seem strange today,” says Novak, “but no-one was in the least alarmed that we were completely cut off from the outside world.”

By being one degree of latitude too far south, King’s Legend lost Flyer on the scorecard forever, and trailed her across the finish line to take second overall.

ETHANOL IS BAD FOR MARINE ENGINES

TESTING CONFIRMS DANGERS OF ETHANOL IN MARINE ENGINES
On Friday (Oct. 21, 2011) the U.S. Department of Energy's Office of Energy
Efficiency & Renewable Energy released the results of two studies on the
effects of using fuel that is 15 percent ethanol in volume (E15) in marine
engines. The studies were conducted on engines provided by two marine
engine manufactures; Both are members of National Marine Manufacturers
Association (NMMA).

The long-awaited reports show significant problems with outboard, stern
drive and inboard engines. Results of the reports show severe damage to
engine components and an increase in exhaust emissions, reinforcing the
recreational boating industry's concern that E15 is not a suitable fuel for
marine engines.

Emissions and durability testing compared E15 fuel and fuel containing zero
percent ethanol (E0) and examined exhaust emissions, exhaust gas
temperature, torque, power, barometric pressure, air temperature, and fuel
flow. Specifically, the report showed degraded emissions performance
outside of engine certification limits as well as increased fuel
consumption. 

In separate testing on engine durability, each tested engine showed
deterioration, including two of the three outboard engines, with damages
severe enough to prevent them from completing the test cycle. The E0 test
engines did not exhibit any fuel related issues. -- Read on:
