Loïck Peyron wins La Route du Rhum 2014



From MySailing

Thirty two years after the first of his seven attempts, French ocean racing star Loick Peyron won the Route du Rhum - Destination Guadeloupe this Monday morning (TU) when he crossed the finish line of the solo race from Saint-Malo France to Pointe-a-Pitre at 04:08:32 TU/05:08:32 CET/00:08:32 local.
The lone skipper of the 31.5m (103ft) Ultime trimaran Maxi Solo Banque Populaire VII completed the 3,542 miles course in 7d 15h 8m 32s.
His elapsed time is a new outright record for the course passage, which was first raced in 1982, breaking the 2006 reference time set by Lionel Lemonchois (7 days 17 hours and 9 minutes) by 2hrs 10mins 34secs.
Peyron sailed the 3,524 NMs theoretical course at an average of 19.34kts.
In reality he sailed 4,199NM at an average of 22.93kts.

Positions 5 hours after BP arrival

Skipper of the 14 man 2011-2012 Banque Populaire crew which holds the outright Jules Verne Trophy sailing non-stop around the world record, Peyron has a longstanding special affection for La Route du Rhum as it is the Transatlantic race which launched his solo ocean racing career as a 22 year old.
Until today he had finished fifth twice and was forced to abandon three times in the ORMA 60 trimarans in 1990, 1994 and 2002.

 Comparative size of the boats

At the age of 54, his Route du Rhum triumph is another new summit for the sailor from La Baule, Brittany who turns his hand with equal skill to all disciplines of sailing from foiling Moth dinghies to the giant multihulls as well as the America’s Cup.
Ironically he was only enlisted two months ago to replace skipper Armel Le Cléach’h who injured his hand.
Maxi Solo Banque Populaire VII’s win was built from the first night at sea.
After negotiating a difficult upwind section Peyron was the first to turn off Ushant, perfectly timing his key passage through the front.
He opened his lead in almost all sections of the course, except momentarily when he lead into a bubble of light winds under the Azores high-pressure system.
But his approach to Guadeloupe regained distance and when he crossed the finish line second placed Yann Guichard on the 40m Spindrift was 180 miles astern.
It is the second time in a row that the race has been won by the same trimaran, which was designed by VPLP.
In 2010 Franck Cammas won on the same boat when it was Groupama, in a time of 9 days 3 hours.

His win is all the more remarkable for the fact that Peyron stepped in for the injured Le Cléac’h only two months ago and many times pre-start in Saint-Malo he voiced his concerns about the magnitude of the physical challenge he faced, playing down any suggestions or expectations.
In fact Peyron had originally planned to sail this Rhum in a tiny 11.5m trimaran called Happy.
But his vast experience and technical skills on multihulls filled the gap, complemented by the accomplished skills of his routers ashore – who plot his course for him – Marcel van Triest and Armel Le Cléac’h.
His two ‘guardian angels’ kept his course fast, simple, smooth and safe.

First words from Loick upon arrival: “It is a very nice victory but a team victory. I was not supposed to be on this boat two months ago. I was supposed to do the Rhum race on a very small yellow trimaran, which will be the case in four years time, I will be back. But it is not a surprise because I knew that the boat was able to do it. I knew that the team was able to help me a lot.
"Armel is here but he does not want to be here on the pontoon. But he is here and in fact we spent the week together. We were talking all the time, before and during the race, and he gave me so much help.
"It was really tough, but I am really impressed by the job that Yann Guichard has done since the start. His boat is bigger, this boat is big but it is nice.
"The last day was difficult, from the early hours off the Désirade, there was a lot of maneuvering to be done. It's been seven editions for me! This is an exceptional situation, to stand in for Armel and to be able to skipper such a beautiful boat. This victory is thanks to Team Banque Populaire, as whole team we did this.
"I never imagined that I would win a Route du Rhum on a boat like this. A race like this is never simple and that is what is so exciting and incredible about it. It is also very stressful for the boat to withstand such high speeds in bad seas. I was able to sail the boat well but was scared. This is what the multihull game is all about. You have to constantly manage the boat. One night I fell asleep at the helm and nearly capsized the boat. This is a great victory; possibly one of the nicest and breaking the record is the cherry on top of the cake.”

Edges of sanity

Edges Of Sanity. from Finisterre

It’s been said
On far shores, weary mariners hear voices
Songs so beautiful they cast a spell
There is no choice but to hear.

Stunning siphonophore : marine biologists release incredible video of a borg-like sea creature

The video was captured by the Hercules diving craft, part of the Nautilus Live expedition,
which is exploring the creatures of the deep in the Gulf of Mexico and Caribbean Sea.
E/V Nautilus, the current ship of exploration of Titanic discoverer Dr. Robert Ballard,
is exploring the ocean studying biology, geology, archeology, and more. 
Watch LIVE video from the ocean floor. 


This beautiful colonial organism drifted past Hercules' cameras, and we followed it for as long as we could keep track.
They are made up of many smaller animals called zooids, and can be found floating around the pelagic zone in ocean basins around the world.
One famous siphonophore species is the deadly Portuguese Man O' War
"I can't believe that's a living thing!" declares one of the scientists watching this stunning underwater footage of a siphonophore.
The creature is not just one organism, but several that collectively serve various functions such as locomotion and even preying for food.

GPS back-up: World War Two technology employed

Many critical instruments on ships rely on GPS

From BBC by Rebecca Morelle


Technology developed during World War Two is to be used as a back-up for GPS.

The General Lighthouse Authorities (GLA) have announced that they have installed a system called eLoran in seven ports across Britain.
The GLA say many critical instruments on ships use Global Navigation Satellite Systems, and if they fail the consequences could be disastrous.
The new system, which is ground rather than satellite-based, is designed to be used in the event of a GPS failure.
"All vessels that sail today are massively dependent on GPS, " Martin Bransby, research and radio navigation manager for the General Lighthouse Authorities of the UK and Ireland, told the BBC's technology programme.
"It is their primary means of navigation - and a massive number of instruments rely on it too.

"If you don't have it, you are dead in the water."

eLoran has been tested in Harwich and Felixstowe - the UK's busiest container port

Testing for eLoran has taken place in Felixstowe, the busiest container port in the UK.
Each year, three million containers are brought in on some of the biggest ships in the world.
Safely manoeuvring these vessels in this packed waterway is vital, and currently the only way to do this is with the help of GPS.
Onboard the Galatea, a ship that is 80m (260ft) long, the GLA have been finding out what happens if the satellite system goes wrong.
Martin Bransby demonstrates a GPS failure by pulling the plug on the ship's receiver.
Within a few seconds, alarms start to sound on the bridge as one by one the instruments stop working.
"This is the gyrocompass - it steers the ship - you can see it starting to fail," says Mr Bransby.
"If we walk over here, this is the radar, and that's not working either. This is the dynamic positioning: it holds the ship's position, that's not working.
"The electronic chart display becomes unusable. Even the ship's clock stops working."
In a series of tests, the GLA have found that almost every bit of kit on the boat uses GPS - even the onboard satellite entertainment system.
Mr Bransby says: "You can imagine standing watch on this ship, it's the middle of the night, it's dark, it's foggy, you are in the English Channel, and then this happens.
"What do you do? You're in a right mess, basically."

On Galatea, a dual eLoran-GPS receiver is now in place

Losing GPS is not a just theoretical problem.
The system works using a fleet of satellites orbiting high above the Earth, but the signal they transmit is weak and can be easily interfered with.
Other sat-nav systems - such as Galileo in Europe and Glonass in Russia - have the same vulnerabilities, says Prof David Last from the Royal Institute of Navigation.
"A little bit of power from a jammer on the frequency used by GPS close to your receiver can deafen it, and it won't be able to hear the GPS signals," he says.
"For example, jamming is a real issue in Korea. There have now been three occasions when the North Koreans have transmitted high-powered jamming in South Korea."
The Sun too can knock satellite systems offline, he adds.
"It starts to transmit radio noise during solar storms, so intense that it either makes GPS positions wobble about or causes GPS to be lost across the entire sunlit side of the Earth."

Particles hurled out by the Sun can knock satellites offline

Until now, there has been no "Plan B" if GPS goes wrong, but the GLA says eLoran will be an important tool.
The technology was developed during World War Two.
The Long Range Navigation system (Loran) was the brainchild of US scientists and was used to guide US Navy warships as battles raged in the Pacific.
After the war ended, it was updated and renamed Loran-C, and adopted by mariners around the world - until GPS took over.
Now though, rebranded as eLoran, its infrastructure has been upgraded to make it more accurate and it is making a comeback.

While GPS transmitters are based in space, eLoran's are based on the ground.
Radio stations transmit long-range radio waves.
They use the same method as GPS to pinpoint position, but there are crucial differences.
Professor Last says: "The neat thing is this: the radio frequencies which eLoran transmits are completely different from those of GPS.
"The power levels, instead of being very weak, are very strong; the propagation of the radio signals is very different."
He adds: "Everything that matters is very different (from GPS) so there is no common mode of failure. The result you get is a plug-and-play replacement for GPS."

The General Lighthouse Authorities have finished installing eLoran in seven ports along the east coast of Britain, completing the first phase of their roll out. It is now in place in Dover, Sheerness, Harwich and Felixstowe, Middleborough, Leith, Humber and Aberdeen.
Onboard the Galatea, Martin Bransby demonstrates how a dual e-Loran and GPS receiver works.
He says: "What happens inside this box is when we see some interference or jamming or a satellite failure, there is an algorithm that decides to swap over to eLoran. And it does that seamlessly."

For now, eLoran is being tested for shipping, but it could also play a role on land for the vast array of systems that use GPS.
Prof Last says a back-up is long overdue.
"Most people think of GPS as the system that runs their car sat-nav and tells their smartphone where it is," he tells the BBC's Click.
"But there is probably no area of industry, of commerce, or telecoms, that isn't now dependent on GPS. And if we lose GPS we lose them all."

This is a shortened version of the 1947 "LORAN for Ocean Navigation"
filmstrip produced by the Coast Guard as a sales pitch to commercial shipping lines to adopt LORAN (as a both a navigational aid and to assist in distress situations).
Updated with a new narration track in place of the distorted period track, the film provides a brief overview of the operational theory behind LORAN.

But the system may never go global.
The US Coast Guard is busy decommissioning the existing eLoran infrastructure.
And in Europe, the governments of Norway and France have said they will cease operations next year.
Commercial companies may take up the reins, but without support from some of the biggest shipping nations, the eLoran safety net may not be around to rescue everyone.
