This excerpt from a story today! I am sure everyone here will be clamouring to buy one of these little fellas to keep by the helm.....................................

'The Cutting Edge

Valencia Sailing spoke with Phil Rogers, CEO and President Catch the Wind, a company that's providing BMW Oracle with a laser sensor that could measure the wind up to 1,000 meters ahead
Valencia Sailing: What does the Racer's Edge exactly do? Phil Rogers: It's a laser device, about the size of a large pair of binoculars, that can measure the wind up to a distance of 1,000 meters in multiple ranges, enabling to you to get a map of the wind up to 1,000 meters, at multiple ranges. So, a sailing team has a tactical advantage because they can see where the best wind is, one kilometer ahead of them.
Racer's Edge measures wind speed and direction at 400m, 700m and 1,000m ahead. As a result, you just point the device where you want to and you'll get wind speed and direction along that line of sight in those three different distances. You just push the fire button and you instantaneously know that data at those three different distances. The intervals (400m, 700m and 1,000m) of this particular device BMW Oracle are using have been preset at the factory but it's something that can be adjusted.
The device has Bluetooth wireless capability, so it can be connected to an onboard computer....
It also has a wing-profiling mode, depending on how far up you point it. If you point at different angles up from the horizon it will also provide a vertical profile of the wind. So, depending on where you point it, you'll get a horizontal and a vertical profile of the wind. There's two modes of operation.
Valencia Sailing: Is this device custom-made for BMW Oracle or is the first piece of a commercial product?
Phil Rogers: It's a combination. It has some features that we worked with BMW Oracle, that we were specifically asked to incorporate, especially in the software side, but it was basically something that we built to our own specifications as a general device for yacht racing.
Valencia Sailing: How much does it cost?
Phil Rogers: The model BMW Oracle is currently using is called the Racer's Edge Professional Model. It is the very top of the line, high end version of the device with cutting-edge technology, a lot of built-in features specifically for the very high-end professional sailors and is offered for sale at US$ 149,500. It's not only aimed at yacht racing but some of the top cruising yachts could certainly benefit from this technology. We will have in the very near future, other models of this device, including one much more geared towards the general sailor'

Any takers?
 
If I was seriously into racing big boats then yes ...
It'd be nice if it could show shifts as well ... :)

Otherwise - for the cruiser ... no ...
 
WTF? :confused:

Why would I care? Timing the trip to take advantage of tides will save me an hour or two and costs nowt. That might save a few seconds or minutes and will cost a grand or so. Get real guys. A better sail would be cheaper & more effective for most sailors. Most cruisers don't even have tell-tales FFS!
 
This sounds like a silly load of nonsense to me that is hardly like to replace the strips of old shirt I have got tied to the stays.
If "general sailors" are into that sort of stuff they need to get a life or at least avoid me:)
 
$150,000 could buy a faster boat.

Unless the boat you're already on is BMW Oracle....

Obviously the "top cruising yachts" he's talking about weren't made by Bavaria, Halberg Rassey, Oyster or even Swan....

But then, isn't this how all technology starts? I'll bet the first ever wind instrument was insanely expensive, and greeted with "why would we need that?" from the sailors of the day.

Though I'm not sure if I would welcome this device on the race course. Reading the conditions ahead is a skill that separates the best tactitians from the rest.
 
Seems an awful lot of money for what for most people would be a toy? I can think of a lot of things I could spend $150,000 on for my boat, but this is not one of them.

Quite. It makes sense for Larry and Ernesto to buy something like this, even at this price, but I struggle to see how it will help the "general sailor" - even "top cruisers". My comment that $150,000 would buy a faster boat was aimed at the comment at the end, that it could be useful for "general sailors".

At 1% of the current price it would still be a very expensive toy, with limited use except on the race course. And I agree with you that I wouldn't necessarily like to see it allowed in general racing. Maybe AC, but not otherwise.
 
How does it work? I looked at their web site and can't find any clues, and I can't think of any way it could work.

By measuring the Doppler shift of the reflected signal at specific times? That would be why you have to use a laser, and a fairly special receiver that accounts fopr the price tag, I would think. That's the method used to measure currents in the sea, acoustically (look up ADCP or ACCP if you want to know about that). Basically, the faster it goes the bigger the Doppler shift. Perfectly possible to get direction as well, but probably at several times the cost.
 
sounds as if it could also be more beneficially used looking for wind shear at airports.

Maybe NimbusGB could mount on in the nose of his glider to look for lifts ?

I would guess that's how the manufacturers would explain it, but the reflected light from clear air must surely be so feeble as to be undetectable, particulary against the overwhelming "background" light at all frequencies of the visible and invisible spectrum.

I would expect such a device would be based upon a published, peer reviewed research paper, but I can't find any references on the manufacturers web site, let alone any plain English explanation as to how it works.

I saw a program on TV a few months ago about something exactly like this; they were measuring tiny dust particles in the air to measure wind shear at airports to give advanced warning of dangerous air shifts to pilots on approach to the runway.
