Strategies for winning. Meteorology in a round the world regatta

39 個評分

In this course you can learn about the mechanics of global weather, the foundations of ocean meteorology, predictive modeling and how sailors receive data via satellite and use high-performance navigation software. This course looks at oceanic meteorology and climatology through the lens of the sport of sailing. You will gain a basic knowledge of meteorology needed by sailors to take part in a regatta such as the Barcelona World Race, the only double-handed, round the world regatta with no stops. You will learn about the strategies employed during a round the world regatta and how these are put to use on board the latest ocean racing yachts.

The sailor as meteorologist

In this module you will learn how sailors use meteorology to sail around the world and to win round the world regattas. All of their interest is focussed on the wind and they need theoretical, but above all practical, knowledge to help them to take the correct decisions at sea. Remember you can access to the help forum. If you are experiencing difficulty learning or accessing course content, or if you simply want more information.

I'm sitting where the skipper is going to spend a few days

controlling everything that is happening on the boat.

This is the central area of all electronics systems,

communications, computers, etc.

You can see this screen here, is the one

where skipper can control all autopilot.

This red button tells you whether you have it ON or OFF,

and from here he will be able to select what

navigation modes wants to use for the autopilot.

Then we have this phone,

this and this one, that make up the satellite communication that the boat carries.

This is the Fleet system that communicates through the satellite dish.

This is a security system in case the two fail

to be able to maintain communication and to be able to download some data,

and this is the Iridium system, which is what will allow you

to work also with the satellite to download the reports, forecasts, etc.

As you can see, here we have another series of screens, a very important subject,

I forgot, is the barograph.

Of course, as I said before, meteorology is a very

important in navigation, and what I said to you that from

a meteorological report we have to know the current situation.

Through this barograph we can know what atmospheric pressure we have,

as well as the trend that it followed in the last hours.

And here we have the computer screen with its keyboard.

As you can see is a fully waterproof keyboard so no

water can damage it.

And the mouse is not fully waterproof but there are several spares,

And here is the computer screen, the computer itself

is here inside, with its emergency backup

tucked inside an insulated box, to protect it from the blows,

and from water, etc., etc.

Obviously, this whole panel full of screens

of all kinds is the nerve center of all

the vessel in terms of electronics and electricity,

you also have sensors that indicate keel movements, etc., etc.

This is the most sensitive point of the boat.

From here you have control of everything, if here things start to fail,

things get complicated.

Therefore the skippers know very well that it is a Sancta Sanctorum of the

boat that is, so to speak, the brain of this ship that

is always with us and that has to carry us to good port.
