[MUSIC] So let's talk about Polar Diagrams. Polar Diagrams as we discussed are an essential thing to actually make a weather routing. It is the potential performance the boat can do, or yacht can do. Right? Here's a full set, covering the whole range from four knots down gale force winds. If I take out one. Let's take out this one for 16 knots, for instance. And I see a breeze day in Palma de Mallorca. But they have to mention, what does this mean first of all? Because this covers, right, I'll take this down here. It covers the whole range from zero, through 90, through 180 and then again, 360 degrees. Because with a boat you can point in any given direction. However, if the wind is coming from here and the wind is coming from here. It is extremely slow, or even impossible to go straight into the wind. The sails will be flapping. So you can only go either on port with the wind coming from here, or in starbord with the wind coming from here. The better the belt is, the closer it can go to the wind. Modern yachts can go quite close to the wind. Pinta from Mr. Columbus would go like this, and this is where a modern yacht will sail. And you can see straight away here that for instance at 48 degrees from the wind, this yacht can do 11.3 knotts. However, if I sail further away from the wind, which I will now do, you can see that at, for instance, 112 degrees to the wind, between my arm and the blue line, that will do 17.3 notes. Six notes quicker. One note is 1852 meters, That's about 11 kilometers every hour, 24 hours a day. That's a lot of kilometers, right? So the weather routing program will help us to decide if we want to go here for instance, if we're going to go like this, or if we go like this a lot faster with a longer route. But maybe there's something in our future that will allow us to come back on a quick angle again.
