Many people on their first day of a course on maritime navigation ask many things about the parts of a sailboat or the most common accidents when they go out to sea. But do not get to wonder why a basic and elementary such as this: Why sail a sailboat?

When a coach or monitor asks them this question, everyone makes a poker face, half amazed. And I think it’s very interesting to start here, for something basic that you have to assimilate naturally, because in reality, we all know the answer, but we can not easily define it. So let’s go to it. To learn why a sailboat sails when it is at sea and if we do not know because nothing happens.

What is a sailboat?

If you do not know anything about sailboats, it’s best to take it easy. And little by little and with time you will assimilate everything and you will end up learning to navigate by reading so much. Or that is our objective.

A sailboat is a boat that has a peculiar type of propulsion. That is, to move or move from one place to another will need something essential. In this case, the particular thing you need is the wind. And what you will use to catch the energy of the wind and use it at your whim will be the candles. That’s why there are so many candles on a sailboat and they are so big. Because the intention of the sailboats is to take as much wind as possible to retain it or use it to its advantage as long as possible. And they will not do it randomly if not extremely measured and scientific. And is that sailboats in general and candles in particular have a lot of mathematics.

What is a sailboat for?

A sailing boat is used to train, compete and entertain.

Learn to sail

To train because it is a sport with which we will learn to socialize. The environment in which it develops is a club that will be surrounded by thousands of equal boats and it will be inevitable to get confidence with the neighbor who will come to know us and to watch our boat when we are not. And vice versa since we will watch his when he is absent and make such bad weather that everyone will hit each other.

Have fun sailing

The best way to learn to sail is to have fun.
Many of the children’s courses start with water games inside the clubs’ facilities. Even inside a pool uploaded to a single Optimist. Also inside the mouth of a port. In a corner, yes. Or in the middle of summer in days without wind, but with a big and real boat. What they use to dump or pull on it.

These learning methodologies are also based on the positive reinforcement that is dedicated to praising how well they do something and the possibility of improving it when they do something badly done, what it does is to incorporate maritime theoretical concepts in a subtle way in each child.
For example, we can tell the children to jump forward, take the sheet and carry it aft. Let’s see who wins. What will happen is that they will play while they learn new names without trying.

For the elderly we can do something more or less the same. While we spent a whole day in a cove eating desserts we learned to untie, go out, fly and return. For a whole day it will be impossible not to have stayed with a name related to the maritime experience.

Compete in sailing regattas

To compete because the next level to the use of a sailboat with ludic objectives is competition.
If as time goes by you notice how the bug itches you, it will be inevitable that you begin to ask questions. And start asking nautical terms to those around you. Over time you may be encouraged to go to see a regatta on the committee, a beacon or another boat and so, looking, you say to yourselves: I’m going to try.

This day will only be a matter of registering and participating. If you do not have things clear you can stay a little away from others and you can even choose to go in the second row when they give the exit beep.

Sailing for entertainment

Sailboats have a lot of magic because with them you can go where no one can go. Without a sailboat it is impossible for us to move by the sea and lead a normal life on and inside the boat. Everything that happens inside we can turn it into fun because they are designed to imitate houses. And so, be able to eat, sleep, sit or clean up, being able to bring any luxury or entertainment from home to use it quietly. Meanwhile not a billiards all game will go well.

On the cover; which is the external part of the ship where we tread; We can make games with other people, although we will be limited by the shape of the cover. And what we can do is use the pole placed ninety degrees (90 degrees) to jump into the sea with a rope as if it were a zip line.

You can learn a lot without going to class because we can use a sailboat that we have available from a contact, to go on gastronomic outings near where we have moored the sailboat just to have a good time. And without wanting to, we’re going to have to repeat all the maneuvers again and again.

How does a sailboat work?

The upper part of the sailboats imitates the birds. That’s why humans have managed to fly. And the bottom part of the sailboats imitates the fish. That’s why we’ve managed to get from one place to another with submarines.

What happens with sailboats is that they use the natural dynamics of two animals at the same time.

To understand how sails work on a sailboat you have to understand why airplanes fly. And for this you have to know why birds fly.

Birds have wings that beat and allow them to go forward. Once they achieve speed that produces an air that will move their feathers. That air is called apparent wind and we will see it little by little on this website, since someday we will need it to see how some sail boats sail like the Windsurfs. That they are quite special.

Once a bird has this little wind, the wings create by themselves a depression or low atmospheric pressure on their wings. Exactly in its convex part. In this case it is your top part. And they do it because the wind has to travel more surface to reach the end of the wings. That is, if two particles enter the wing at the same time and leave at the same time, some will have to go faster to avoid being late. In this case it will be the one that has to travel the most road. If we are two friends and one has to get home by bike and another on a motorbike, the one on the bike should go very fast to arrive just like the colleague. The same thing happens with the air and the sea.

Ok, so far we know that there are particles of air and sea that come out and arrive the same. But what happens in the middle is what makes sailboats sailboats and can go from one place to another by the sea. And eye, because the planes too.

At the moment when the wind from the top of a bird’s wing or an airplane goes faster than the one below, that will create a low pressure; or a very large suction; upwards from the wing of the plane, the bird and the sailboat. But … now that we begin to understand it, we can have the first doubt. If this pulls up a bird, I understand that it flies. If that stretches up the wing of an airplane, I understand that it takes off. But if it happens behind the sail of a sailboat … Why is it not going sideways? Because there is something that prevents it. And that’s the centerpiece or the keel. These appendages that are under the sailboats, and that are not seen, prevent the sailboats from going sideways and, little by little, they will move them forward.

What is the keel of a sailboat for?

The keels and the orzas of the boats to candle prevent that the sailboat moves of side and it restrains so that it goes forward.

What is the rudder of a sailboat for?

The rudder of a sailboat serves to maneuver. Direct the ship to where we want. And according to what we have just read, the part of ltimón that is submerged in the water; what is the shovel; it will help the keel or keel so that the whole boat does not go sideways.

What is the difference between a keel and an orza?

The centerboard is large, deep and is in the middle of the boat. While the keel is shorter and runs the sailboat bow (front) aft (behind). The keels we will see many in the boats that are stranded (above the beach, for example). We can see them because they can be made of wood and about 40 centimeters deep.
The clubs can be seen from afar in the dry docks (place to ship marine vessels) at the moment when a sailboat is resting on a large metal structure called a bed or bunk.

How does a sailboat’s centerpiece work?

We will see it in depth on another page, but this way, in general and as a preview, the keel of the boats or the orzas imitate the fins of the fish. And what you do is separate the water to throw it back with force. Thus creating an impulse backwards of the sailboats so that these sail forward.
It is a rear propulsion that provides a front reaction in acceleration mode.

How is it that you can go anywhere sailing?

By way of conclusion: You can go anywhere by sailing because the patterns of the sailboats change the position sails, to modify the suction created by the sails on the back. Like the jet of a jet ski, if we change the jet side we will change course. The same goes for candles. If we change them, or trimming, the suction or low pressure that we have behind the sails will change position. This will make us change course.

Why does a ship sail?

In summary: As we have seen, a sailboat sails because the sails create behind them a suction that drags it on its side. The orza prevents it from going sideways and throws it forward. The rudder blade forces him to change course and we trim the sails to adjust the bearings to the millimeter and increase the speed.
