Anchor .. Basics

Anchor is one of the most basic skills of a sailor must overcome of. This article covers the basics and theory, those whose experience may want to switch to other articles on the subject. Anchoring is an art, combined with a bit of science.

In simple terms, most anchor is to attach your boat to the seabed via anchor and a chain or rope. The aim is that the boat stays put and does not drift off (within the limits governed by the length of the chain or cable).

All the anchors of the type according to work the same way … they have gone down at sea on their chain, and once they are in contact with the bottom of the growing chain is paid out as the boat drifted towards the back is pushed by the wind or tide.

At a certain stage chain is no longer being paid and then made quickly. The boat is now in reverse, dragging in front of her chain and anchor at the bitter end. Because the chain is heavy, it tends to fall down vertically, then run along the seabed horizontally to the anchor.

The anchor is designed so that when it is dragged on the seabed horizontally it tries to widen like a cat. Depending on what the substance is made of her by herself digging, often until it is completely and totally buried, or the case of a rocky bottom is clinging to a rock or crevice.

At this point, the boat stops at backward, and the chain (Or a combination chain and rope) are …. sometimes tense tense bar. Once the dynamics of the boat is stopped the chain relaxes a bit and the boat will be happy to cast anchor.

In normal conditions, the weight of the chain will ensure that there is always pulling on the same horizontal anchor, so the more tension that occurs as the anchor tends to dig in.

It is part of the art of knowing exactly how Seamans chain to pay off, and this may vary depending on the depth, the nature of the seabed, and the weather, tides, sea conditions and at anchor.

The aim is to ensure that no matter what happens the anchor is always a horizontal versus vertical traction on it.

When the tide turns, or piping from the liquidation of another direction, the boat tries to drift in this way. He drags the chain in front of her, and tension on the anchor point changes direction. If it is well dug in it may well stay there, on the other hand, it can be dragged by the change of direction, and then he has to reset the same way it was first deployed in. .. but in a new direction.

Thus, whenever an anchor is under strain to come on the issue in a totally new, it is vulnerable to break seabed, and have to reset again.

This means that if you set a single anchor point, caution is recommended at the beginning of the tide or wind shift significant.

If you imagine the anchor as being the central point, and the boat swinging around her 360 ° on its chain, is the anchorage zone can travel by boat and it is called the swinging circle. The length of the chain or chain and cable paid is called the scope, and the chain (or rope / chain combination) paid is called the anchor horseback.

When it is time to lift the anchor, the string is pulled (which pulls the boat to a point somewhere above the anchor) and the anchor is "split". Anchors burst when the direction of pull is vertical, as opposed to horizontal. Chain and the anchor are back on board, and go.

This is explained in its anchorage the most basic terms, and the same thing if you anchor the boat or cruiser. A horizontal traction on the seabed in the excavations position, a vertical pull on the chain anchor dislodges. A complete change of direction in the attraction may dislodge the anchor, and normally it will reset … provide traction on it is horizontal.

The most important thing for beginners to understand is that the anchor is not the same that mooring, the boat can walk on its scope within its circle swinging. When the anchor breaks and resets itself the boat can move off station, the distance depending on how long it takes to dig the anchor again.

Therefore the choice a place to anchor, you'll be looking for a place without big waves, because in addition to making things extremely uncomfortable, they can jerk the anchor. You'll be looking for a place where the tides are not too fierce, the main flow of the tide. You will be looking one where you have room to swing. And you will be looking for a place with an appropriate background where your anchor can dig properly.

You'll probably avoid anchoring on the rock as anchor depends then hang a flush. With the start of the tide or the wind in the anchorage will find another outcrop cling. Finally, the anchor can indeed get trapped in crevices, and you will not be able to wear it.

Mud, provided it is good not too gloopy, the sand is good provided it is free of weeds (which can interfere with the anchor digging).

You pay the exact amount of scope to allow a horizontal pull on the anchor … for now, let's just say 3 5 times the depth of the water .. It is a good starting point.

You look at your anchor dig, and once it has bitten, you can use some backing to dig a little more.

Once you are safely at anchor, you must pay attention at the end of the tide or wind shift, that's when you might start to drag.

Once you've done all this your satisfaction, look and see if some idiot does not come and anchor just above you!

That's all for this primer article, seems simple, but you can spend many, many, many years of learning more and more about the subject as you go along, and other articles of this series other aspects of the art of anchoring.
