All Viking ships are clinker built; the planks were overlapped at one edge and riveted together. In clinker shipbuilding you start build the outside first, and then put a frame inside it. The other style Viking Yacht Builders Korea of wooden shipbuilding, used by the Mary Rose and the Victory, is called carvel. In this style, the frame of the ship is made first, and planks are attached to it. At the end of the middle ages, Carvel had overtaken clinker as the method of choice Viking Yacht Builders Korea Viking Yacht Builders Korea for making larger boats.

Does this mean that clinker was a poorer method of making boats? Not exactly�. The advantage that carvel has Viking Yacht Builders Korea over clinker is that it can be made using any quality of wood, whereas to make a Clinker boat, only the best wood can be used.

Because the planks on a clinker-built boat overlap, they add strength to the boat, so the frame can be lighter. The Vikings built their boats using simple tools � it has been said that you can make a Viking boat with nothing but an axe Viking Yacht Builders Korea � but they used them in sophisticated ways. They followed the grain of the wood, to get the most strength and flexibility for Viking Yacht Builders Korea the lowest weight. Carvel boats tended to be made with sawn timber.

Saws are harder to make than axes, and they tend to cut across the grain. This means that they can cut any timber any way you like, but the result will be weaker and less flexible than an axe-cut timber. A heavier carvel boat will tend to fall into them, giving a rougher and slower ride.

And the Viking Yacht Builders Korea Viking Yacht Builders Korea reasons that the clinker tradition stopped being used for larger vessels? Well, no-one is quite sure. Ships were being built with multiple decks, which Viking Yacht Builders Korea Viking Yacht Builders Korea needed a heavy frame anyway to carry the cargo � or the new-fangled cannon that warships were starting to mount. The world was Viking Yacht Builders Korea changing, and the heavy framed carvel boat was the one that survived that change.

A master ship-builder would set the design for the Viking Viking Yacht Builders Korea Viking Yacht Builders Korea ship, and he started with the keel. However, it was the two curving posts at the front and the back of the ship Viking Yacht Builders Korea � the stem and the stern � which would determine what sort of shape the finished vessel would be. It is from this vital Viking Yacht Builders Korea first stage that he got his name � the Stem-smith.

The Stem-smith was probably responsible for making sure that the hull was the correct shape. This would involve cutting planks in ways that seem counter-intuitive to us; seeing the planks out flat can lead you to wonder how they ever could fit together. However, the stem-smith appears to have been an expert in taking a two-dimensional plank and turning it Viking Yacht Builders Korea into a three-dimensional ship.

It is only with modern computer modelling and an understanding of how boats move through the water that we are Viking Yacht Builders Korea starting to see how sophisticated these Russian Yacht Builders Zoom shapes could be. For instance, Viking ships did not have deep keels, because there were few if Viking Yacht Builders Korea any harbours that could take them. This meant that, when sailing with the wind anywhere other than right behind them, there was a tendency to be blown off course mariners call this leeway.

I am not, of course, claiming that Viking boat builders were imbued with supernatural Korea Builders Viking Yacht powers, or knew modern hydrodynamic theory.

It was simply the culmination of centuries of experimental boatbuilding, with the boats and possibly boat builders that Viking Yacht Builders Korea survived being copied by the next generation.

On one of the vessels found being used to block a channel at Skuldelev, in Denmark, it was found that there was a relationship between the length of the keel, the size of the stem post, the number of planks, and the radius of curvature of the plank lines at the stem.

Probably many boats, if not most, were built with a set Viking Yacht Builders Korea of ideal proportions in the mind of the boat builder. Timber was used green � in other words, shortly after felling. This is different to more modern practice, where the timber is "seasoned" � left to dry for several years. Green wood is easier to work, and more flexible, which can help with some of the more complex shapes found in Viking boats.

Wood can be kept "green" for several years by keeping it immersed in water � a stem or stern of a Viking style boat was found on the island of Eig in what, a thousand years ago, had been a lake.

As it had never been used � there were no indications of rivet Viking Yacht Builders Korea holes � it was probably made up when the boat-builder had got a spare piece of suitable timber, and he was waiting for a similar bit for the stern or stem which never arrived. It is also possible to steam green wood without complex equipment like the Viking Yacht Builders Korea steam boxes used today.

Simply by heating a plank over a fire, the moisture inside the wood heats up and causes the fibres to loosen. This means that � for a few minutes � it can be twisted into shape with less danger of it splitting and breaking.

It is highly likely that this was done during Viking times � we know the technique was used to make "expanded" log boats, for example. Oak or pine were the preferred woods to construct boats from.

The only reason for using one over the other appears Viking Yacht Builders Korea to be what was growing locally. Even in the "pine building" regions mostly Northern Norway Oak was still the wood of choice for the Viking Yacht Builders Korea keel, so it must have been imported from the South.

It's likely that masts and yards were made out of pine, so Viking Yacht Builders Korea it may have been a two-way trade. The big difference between oak and pine is how planks are made from them. For oak, large Dutch Yacht Builders Enkhuizen Ko straight trees of around two centuries old are cut, and then using wedges split multiple times like slices of a pie � it Viking Yacht Builders Korea Viking Yacht Builders Korea might be possible to get upwards of 60 planks from one tree. A pine tree will yield only two. One advantage of pine over oak is that, as they age, pine planks will bend depending on whether the bark side of the plank faces the water or Viking Yacht Builders Korea Viking Yacht Builders Korea the inside of the boat, so they can be used to enhance the curve of the vessel over time.

Most of the British Viking Yacht Builders Korea Isles was probably an oak building area, although boat builders probably used the nearest timber to hand.

Certainly some boats appear to have been Builders Korea Viking Yacht repaired with anything, including bits of other boats! It is, however, the strongest way that you can process wood, because it works with Viking Yacht Builders Korea the grain of the wood � it gains strength by following the way that the tree grows.

The log is split using an axe Viking Yacht Builders Korea to make a cut, running up and down the trunk. The split is widened and extended by driving wedges into it, until eventually Viking Yacht Builders Korea the whole trunk splits in half.

At this point, for a pine tree, the splitting stops. Younger pine trees are used, which are only Viking Yacht Builders Korea about half the diameter of the an oak. Oak trees can be split further; each half is split into quarters, each quarter split into eighths, and so on. In fact, from a year-old tree, with skill, about 64 planks can be obtained.

They are all slightly triangular, Viking Yacht Builders Korea Viking Yacht Builders Korea and quite rough, so they are smoothed down a little, like the pine planks. For the frames inside the ships, the Viking shipwrights used another type of timber that is rarely seen today � the grown timber.

A grown timber is simply one that has grown to the right shape. The grain runs in the direction that was needed, making the timber incredibly strong. Viking ship frames are like display Yacht Korea Builders Viking cases of grown timbers. For instance, the stem and stern posts would be taken from large, curved branches.

Where two parts of the frame are to meet usually a weak spot that needs re-enforcement the Vikings used a single timber, cut from a branching element of a Viking Yacht Builders Korea tree. The tools used for this smoothing would appear to us at first glance quite simple. An axe with a long blade could be Viking Yacht Builders Korea used to smooth, as could an adze and a draw knife. Planes were known, and are shown being used for boat building on the Bayeux tapestry.

Later on in the process, augers would start holes for rivets and trenails. Profiled irons would make decorative marks in Viking Yacht Builders Korea the planks, or carve channels for caulking. These apparently simple tools were so good that they remained unchanged for centuries � in fact, until Viking Yacht Builders Korea Viking Yacht Builders Korea Viking Yacht Builders Korea the introduction of modern power tools! To make a Viking ship, you lay down a keel first. The keel is made of Oak, Viking Yacht Builders Korea as long and as straight as you can get. Often this shape will change along the length of the keel, changing from a V section at the stem and stern front and back to a U section in the middle.

This is to help shape the final Viking Yacht Builders Korea lines of the hull. Two pieces of curved wood are attached at the front and back of the keel, the Stem and Stern pieces.Viking Yacht Builders Korea

There is some evidence to show that there was a relationship between the length of keel and the diameter of curve in the stem and stern pieces. Viking ships are pretty much symmetrical both fore and aft front and back and port and starboard left and right , Yacht Builders Viking Korea so the curve in these pieces will be the same. Two types of stem and stern piece construction have been found.

In one, Viking Yacht Builders Korea Viking Yacht Builders Korea the stems are simple curves. In the other, they are carved and notched with steps, forming the beginnings of the planks that they will Korea Builders Viking Yacht eventually hold. Although this is a lot of work to do, it can save time Hong Kong Yacht Builders Technology in the long run. It was important for Viking Yacht Builders Korea Viking ships to have the planks sweeping up and running together along the stems. It is then ready to have the planks or strakes Viking Builders Korea Yacht put on it.

The first strake to go on is called the Garboard strake dunno why, it just is and it is riveted and nailed on to the keel. Iron rivets are the most common Viking method of joining planks together modern clinker boats use copper.

Nails are used where the end Steel Expedition Yacht Builders Solution of the rivet cannot be reached � usually at the stem and stern, where space is tight. The Yacht Builders Korea Viking heads of the rivets are bent over rectangular ish washers, which are called roves. The next plank is riveted on to the garboard strake, Viking Yacht Builders Korea Viking Yacht Builders Korea Viking Yacht Builders Korea Viking Yacht Builders Korea so that it overlaps it when seen from outside.

The rivet passes through the outside of the plank near its bottom edge, through Viking Yacht Builders Korea Viking Yacht Builders Korea Viking Yacht Builders Korea the garboard strake near its top edge, and it is bent over a washer inside the boat. Caulking or luting is used to Viking Yacht Builders Korea stop water from getting into the boats. No wooden boat can claim to be entirely watertight, but the Vikings did their best. It was Viking Yacht Builders Korea laid in the groove on the plank and, when the plank was riveted to the rest of the boat, created an almost watertight Viking Yacht Builders Korea seal, whilst still having the flexibility to move with the boat.

As each plank is riveted to the next, the boat would begin to Viking Yacht Builders Korea Viking Yacht Builders Korea take shape. To get the boat to the correct profile involves cutting the planks into some fairly strange shapes. The way that the ends of the planks join onto the stem and stern helps determine the profile of the boat � whether it will be a beamy cargo ship or a knife-thin warship.

The larger the ship, the more planks will be required. Long ships would require that several shorter planks be joined together by scarf joints � some of which could be quite elaborate. As the planks are added one above the other, Viking Yacht Builders Korea clamps were used to hold them in place and the frame inside could be added.
