The earliest Danish coins depict ships, both trade- and warships, while most contemporary literature count the ships as a matter of course. There are rarely details about sea voyages or information about the ships. When the travels are described it is only said that missionaries, tradesmen and others went from Dorestad to Denmark or from Hedeby to Birka - no mention of the ship at all. One exception is Ansgar's first voyage to Denmark where he and his companion got a ship from the archbishop of Cologne and discovered they had to share rooms with the Danish king.
The contemporary texts give barely information about the size of the vessels, the names of the ship types are known to us from poetry and a few runic inscriptions, but it is almost impossible to decide the difference between a skeith, a snekkja and a knarr. The scalds might have used these words randomly. From the 1000s a seagoing tradeship is called a knarr, but since this word in the early poetry was used for a warship, a knarr was possibly just a seagoing ship, whatever it was used for trade or war.

By help of dendrochronology and other scientific dating methods the archaeologists have established a pattern of development for the Scandinavian ships. Even lesser ship-parts can be dated. The finds are so numerous and so clear that there is now a safe and precise knowledge about the development of the art of ship-building. The recovery of these ships has given a more versatile image of the shipping of the Vikings.
There were various boats for various purposes, the simplest was the oak, a canoe hollowed from a log. This type of boat was created long before our time and was still used in Danish lakes and rivers only a hundred years ago. The Vikings built also small barges, one was found at Egernsund in Flensborg fjord, it was 7 m long and 1,9 m broad and is dated to the end of the 1000s. But their larger vessels, both trade- and warships, are more wellknown. Small freightships, less than 20 m long, were found near Larvik in Norway, in the Gøtaelv (river) in Sweden and at Skuldelev, and at the same place were found two warships. The rest of a warship was found in a pretty gravehill at the shore of Kerteminde fjord (the Ladby ship ). The wood in the Ladbygrave had rottened, but the shape of the ship was clearly drawn in a pattern formed by the iron-nails, which kept the ship planks together. In the sea were important finds of individual ship-parts, like a 2,8 m long side-roar, which was fished up from Kattegat and a 3,8 m long mast-part in Mariager fjord . Many ship parts, both used and new, were found at the island Falster in a shipyard from the 1000s, where the old ships apparently were repaired.
The times were harsh and violent in the late 1000s, and the Vikings built a system of blockage in Roskilde fjord as a protection against hostile navy attacks on the town Roskilde, which then was the capital of Denmark. The five ships in the hall of the Vikingship Museum origin from a blockage of Peberrenden at Skuldelev ab. 20 km north of Roskilde. The ships were excavated in 1962. An iron pile wall was framed down around the blockage in order to drain it. In less than four months the ships were dug out and brought up in thousands of pieces. After this came a huge work of preservation and collecting the pieces into the five puzzles, which represent the Viking ships. The finding includes five different ship types, which collectively give a unique impression of the shipbuilding and craftmanship of the Viking Age.
Skuldelev 1 (Havskibet)
|Skuldelev 1, wikipedia|
The ship and cargo might have been owned by a magnate/chieftain, who went on trade with his entourage or owned by merchants, who in commmunity were sailing the ship and do some trading in the marketplaces. The crew was 6-8 men. Havskibet could sail overall in the North Sea and the Baltic and on the North Atlantic. In favorable wind it was able to keep an average speed of ab. 5-7 knob. The Vikingship Museum's reconstruction of Skuldelev 1 is in the Museum harbour.
Skuldelev 2, (the big longship)
|Skuldelev 2, wikipedia|
The ship is built in oak, the analyze of the timber has shown that the ship was built in the Dublin-area ab. year 1042. The Vikings came to Ireland in the 800s, and they established several fortified bases along the Irish coast. The bases later developed into cities with Dublin being the most important. The Vikings lived here as merchants, mercenaries and shipbuilders.
The long narrow shape of this ship gave it a good speed potential. 60 oars secured the progress of the ship even without wind. Havhingsten fra Glendalough, the Vikingship Museum's reconstruction of Skuldelev 2, has reached an average speed of 2,5 knob with every second oar staffed. Under sails the Havhingsten has reached a top speed of 12 knob. Havhingsten fra Glendalough ( The Sea Stallion of Glendalough) is in the Museum harbour.
Skuldelev 3 (Kystfareren / The Coastal Trader)
|Skuldelev 3, wikipedia|
The ship was useful when the farmer and his entourage had to go to markets or meet at The Thing. It was well suited for sailing in the Danish waters and in the Baltics. The wind was its most inmportant driving force, but during maneuvres and in short distances in no wind the oars could be used. In favorable wind the ship could keep an average speed of 4-5 knob. Roar Ege, the Vikingship Museum's reconstruction of Skuldelev 3 has been sailing with a top speed of 8,5 knob. Roar Ege in the Museum harbour,

The Skuldelev ships were products of a long boatbuilding tradition in Scandinavia and the Baltics. There is only a little difference between the Danish ships and the ships from the Slavic areas. The basic construction consisted of keel and bow. When a ship-timber had made these, the shape of the vessel was largely determined. A ship could usually not be longer than the straight trunk of an oak.
Both the sailing and the landing wore out the slender ships. The small warship from Skuldelev had been repaired with planks from another ship. Finds from the ship yard at the island Falster illustrated, how the old ships were broken up in order to re-use well-kept timber. But the keels were not suitable for re-use, since they had been worn out from the eternal pulling on land. The effort the Vikings did to re-use ship-parts and to repair the ships show how valuable the ships were. They represented a big investment. A reconstruction of the trade ship Skuldelev 3, which was built with the use of the tool-types and methods from the Viking period, took 15.000 working hours. Skilled workers were probably able to do it in the half time or at least lesser time, but even this was a big effort.
A well-functioning seagoing vessel from the Viking Age could handle very rough weather conditions. This was demonstrated dramatically when a reconstruction of the big trade ship from Skuldelev came safe through wind gusts of 35 m/sec at the coast of Greenland. Lesser sea seaworthy ships would have been shipwrecked - and many Viking ships probably did.
