 The Viking era lasted from the
first half of the eighth century and the following three hundred
years. The Vikings went north to Greenland, south to Baghdad, east to
The Black Sea, and West to North America. They raided Paris and
controlled the British Islands. In the booklet one of the most
recognized experts on the Viking Era, the Director of the Viking Ship Hall
Museum in the old Viking Capital Roskilde, Mr. Jan Skamby Madsen, in a brochure is
telling as much as possible in so few pages about the three centuries
of the Viking Era. Three Centuries that changed Denmark from being an
almost unknown heathen area into a well-defined kingdom belonging to
the European Christian Societies.
The Viking ship
For good reason the ship has become a symbol of the Viking era.
Seaworthiness and competent seamanship were the basis of the
unification of the island realm of Denmark and a prerequisite of
the numerous Viking cruises into other parts of the world.
Contemporary west European sources provide scant information about
ships and navigation but in the poetry of the later sagas the
importance of the ship in daily life is treated more realistically.
However, the allimportant clue to the shipbuilding of the time
originates in archaeological finds.
In Viking ship research the classics are the two Norwegian
burial ships known as the Oseberg and the Gokstad which were unearthed in 1904 and 1880 on the west bank of the Oslo Fjord. They
are magnificent royal ships, dating to the years 800 and 900,
respectively. Burial by ship is known also in Denmark, at Ladby on
the island of Funen.
The Nordic shipbuilders went for lightness, strength and
resilience in their vessels. The typical feature of the Viking ship
is that it tapers at both ends with a smoothly curved transition
between keel and stern. Ribs and planks ensuring the interior
shoring are placed symmetrically abeam and regularly distributed
lengthwise in the boat, while the exterior shell has clinkered
planks overlapping each other along the edges. The ship was steered
by a lateral rudder placed at the stern end in the right side of
the navigation direction. The propelling force was sail and oars.
The ship had one mast and one rectangular sail: a square sail.
Speaking somewhat simply, the Viking ships can be divided into two categories: merchantmen and warships.
 The Viking Ship Museum at Roskilde Fjord.
The span of the Viking ship construction was well demonstrated
in the five Viking ships found at Skuldelev in Roskilde Fjord. The
ships, which were no longer in service, had been filled with stones
and scuttled by the mid1000s in order to close one of the lanes
leading into the important commercial town of Roskilde. In 1962 a
sheet piling was rammed down around the closure, the water was
pumped out and the ships excavated. The five Skuldelev ships
represent five different kinds of ship, two merchantmen, two
warships and one ferry or fishing boat. The larger of the
merchantmen was a hefty cargo vessel, 16.6 m long and 4.5 m abeam.
It is probably the knarr type, an oceangoing freighter whose range
included the North Atlantic to Iceland, Greenland and North
America. The ship was built of fir, oak and lime. The building
place may have been Norway as there was very little fir in Denmark
during the Viking era. Its capacity was a cargo of 2025 tonnes and
it was propelled by a rectangular sail of approx. 86 square metres.
The smaller merchantman is an elegantly shaped oak vessel, l4
m long and 3.4 m abeam. The ship was wellsuited for navigation in
the Danish waters and the Baltic Sea and its crew comprised four or
five people. The sail must have measured 45 square metres, and the
capacity was about five tonnes of goods.
The smaller of the Skuldelev warships is built of oak, ash and
fir. Its length is 17.5 metres and beam 2.5 metres, accommodating
13 pairs of oars and a crew of about 30 warriors. Along the gunwale
a shield strap held the shields of the crew in place.
The other warship found at Skuldelev is a long ship, approx.
30 metres in length and with a beam of 4.5 metres, with room for 30
pairs of oars and a crew of 60100 men. The ship is built of oak,
and analyses of the wood have disclosed that it was probably built
near Dublin in Ireland towards the end of the Viking age. The ship's rectangular sail measured about 150 square metres.
The fifth ship found at Skuldelev is a small freighter, l2
metres long, 2.5 metres abeam. It was built of fir planks and may
have served as a fishing boat or a ferry.
The navigation abilities of the Viking ships have been much
discussed for many years. To investigate this problem more closely
three identical copies of three of the Skuldelev boats have over
the past decade been built under the supervision of specialised
scientists. In 1983, near Ålesund in Norway, a copy was launched of
the larger merchantman: the knarr . The copy, named Saga Siglar,
set out in 1984 on a circumnavigation of the globe with the first
part of the voyage following the ancient Viking route across the
North Atlantic to Iceland and Greenland.
The navigation tests done so far with the two copies of the
merchantmen from Skuldelev have provided us with a good background
for evaluating the sailing qualities of the freighters. On the
basis of the tests it can be concluded that already by the Viking
age a navigation standard had been achieved which fully matched
that of the smaller merchantmen at the end of the sailing ship era
shortly before World War I.
