A contemporary chronicle recorded the moment with a brief entry: The ravages of heathen men miserably destroyed Gods church on Lindisfarne, with plunder and slaughter. The heathen men were Vikings, fierce warriors who sailed from Scandinavia and bore down on their prey in Europe and beyond in sleek, fast-sailing ships. In the centuries that followed, the Vikings vessels carried them deep into Russia and as far south as Constantinople, Sicily, and possibly even North Africa. They organized flotillas capable of carrying warriors across vast distances, and terrorized the English, Irish, and French coasts with lightning-fast raids. Exploratory voyages to the west took them all the way to North America.
The Vikings explosion across Europe and Asia and into the Americas was the result of the right combination of tools, technology, adventurousness, and ferocity. They came to be known as an unstoppable force capable of raiding and trading on four continents, yet our understanding of what led up to that June day on Lindisfarne is surprisingly shaky. A recent discovery on a remote Baltic island is beginning to change that. Two ships filled with slain warriors uncovered on the Estonian island of Saaremaa may help archaeologists and historians understand how the Vikings warships evolved from short-range, rowed craft to sailing ships; where the first warriors came from; and how their battle tactics developed. We all agree these burials are Scandinavian in origin, says Marge Konsa, an archaeologist at the University of Tartu. This is our first taste of the Viking era.
Between them, the two boats contain the remains of dozens of men. Seven lay haphazardly in the smaller of the two boats, which was found first. Nearby, in the larger vessel, 33 men were buried in a neat pile, stacked like wood, together with their weapons and animals. The site seems to be a hastily arranged mass grave, the final resting place for Scandinavian warriors killed in an ill-fated raid on Saaremaa, or perhaps waylaid on a remote beach by rivals. The archaeologists believe the men died in a battle some time between 700 and 750, perhaps almost as much as a century before the Viking Age officially began. This was an era scholars call the Vendel period, a transitional time not previously known for far-reaching voyagesor even for sails. The two boats themselves bear witness to the tremendous technological transformations in the eighth-century Baltic.
In 2008, workers digging trenches for electrical cables in the tiny island town of Salme uncovered human bones and a variety of odd objects that they unceremoniously piled next to their trench. Local authorities at first assumed the remains belonged to a luckless WWII soldier, until Konsa arrived and recognized a spearhead and carved-bone gaming pieces among the artifacts, clear signs the remains belonged to someone from a much earlier conflict. Together with a small team, Konsa dug a little deeper and soon found traces of a boats hull. Nearly all of the crafts timber had rotted away, leaving behind only discolorations in the soil. But 275 of the iron rivets holding the boat together remained in place, allowing the researchers to reconstruct the outlines of the 38-foot-long craft.

(8,170 posts)on page 2 the author says, "The craft had a keel, an element critical to keeping a sailing ship upright in the water."
That is wrong, very, very wrong.
But still an interesting read.

(60,011 posts)I am a blank slate when it comes to boats and sailing, would appreciate the information.
Are you saying the craft did not have a keel?
or
saying a keel is not a necessary element in a sailing ship?
or
a keel in a sailing ship does not serve to keep the craft upright?
The keel has 2 functions, structural and navigational.
Structurally it serves as the backbone of the vessel from which everything else is built. It keeps the boat rigid so that it doesn't snake through the water nor does it hog or sag

Navigationally it increases the area resisting the sideways movements caused by wind on side or sails, because there is this resistance sailboats can use side on winds to still go forward. The more lateral resistance there is the more a sailboat can head into the wind (sail close to the wind).
Boats are actually kept upright by the shape of the hull, crudely put a plank does not float narrow side down.
On Edit: Boats are actually tipped by the action of wind on sail and water on keel.
