The great sea expeditions of the Viking Age - The basis of the great sea expeditions undertaken by the Vikings was ship technology. The Viking ship was a piece of high technology based upon hundreds of years of development and experience. It was distinguished by its narrow keel and shallow draught. This made even the largest ocean-going warships suitable for sailing onto beaches and up rivers. Such tactics enabled, for example, the siege of Paris to be carried out in the year 885.
