Longship
Many of this type of ship were called Knarrs. From the 9th century larger sailing ships were used for overseas trading. Many were specialized cargo ships. They were marked by having a small crew, few oars, and depended on sails for power. They had a large load capacity for a variety of cargo. An example would be the Klåstad ship. It was built in the last years of the 10th century. The ship was wrecked near Kaupang in Norway. It had a capacity of about 13 tons and a length of 69 feet (21 meters).
