Very colorful, the Moras were related to the Scandinavian Langskips.

The "Mora" is the name given to the name and place of the place of conversion and acceptance of the sovereignty of the King of France by Rollon, Viking. With him, and his successors, Scandinavian shipbuilding was married with Franques techniques. Thus, the Norman boats were characterized by certain similarities to the Scandinavian Langskips, including the Lion or Dragon head, the folding central mast, the fixed steering rudders, but also a construction specific to these ships, with a top, a slightly higher width. They were judged to be more stable but less rapid. They were also perfect for embarking a cavalry, a strong point of the Norman army. Their average size ranged between 12 and 24 meters and they could carry 20 to 30 rowers, who were also fighters. In 1066, William the Conqueror built several hundred of these ships (nearly 900) to disembark his 15,000 warriors on the coasts of Great Britain. This episode and the ships he built are very well known to us through the very long tapestry of bayeux, which shows of the very colorful Langskips.
