The reinforcements continue to arrive. Notice one of the boats carries both men and horses. A unique feature of the Viking longship was the fixed side rudder. The rudder was designed in such a way that it could be easily raised in shallow water, allowing the ship to be sailed up onto the beach. The rudder extended below the keel preventing the ship from drifting sideways and acted much like a modern day centre-board. The English boats have a broken gunwale whereas the Norman ships are shown with an unbroken line. The lower border depicts the fable of ‘The Hare with Many Friends’. The moral of this fable is ‘He that has many friends has no friends’.
