The bow and stem of the flat bottom are bent upwards. In the bottom there are a number of cracks sealed with moss fastened with small planks on the outside. Part of the bottom was repaired by a board with pins. The boat has eight short and long frames. Seven are made from oak wood and one from alder wood.A small mast track is provided in approximately one-third of the prow stalk.
On the basis of the finds context, the boat is dated to the eleventh century.
