Treenailed boat

The treenailed boat is a boat model used in Northern Europe, usually associated with Vikings but should perhaps be ascribed to Pomeranian groups. The shape and construction coincides with the sewn boats, but instead of ropes, it is assembled with wooden treenails.

As with sewn boats, it is sometimes aesthetically adorned with heads (usually elk heads) on the stern post, thus might indicate shamanism.^{[citation needed]}
