The boats are the second largest group of motifs on the rocks. The so-called single lined boats consist of just one line (keel line) sometimes with a distinctively marked stem.
Another type is the double lined boat with a gunwale and keel line, which may continue into a stem terminating in a prow and keel extension. The gunwale and keel line are often joined with vertical lines, and many boats the hull is completely carved.
None of the boats have sails, as they were all powered by rowing. Many boats have a crew, depicted as short vertical lines, called crew lines. In some cases, certain meaningful images are depicted with arms and legs, such as the gods and shamans with their raised holy axes, lures and shields.
