The reconstructed longship Sea Stallion from Glendalough sailed from Roskilde to Dublin and back in the summers of 2007 and 2008, with an international volunteer crew of 60 men and women. The first results of this extraordinary voyage on the track of the Vikings are now available. This volume gives an account of the methodological considerations behind a trial voyage as experimental archaeology. The course of the voyage is mapped out historically, based on the weather conditions and the waters navigated. The book provides a fascinating insight into the issues involved in the reconstruction of the ship's steering system, a description of life on board and the experiences of handling a longship, including its travel speed and sailing capabilities.
