Havingsten fra Glendalough
In August 2008 I was lucky enough to join the crew of the Sea Stallion from Glendalough for the second leg of its return voyage to Roskilde, Denmark from Dublin. It was a once in a lifetime experience and was even related (if somewhat vaguely) to my PhD. This page has a few images from the memorable voyage as well as some links that might be of interest.
