Ancient Boats in North-West Europe [PDF ebook] 
The Archaeology of Water Transport to AD 1500

At last a paperback edition of this standard work on marine archaeology. Séan Mc Grail »s study received exceptional critical acclaim when it was first published in hardback in 1987 and it is now revised and published in paperback for the first time. Professor Mc Grail provides an authoritative survey of water transport across Northern Europe from the Late Palaeolithic to the later Middle Ages, using evidence of excavations, but also documentary sources, iconographic and ethnographic evidence. In the process he answers such key questions as How were these boats built? What sort of environment were they used in? What speeds could they achieve? and how were they navigated?
