Tradition says "longboats". These are usually pictured as having dragon' s head prows (at the front) but there's not a lot of evidence for that. They were shallow draught fairly flat bottomed boats well suited to going up-river as well as crossing the North Sea. Take a look at at the Jorvik, and York Archeologiacal Trust, websites.
