In the 1980s they built a replica of this boat which sank on it's maiden voyage, they raised it and sailed it carefully for a short while before it sank again. This lead some archaeologists to question whether ships in burials were actually working ships or whether they were constructed especially for the burial. The current project have scanned each timber and used computer modeling to reconstruct models of the ship, they now think that when archaeologists reconstructed the ship in the museum the shape was effectively altered making it unseaworthy. Testing of the new model in a wavetank suggests that it will sail very well.
This photo was taken 18th October and shows the current progress on the ship. The occasion was a visit by the Norwegian president, he was apparently quite skilled at hewing with an axe. I hope to have lots of photos to share of the worksite and maybe will return next year when the project is completed.
