Restoration work on the Cutty Sark, a 19th Century tea clipper, following a devastating fire, is nearing completion.
It is time for engineers to lift the 900-tonne vessel into its final position ahead of its reopening to the public in spring 2012.
The full story of the conservation project in Cutty Sark: National Treasure was shown on Friday 3 February on BBC Two, and is now available to view on the BBC iPlayer.
