Discovered in 1992 when a new 6 metre-deep underpass was being built in Dover, the Dover Boat is one of the most complete prehistoric vessels discovered in Britain. In use around 3600 years ago, it is thought to have been capable of cross-Channel voyages as well as plying along the coast of England. The boat consists of 6 oak timbers, lashed together with yew wood. Moss was pushed into the joints. The two central planks were joined with wedges, a central rail and a series of cleats. Its surviving length is 9.5 m and it is c. 2.5 m wide although its complete extent is unknown as part is still buried. The upper planks and part of the end had been removed in the Bronze Age. The boat is thought to have required as many as 18 people to paddle. It could have held a large cargo and is therefore thought to be capable of sea-travel. It was originally preserved because it was waterlogged and covered in a layer of silt. It has been conserved by replacing the moisture with a wax substance known as PEG. It is now housed in an award-winning gallery about the Bronze Age, within Dover Museum. (location accurate to the nearest 1m based on available information)
