Dugout canoe by Hanson

The dugout Hanson ( english Hanson logboat , Shardlow logboat 1 ) is a Bronze Age dugout of oak, in a 1998 gravel pit in Shardlow, south of Derby in Derbyshire in England was found. The boat is in the Derby Museum and Art Gallery . It was in an old arm of the Trent .

The boat was slightly damaged by machinery before its importance was recognized. Since it was very heavy, the boat, which is around 11.0 m long (originally around 14.0 m long) was sawed into 1 m long sections for transport. The wood was freeze-dried after being soaked in polyethylene glycol (PEG 200, then PEG 3400) for 18 months by the York Archaeological Trust . This is a standard method for wet wood preservation. In 2011, however, it began to disintegrate again because the wood was largely mineralized. Excavation and conservation cost £ 118,000.

The boat made of an oak trunk , the stern missing, was with two radiocarbon dates to 1440-1310 cal. BC . so dated to the Middle Bronze Age It is about as old as the Dover boat and a little younger than the Ferriby Boats from Yorkshire . The boat was filled with Bromsgrove sandstone quarried near Kings Mills . The stones should keep the dugout canoe under water over the winter.

A second Bronze Age wooden boat (Shardlow Logboat, Logboat 2), dated between 1600–1420 BC (95.4% probability), was discovered in 2003 in the same gravel pit and preserved in situ
