This Late Bronze Age boat was found in 1888 at Brigg beside the
River Ancholme, in north Lincolnshire, eastern England. It was
re-excavated by S. McGrail in 1973-4 and raised for preservation
at the National Maritime Museum, Greenwich.
It is dated by C 14 to c. 820-860 BC.
The remains of the boat measured 12.20m long and up to 2.7m wide.
Five oak strakes, up to 5cm thick, lying flat were stitched together
through holes in the plank edges. The stitches were of split strands
of willow (Salix sp.) over a caulking of moss and laths of hazel
Each strake had ten cleats, each with a hole through which oak
transverse timbers passed. McGrail reconstructs the boat with
a flat bottom and with the missing sides standing vertically.
O. Roberts suggests that the hull may have been rounded.
The boat may have been a ferry across the River Ancholme.
The fragmentary remains of the boat are preserved at the National
Maritime Museum, Greenwich.
