Two fragments of waterlogged wood with two copper fasteners dating from the post-medieval period onwards.
The wood may be the remains of two planks of wood used in the construction of a ship as the planks are secured with one copper fastening and a hole is visible where another fastening may have also been used. Copper rivets are the standard method of fastening the planks to each other in clinker constructed vessels, or in the planks to the ribs or frames (Traditional Maritime Skills website, accessed September 2017). Clinker is a method of constructing the hull of a boat by fixing wooden planks so that the planks overlap along their edges. The overlapping joint is called a land. If the plank is too short for the hull, it would be necessary to extend the plank by joining with another piece of wood. Planks are also known as strakes (rubbing strake for example) so this method is also known as lapstrake. It is a very traditional method of ship construction.
Metallic fastenings followed on from tree nails (also commonly known as trunnels and trennels), which were an older method of securing two planks together using wooden 'nails'.
