“…These factors must be compensated for using principles that vary according to the nature of the deterioration of the wood when found . For example: fully decomposed wooden elements, as at Sutton Hoo (Bruce-Mitford, 1975) and Snape (Bruce-Mitford, 1952); partially-decomposed wooden elements, as for example Dover (Clark, 2004) andBrigg 2 (McGrail, 1981); dimensionally-stable wooden elements, such as Ferriby 1 (Wright, 1990), Skuldelev (Crumlin-Pedersen andOlsen, 2002) and Graveney (Fenwick, 1978). To this should be added site-formation factors (such as displacement, deformation, or bending) affecting the shape of the individual elements and the general hull form to various degrees.…”
