Having arrived at a preferred design of a complete boat and estimated its performance, the next stage is to consider how the actual parts found were made and how the reconstructed boat might have been built. There are few direct or relevant sources about boatbuilding methods and techniques used in the ancient world except those that can be derived from incomplete or obscure literary sources and pictorial or sculptured representations, as for instance in Egypt (Figure 6.I). There are however many situations where types of construction similar to those at Ferriby have been used in recent times and a declining number where they still are. Such ethnographic par-
allels can shed useful light on features and help to elucidate methods and sequences of working which might otherwise be obscure. There is obvious scope also for experiments to illuminate this field; some have already been done, and more are projected.
