A folded sail was found stowed in the hold of the Swedish‐registered merchantman Jeanne‐Élisabeth, which ran aground off Montpellier in a storm in 1755. Surviving sails from any period are rare. The structure of the recovered portion of sail and its associated cordage is described and discussed in the context of differing traditions and technological evolutions of the period. Recovery, recording and initial conservation techniques are discussed in an appendix . © 2011 The Authors  相似文献

A review of the Khufu I vessel (c.2566 BC) and contemporary Egyptian iconography (c.2613–2345 BC) suggest this vessel was originally fitted with six pairs of quarter‐rudders, instead of one pair. Furthermore, quarter‐rudders may have been mounted on knob‐shaped thole‐pins, instead of crossbeams. The iconography also suggests that each quarter‐rudder was fitted with a loom‐line and specialized grommet, and rowers may have used a similar system to mount their oars. Finally, a recently published depiction of Sahure sailing a boat may show an anchor secured on the stern deck. © 2011 The Author  相似文献
