The Mediterranean Lateen Sail in Late Antiquity

The Mediterranean lateen sailing rig has been studied since the early-to-mid-20th century. Recently-published depictions of sailing vessels rigged with lateen and settee sails, dating to the late-antique period, allow some of the principle characteristics of that rig to be established. This allows comparison with lateen- or settee-rigged vessels from both earlier and later periods. The sailing rigs depicted on other vessels can be identified and the level of technical continuity between the late-antique and medieval Mediterranean addressed. Finally it is possible to assess the extent to which the lateen sail was established in the Mediterranean by late antiquity.

The Karschau Ship, Schleswig-Holstein: Dendrochronological Results and Timber Provenance

The felling of the oak trees used to build the Karschau ship took place in or around the AD 1140s. The tree-ring curves from the oak planks from the Karschau Ship match best with site-means from Odense, a medieval town on the island of Funen, Denmark. New research being carried out by the author is allowing the determination of the provenance of ancient oak to a more local level. Through this dendrochronological research, it is now possible to differentiate between small regions of timber sources for shipbuilding, allowing a more nuanced interpretation.

关于全国造船统筹的回顾与思考

建国之初 ,百废待兴 ,全国修、造船业没有统一规划、统一安排的矛盾还不突出。但 2 0世纪 60年代以后 ,问题逐渐尖锐、突出 ,为此 1 963年国家计委和李富春副总理分别在给中央的报告中涉及此问题 ,希望能统筹解决 ,但因报告中没有具体解决措施 ,造船统筹工作没有启动。后经历了六机部统筹时期、粟裕抓造船统筹时期、船舶总公司统筹时期和机电部统筹时期 ,各时期虽均取得一定的进展 ,但并没有真正解决根本问题。造船统筹滞后的原因主要是 :相关法律、法规不健全 ,没有能统揽全行业的有权威性的行政管理机构 ,缺乏航运和造船协调发展规划等 ,因而实施船舶工业的宏观管理 ,建立宏观调控体系非常必要     

鱼群的洄游与南海早期先民

鱼群季节性洄游对渔民的生活无疑是有很大的影响,但在先秦时期这种影响并没有直接导致先民的季节性居住。一方面是南海北岸及海岛海湾附近一年四季都不乏食物资源,无需作季节性迁移;另一方面是当时的生产力水平还达不到为追随几种经济鱼类而长期在船上随季节移居的要求。     

Bahamian Ship Graffiti

In the Age of Sail the Bahamas was on major routes between the Americas and Europe. Bahamians developed a way of life using their location to advantage. Ship graffiti are the first archaeological evidence of Bahamian shipping activity. The graffiti are unique in the region, being incised into a variety of stone surfaces, and probably other surfaces which have not survived. Images depict locally-built vessels such as sloops and schooners as well as larger, ocean-going ships. Graffiti locations are predominantly associated with people of African heritage and lower socio-economic status. Details suggest artists were familiar with ship construction and rigging.
