waiting for her ship to come in the female investor in nineteenth century Sailing Vessels
The Economic History Review, 2010Co-Authors: Helen DoeAbstract:The contribution of women to the economy as investors has an increasing profile, but sources of information on women's economic activity in the nineteenth century are limited. However, shipping registers provide new avenues for exploring this largely hidden perspective. Women investors in shipping are revealed here to be more consistently active across the century with a close involvement with their investment. They were a significant factor in enabling smaller port communities to remain self-sufficient in their industry funding until the dominance of steam in the 1880s caused the Sailing vessel to become increasingly obsolete.

biogeography and dispersal of coastal marine organisms experimental studies on a replica of a 16th century Sailing vessel
Marine Biology, 1995Co-Authors: James T Carlton, Jan HodderAbstract:Observational and experimental studies were conducted on the dispersal of fouling organisms on a replica of a 16th-century Sailing vessel along an 800 km transect from Yaquina Bay, Oregon to San Francisco Bay, California. The vessel sailed between four bays at slow speeds (3.5 to 4 knots), resided in each bay for approximately 30 d, and spent 1 to 3 d in the open ocean travelling between ports. Natural hull fouling and experimental fouling panels placed on the vessel were sampled upon departure and arrival at each port. All common fouling species survived the open sea voyages between the harbors, with largely no ecologically significant changes in abundance nor significant losses in overall diversity detected. In one port the vessel settled upon the harbor floor periodically; several entrained benthic organisms were then transported 390 km to the next port. Slow-moving, fouled Sailing Vessels of relatively long port residencies may have significantly altered the distributions of marine and estuarine organisms not only globally (leading to the invasions of non-native species) but also along continental margins (leading to the alteration of aboriginal patterns of distribution). Shipping traffic may further play an important role in gene flow between isolated populations of obligate estuarine organisms, particularly those with non-planktonic larvae.

MODERATE-COST APPROACHES FOR HYDRODYNAMIC TESTING OF HIGH PERFORMANCE Sailing Vessels
2017Co-Authors: A Day, P Cameron, E NixonAbstract:This study examines the relative merits of physical testing techniques which may be used in early stage design for assessment of the resistance of high-performance Sailing Vessels. The hull chosen as a benchmark form is a high-speed hard-chine Sailing dinghy. The hull proportions and shape are typical of modern trends in skiff design, but may also be considered to be broadly similar to some high performance yacht hulls. The 4.55m hull was tested at full scale in a moderate size towing tank, at 1:2.5 scale in the same tank, and at full-scale by towing on open water. Results show the mean discrepancy in the measured resistance between the open water towing and the full-scale tank test is around 4%. The challenges of full-scale open-water testing are discussed and several improvements identified for future work. Comparison of the full-scale results suggests that blockage and depth correction for the full-scale hull in the tank do not present a substantial problem for subcritical speeds. Larger discrepancies were found between resistance from the model scale and the full scale tank tests at higher speeds; it was speculated that these discrepancies relate to the differences in the detailed geometry of the model and full-scale boat, particularly in the region of the chines.
