Abstract:

Abstract1997 was an important year for Russia's Northern Sea Route (NSR) in terms of foreign interest. The first full transits of the NSR by western merchant ships were made. The International Northern Sea Route Programme (INSROP) continued into phase 2 of its research projects, and planning proceeded for a European Union-sponsored demonstration voyage to the Ob' River. The nuclear icebreaker Arktika returned to Arctic operations, while two icebreakers were removed from polar service. Information about the NSR became more widely available with the distribution of an English translation of a navigation guide. Winter operations continued in the Kara Sea, albeit reduced, and a limited number of summer voyages to Russian Arctic ports originated from the Pacific rim. RADARS AT synthetic aperture radar images of sea ice along the NSR were used for the first time during several demonstration voyages.

Abstract:

Abstract Main problem for scheduling vessel transit voyages through the Northern Sea Route is the difficulty in predicting distribution of ice boundaries in regions that cannot be overcome by individual ice classes of vessels. Scheduling of voyage is related to speed that vessels can develop and moment of time when vessels will be able to commence and complete passage safely through areas that are main obstacle and are blocking longest transit passage through the Northern Sea Route. This applies to voyages carried out by vessels navigating on their own and with support of icebreakers. Additional problem is lack of consistency of content of maps of ice cover, which can be used for vessels voyage planning through areas where ice cover occurs. Results of this research on influence of uncertain information related with time window of conditions favorable for navigation of vessels of different ice classes on schedule of theirs voyage on example of summer navigation season 2017 are presented in this work.

Abstract:

The State of Indonesia is a country which is according to cultural history and in the days of the kingdom is a maritime country. The country of Indonesia with the largest islands covers the largest sea, the largest island, and the second longest beach in the world. On this basis, Indonesia currently has a modern port as well as a port for people's voyages. People's voyages are generally identical to traditional wooden boats operated by natural sailors with simple management (Law No. 17/2008 on the voyage of articles 15, paragraphs 1 and 2). The demands of global business are causing people's shipping today to be marginalized.Some problems in the voyage of the people include the procurement of the shipping fleet is hampered by the difficult supply of logs, so it needs to look for other alternatives. Another problem is the guarantee of safety and good service from the voyage of the people The government plans to build the People's Port. This port will be built with a good security system. The sailing of people with the zone of its own. People's voyages are still needed, because remote areas that are not crossed by large auto ships are still dependent on small ships such as KLM or PLM. In addition, there is a dock that can not be enclosed by iron vessels or shallow harbors. The voyage of the people can overcome it, thus helping national transpotation.Indonesia as the largest archipelago country still requires the voyage of the people as one mode of inter island transportation. The Government is committed to memordenisasi and improve the safety and security of people's shipping by still considering local wisdom. Another problem is the guarantee of safety and good service from the voyage of the people.

Abstract:

The opening of arctic routes provides a new option for international navigation ships. The correlation between ship movement characteristics and ice conditions should be known, which will help ships adapt to the polar waters. Based on the voyage data and sea ice manual observation data of the ‘XUE LONG’ ship’s six voyages in polar waters, a correlation analysis model of ice conditions and ship movement characteristics was established in this work. First, the ship movement characteristics in polar waters were analyzed, such as the distribution characteristics of ship speeds, courses, and variation characteristics by using the descriptive statistical analysis method and data visualization analysis method. Then, by using multivariate correlation analysis and univariate controlled correlation analysis methods, the correlation between movement characteristics and ice conditions, such as ice concentration and thickness, and the correlation between different ice conditions themselves, were quantitatively analyzed. The result shows that the correlation analysis model of ice conditions and ship movement characteristics is reliable and effective and can obtain quantitative correlation analysis results. On the one hand, sea ice thickness has almost no significant correlation with ship movement characteristics, excluding the influence of sea ice concentration. On the other hand, excluding the influence of sea ice thickness, sea ice concentration is still significantly correlated with the absolute value of speed, speed variation, and course variation. The conclusions of this work have important reference significance for polar scientific investigations, commercial ships’ voyages in icy waters, and ships’ designs for icy waters.

Abstract:

This paper realizes the simultaneous optimization of a vessel’s course and speed for a whole voyage within the estimated time of arrival (ETA), which can ensure the voyage is safe and energy-saving through proper planning of the route and speed. Firstly, a dynamic sea area model with meteorological and oceanographic data sets is established to delineate the navigable and prohibited areas; secondly, some data are extracted from the records of previous voyages, to train two artificial neural network models to predict fuel consumption rate and revolutions per minute (RPM), which are the keys to route optimization. After that, speed configuration is introduced to the optimization process, and a simultaneous optimization model for the ship’s course and speed is proposed. Then, based on a customized version of the A* algorithm, the optimization is solved in simulation. Two simulations of a ship crossing the North Pacific show that the proposed methods can make navigation decisions in advance that ensure the voyage’s safety, and compared with a naive route, the optimized navigation program can reduce fuel consumption while retaining an approximately constant time to destination and adapting to variations in oceanic conditions.

Abstract:

This article analyses the first three English ventures into the Red Sea from 1608–1614 under the auspices of the East India Company's fourth, sixth, and eighth voyages. These ventures experienced a variety of disasters from shipwreck, captivity, mutiny, and the deaths of crewmembers. The sixth voyage, commanded by Henry Middleton, experienced the worst of the disasters. Middleton ran afoul of Ottoman officials in the port city of Mocha in Yemen and was taken in chains to the regional capital of Sana'a. He eventually escaped and returned to the Red Sea to seek revenge by blockading the port and committing acts of piracy. Middleton's actions reverberated back to Istanbul and London, where the main point of contact between England and the Ottoman Empire, the Levant Company, was forced to deal with the fallout in order to maintain its presence in the Sultan's dominions. The article argues that, despite the failures of these voyages, they reveal a great deal about the nature of overlapping jurisdictions and sovereignty in the early modern world, and furthermore they provide an important window into the evolution of corporations into entities capable of putting together empires amongst these disparate jurisdictions.

Abstract:

In an earlier study I described the material on Morocco, the Saharan coast, sub-Saharan Africa, and the neighboring Atlantic islands, which appeared in Richard Hakluyt's collection of English voyages, in its two editions of 1589 and 1598-1600. Up to his death in 1616 Hakluyt continued to collect additional material for an intended third edition. This material passed to Samuel Purchas (1577-1626), an Essex and then London clergyman, who had already begun to collect and publish voyage material on his own account.In 1613 Purchas published his Pilgrimage, which appeared again in progressively enlarged editions in 1614, 1617, and 1626. Pilgrimage presented a synthesis of contemporary knowledge of the outer continents, based on accounts of voyages and journeys to and descriptions of exotic lands, some of them published, others from manuscripts collected or inspected by Purchas, the whole notionally organized as a review of religious practices throughout the world. Although Pilgrimage cites a vast range of sources and sometimes quotes from them, the work is basically a summarizing of the sources in Purchas' own words. Of much greater interest, therefore, is Purchas' other major work, his masterpiece, his Pilgrimes, which appeared in 1625 in four very large volumes running to some 4000 pages. Pilgrimes is a collection of sources, on the model of Hakluyt's collection, though Purchas more frequently presents his sources in cut versions. The material covers voyages and journeys to all parts of the known world, and is not limited to English voyages--the major limitation being only the extent of material Purchas could lay his hands on.

Abstract:

There are long-standing and ongoing concerns about the welfare of animals in the Australian live export trade by sea. However, scrutiny of animal welfare on board vessels is generally hindered by a lack of independent reporting. Cattle voyages from Australia to China have concerned animal welfare advocates due to their long duration and lack of consistent veterinary oversight. In April 2018, following a media exposé of animal cruelty and declining public trust, the Australian government installed Independent Observers on some live export voyages. Summaries of Independent Observer (IO) reports by the Department of Agriculture and Water Resources (DAWR) provided a new and independent source of information about management of animals in the live export trade. The IO summaries on live cattle export voyages to China for the period July 2018 to December 2019 (n = 37) were reviewed. The IO summaries detailed voyages that carried 147,262 slaughter, feeder or breeder cattle which included both dairy and beef breeds. The long-haul voyages averaged 20 days in duration, generally departing the ports of Fremantle and Portland and discharging at ports in northern China. Key animal welfare risk factors identified in the IO summaries included: hunger, thirst, exposure to extreme temperatures, poor pen conditions, health issues, absence of veterinarians, rough seas, poor ship infrastructure, mechanical breakdown and mismanagement at discharge.

Abstract:

In the article there is considered the problem of the impact of factors of the long voyage on the body of sailors-operators of logical and sensory profile of the activity. The aim of the study is to estimate indices both of body functions and performance of marine specialists operators of video display terminals during the long voyage. The experimental group included 27 crew members from the command, the Navigator group, group of locations and communications, professionals exploiting videodisplay terminals. Functions of operators bodies during the period 65-day voyage were studied with the use of the techniques of the assessment of indices of the subjective status, cardiorespiratory, central nervous system and physical performance. There were established adverse changes in the functional state of the organism, pronounced by the decline in levels of conditioned-reflex activity, the exertion of the cardiorespiratory system at rest and in the deterioration of physical performance from the second month of sailing and persisting until the end of the voyage, despite the optimal level of factors of the habitability at the ship. The leading adverse factors included the decrease of the motor activity by 2.5 - 3 times if compared to pre-trip levels and the intense operator activity. This necessitated the development of manners and means of the preservation of the occupational health of seafarers-operators in long voyages, as well as the improvement of the hygienic regulations of the conditions of their professional activity in the courts.

Abstract:

Growing interest in finding the optimal route through the arctic ocean, and sea ice concentration is also emerging as a factor to be considered. In this paper, an algorithm to calculate the sea ice concentration was developed based on the images taken during the Arctic voyage of the Korean icebreaker ARAON in July 2019. A sea ice concentration calculation program was developed using the image processing functions in open-source image processing library, called OpenCV. To develop the algorithm, parameter studies were conducted on red, green, blue (RGB) color space and hue, saturation, value (HSV) color space, and k-means clustering. To verify the algorithm for sea ice concentration calculation, it was applied to images taken during Araon’s Arctic voyages. Lens curvature and view point were corrected through camera calibration. To improve the accuracy of sea ice concentration calculation, a binarization model based on random forest was proposed. A parameter study for training image numbers and tree numbers was conducted to establish the random forest model. The calculated sea ice concentrations by random forest and k-means clustering were compared and discussed.

Abstract:

Eduard Dallmann, of Blumenthal on the lower Weser, went to sea at the age of 15 in 1845. He took command of his first ship, the whaling vessel Planet, in 1859 on a whaling voyage to the sperm whaling grounds in the Pacific and to the Sea of Okhotsk. Over the period 1864–66 he commanded the Hawaiian vessel W.C. Talbot on trading voyages to the Alaskan and Chukotka shores of the Bering and Chukchi seas. On 17 August 1866 he sighted and landed on Ostrov Vrangelya (Wrangel Island), a year prior to its sighting by Thomas Long, credited by many with the first sighting. For the following three years he commanded the whaling ship Count Bismarck on a whaling cruise to the tropics, the Sea of Okhotsk, and the Bering and Chukchi seas. In 1873–74 he made the first Antarctic whaling voyage aboard Groenland, and discovered and charted the west coasts of Anvers, Brabant, and Liège islands, as well as many smaller islands and straits including Bismarck Strait. He spent the 1875 whaling season as expert consultant, still aboard Groenland, on the Davis Strait and Baffin Bay whaling grounds. Then, to complete his career in polar waters, from 1877 to 1883 he made annual attempts to haul freight to the mouth of the Yenisey River, to be exchanged for grain cargoes brought down that river by barge. Of the seven attempts, only four were successful, the rest being foiled by ice conditions in the Kara Sea, and on the basis of this record, Baron von Knoop, the Russian entrepreneur who was financing the operation, decided to cut his losses. This ended Dallmann's career in polar waters.

Abstract:

The success of the ship's voyage depends on accurate and up-to-date meteooceanographic information about the sea areas crossed. This article demonstrates the benefits of establishing routes appropriate to the knowledge of the actual meteo-oceanographic conditions, which will ensure: time and fuel savings, increased safety of the vessel, crew, and mission success. The modelling of navigation and hydrometeorological conditions in the coastal and harbour area of Constanta Agigea is necessary to know the efficient execution of the voyages of an integrated multi-sensor maritime platform, intended for real-time intervention for disaster risk management in Romanian coastal and harbour areas.

Abstract:

Abstract The navigation on the Black Sea raises some specific issues that need to be considered, to ensure maximum safety conditions for the ship, crew, and cargo throughout the voyage. Under the current conditions of the global maritime market having a high degree of concurrency, respectively the problem of reducing fuel consumption and reducing the time needed for performing various voyages, especially in crossing the ocean on different routes, is particularly important for ship owners. The economic effect is determined by converting this time into the corresponding cost price, fuel consumption having the main percentage; to these is added the benefits increase by reducing the period of undertaking the transport contract.

Full text

Abstract:

Metabolic responses to persistent inappetance were studied in sheep transported by sea from Australia to the Arabian Gulf in May and August. In the May voyage inappetant sheep successfully mobilised fat and generated ketones to supply energy and few died (0.83%). However, in August, inappetant sheep failed to mobilise fat for more than a few days and the death rate was much higher (3.27%). The causes of death were similar in both voyages; approximately 65% of the deaths were due to inanition. We postulated that in May, sheep coming from dry pastures were nearing the end of a cycle of liveweight loss and were metabolically adjusted to using adipose reserves for energy. However, in August, sheep had entered a period of liveweight gain on green pastures and were consequently unable to sustain lipolysis for energy supply when inappetant.

Abstract:

This paper looks at gastronomic identity in the age of global labor migrations. Focusing on the nineteenth-century indentured labor voyages from northern India to the sugar colonies in the Caribbean and Asia-Pacific regions, it highlights the sea voyage as both a social setting and a mirror back onto colonial society. The space of the indentured labor ship serves as an innovative site for understanding the political, cultural, and economic dimensions of historical labor movements, through which colonial politics and gustemic identities were negotiated. An analysis of the food provisions and other culinary items that British colonial officials provided to indentured workers during their journeys situates the “taste” of laborers in colonial feedings.

Abstract:

Shipping plays a very important role in the movement of most goods in the world. Ships are a means of transport used to transport goods at sea. Every day, there are many ships moving back and forth between different seas at a high frequency. Each ship’s voyage can be full, low-load, or no-load. Using ballast water is a long-standing solution used to balance and stabilize ships during voyages. Ballast water is taken into the ship and discharged anywhere in the sea. This means that the organisms in the ballast water can also migrate to any part of the sea. There are beneficial organisms and harmful organisms for the ecosystem in the waters they are brought in. Organisms that grow unprofitably will destroy the stable ecology of the seas they reach. To solve this problem, it is necessary to have appropriate legal policies and solutions to treat ballast water. This short review presents current regulatory policies and solutions for ballast water treatment. Some challenges and prospects for future regulatory policies and solutions for ballast water treatment are also outlined.

Full text

Abstract:

This article explores thejurimetric significance ofa phrase orformula, “kenning be kenning and course be course”, used in maritime law texts and disputes in late medieval and early modern Scotland and England. On open sea voyages, knowing one's position and using that knowledge to plot the next stage of the trip depended, not only on topographical knowledge ofcoasts and theirfeatures, but also on knowledge ofthe “kennings” (sightings, or the distances between two visible points of coastal topography) encountered on coastal voyages or at the end ofa sea-going passage, as well as knowledge ofthe “courses” to be sailed in the latter case. Knowing howfar a vessel had travelled was also crucial in actionsfor payment offreight pro rata itineris orfor payment of wages. The several versions of the Judgments of the Sea used in northern Europe stated what the law was in such disputes, but the remedies given were dependent on a calculation ofdistance in either kennings or courses. The Scottish contextfor this practice is explored in detail.

Abstract:

Relevance. The main thing in the prevention of acute odontogenic infection in sailors during long voyages is the full implementation of the pre-voyage sanitation of the oral cavity, which provides for the elimination of chronic foci of odontogenic infection.The aimof the study was to identify chronic foci of odontogenic infection in sailors after the completion of their prevoyage sanitation of the oral cavity and before going sailing.Material and methods. Dental and X-ray (orthopantomography) examination of 169 men aged 22 to 52 years after completion of dental treatment (oral cavity sanitation) before a long sea voyage was carried out, followed by analysis of clinical and radiological parallels to identify chronic odontogenic foci of infection, which can be a potential source of microorganisms for the development of acute odontogenic infection during swimming.Results and discussion.It was found that, despite the ongoing treatment and prophylactic work on the rehabilitation of the oral cavity with the sailors in the pre-voyage period, in 30.4-77.2% of cases they retain chronic foci of odontogenic infection during a long sea voyage, which can become the cause of the development of acute odontogenic infection. For the qualitative detection of chronic odontogenic foci of infection, it is necessary to supplement the dental examination of sailors in the pre-voyage period with an X-ray examination, which will allow timely identification and elimination of chronic odontogenic inflammation of the maxillary sinuses, as well as chronic periapical and periodontal foci of odontogenic infection.

This article discusses safety and economic issues of sea transport during transit voyages of a vessel across the North Sea Route (NSR) in the Arctic Ocean. The main obstacles to shipping and threat to vessels are the regions of ice occurrence and, in particular, clusters of ice with high and very high concentration, thickness and hummocking occurring each year in the same places, which are called ice massifs. Speed of vessels has the greatest impact on the economy of transit voyage. The safe speed of vessels, as a means of transport that ensures trouble-free navigation of the vessels depends on ice conditions. Until now, the concept of safe speed has not been precisely defined. Also, the impact of speed of the vessel in certain ice conditions on overcoming the ice and the risk of damage to vessel has not been precisely defined. Issues of direct and potential costs of vessel’s safety, damages and consequences of damages in ice were also not fully considered. The author analyzed the above relationships on the example of the first commercial vessel transit voyage through the NSR and obtained generalized results that can be applied to the initial, general and tactical route planning till 10 days - 6 months ahead and transit schedule of a vessel between Europe and the Far East ports via the Northern Sea Route. The presented method should increase safety and economy of sea transportation in areas covered with ice.

ABSTRACT This article introduces the ongoing project Moravians@Sea, which visualizes the spatiotemporal dimensions of the Moravian Atlantic crossings by presenting the transcriptions of the diaries on the transatlantic voyages as a “visualized source edition” and contextualizing them with further source material of other projects. This makes Moravians@Sea part of a cross-project storytelling of Moravian biographies. In view of the accumulative character of the portal, it can be understood as a metaportal of research on Moravian self-narratives. The visual conceptual principles of the website are explained.

Abstract:

Abstract The work discusses possibility to make transit voyages of vessels without ice strengthening on the Northern Sea Route (NSR). Exist many uncertainties for it. They are related to hydro-meteorological conditions, mostly to ice cover on the Russian Arctic. Ice conditions are under dynamic changes in time and space. Is hard to precisely predict ice conditions now, in the time range of one month and so on. Statistical historical data of daily changes same like yearly changes show a considerable scatter of the data. The author analyzed number of ice-free days of particular seas of the NSR in the latest eight years. The results of this work may be used for estimation of time frame (time window) for transport of cargo on the NSR by means of vessels without ice strengthening. The statistical presentation of ice-free days data was used in the work to develop decision supporting method related to planning vessel voyage including ice-free time frame on particular seas of the Northern Sea Route.

Abstract:

AbstractCondensation inside marine containers occurs during voyages owing to weather changes. In this study, we define the condensation probability along one of the major routes for container ships between Asia and Europe. First, the inside and outside air conditions were measured on land in Japan, and a correlation analysis was conducted to derive their relationship. Second, onboard measurements were conducted for 20,000 twenty-foot equivalent unit (TEU) ships to determine the variation in outside air conditions. Complicated patterns of weather change were observed with changes in latitude, sea area, and season. Third, condensation probability was estimated based on a multi-regression analysis with land and onboard measured data. The maximum condensation probability in westbound or eastbound voyages in winter was found to be approximately 50%. The condensation probability estimation method established in this study can contribute to the quantification of cargo damage risks for the planning of marine container transportation voyages.

Abstract:

During James Cook’s second voyage of discovery, a young Tahitian by the name of Omai (1751–1780) was taken aboard the Adventure, one of the two ships of this expedition. Omai travelled to England, where he was introduced into the British Upper Class and much admired as a living example of a noble and pure South Sea islander in tune with Mother Nature. Omai became accepted in the highest society circles, was painted by several great artists of the time and became part of the collective hype surrounding James Cook’s voyages of discovery and the new experiences with non-European cultures. This paper compares available scientific literature on this topic and aims to analyze the role of Omai as a historical figure and as the personification of the idealized European concept of the noble savage.

Abstract:

Observations were conducted from the Research Vessel “Akademik Mstislav Keldysh” in the Drake Passage, vicinities of the Antarctic Peninsula, Scotia Sea and the northern part of the Weddel Sea during two voyages in January–early March 2020 (the vessel trip number 79) and during the single voyage in January–February 2022 (trip number 87). Data allow to evaluate the number of the most abundant sea mammals in the area near South Shetland Islands, Scotia Sea and Powell Basin. Observation area of 2022 in the Antarctic were located in about 150 km eastwards of the area of 2020. The area under survey of a little bit greater than 343 th. square km in January-February 2020 held approximately 1200 Humpback Whales (Megaptera novaeangliae) and 2800 Fin Whales (Balaenoptera physalus). In 2022 this area held approximately 2500 Fin Whales and again 1200 or more amount of Humpback Whales. Numbers of the Antarctic Fur Seals in each season here assessed approximately 2000-3000 animals. Type of distribution of these two whale species along the vessel track pointed on the absence of food competition either within or between these species during Antarctic summers of 2020 and 2022. It was possible to evaluate the total numbers of the Antarctic Fur Seal (Arctocephalus gazella), however this evaluation appeared to be less precise than the same ones for Humpback Whales and Fin Whales.

Abstract:

Prediction of fuel consumption rate level of a vessel per voyage posed to be a challenge under uncertainties. In such uncertain conditions, revealing of fuel consumption rate levels of the fleet of vessels is deemed imperative to ensure effective and efficient operations of the vessels per voyage. Therefore, development of uncertainty treatment model is necessary in this research. A combined algorithm that is made up of fuzzy rule base and utility theory methods is incorporated in the investigation of the fuel consumption rate levels of marine vessels. The mechanism of the algorithm is used to capture and combine all the important parameters that determine the fuel consumption rate level of each marine vessel. The workability of the model is demonstrated. The produced results revealed that the combined algorithm can support estimation of the fuel consumption rate levels of marine vessels and show which vessel is better than the other. Based on the results of this article, the management and crew of a marine vessel are equipped with the necessary decision support tool to optimize, implement and manage improvements on the performance characteristics and fuel consumption rate of their marine vessels during voyages.

Abstract:

During the course of a voyage of discovery to Australia the zoologist François Péron, aided in its early stages by the geologist Louis Depuch, took regular measurements of air and water temperatures at the surface of the sea and, on four occasions, at various depths in the equatorial parts of the Atlantic Ocean. The data they collected made a useful contribution to a better understanding of the oceanic environment. A comparison of their findings with results obtained on the voyages of Captain Phipps to northern latitudes and by scientists on Captain Cook’s second voyage in waters of the South Pacific Ocean, enabled Péron to declare that temperatures in the world’s oceans, at all latitudes, decreased with depth. Considering the implication of this trend to ideas on the temperature in the interior of the Earth, Depuch sided with scholars who believed that its centre was hot, while Péron, relying on his own observations and those of other investigators, tended to favour the cold Earth theory, but was hesitant in reaching a firm conclusion.

Abstract:

By 8000 B.P., sea-mammal hunting and open-sea voyages were established at Eel Point, San Clemente Island, California. The early inhabitants of Eel Point depended heavily on sea-mammal hunting and shellfish collecting, rather than the intensive fishing that developed during the Late Holocene along the Southern California coast. Eel Point technological capabilities rivaled those of Late Holocene groups such as the Chumash Indians, including the ability to fabricate sophisticated watercraft. These data question traditional models of progressive maritime cultural development in coastal Southern California, and reveal the need for more empirical methods of assessing the seafaring capabilities of ancient maritime populations.

Abstract:

Relatively little has been reported about the seabirds of Gough Island, central South Atlantic Ocean, from autumn and winter. We report ad hoc observations on the abundance, phenology and moult of seabirds at Gough Island from March to June 2021, and during the voyages between the island and Cape Town, South Africa. At least 43 species of seabirds were recorded: 1 penguin, 8 albatrosses, 5 southern and 1 northern storm petrel, 22 petrels and shearwaters, 1 gannet, 3 terns and 2 skuas. The results are presented as an annotated species list as well as a daily log of species for the voyages to and from the island. More species were seen per day at sea in June than in March, but fewer individuals were recorded in oceanic waters, mainly due to the large numbers of Great Shearwaters Ardenna gravis in March.

Full text

Abstract:

This article uses evidence from the English High Court of Admiralty to examine the problem of mutiny and indiscipline among seafarers in the transatlantic trades during the 1680s and 1690s. It focuses on a venture of 1688, which is of particular interest not only for the light it sheds on maritime conditions, but also because it involved Daniel Defoe, a young and ambitious trader who was trying to establish a commercial opening in Chesapeake Bay. The article contextualizes this previously unknown venture, relating it to the development of the tobacco trade and its dependence on an expanding market and widening patterns of consumption. The failure of the voyage, in association with other business problems, had serious consequences for Defoe, leading to bankruptcy in 1692 and his withdrawal from direct involvement in overseas trade. Against a broader background of other voyages, the legal testimony heard by the court draws attention to the wider problem of mutinous conduct at sea. These cases were provoked by a range of grievances including pay, labour conditions and discipline. Repeatedly they raise questions about the conduct of masters at sea, including their rights and responsibilities. At the same time, the article argues that the upsurge in mutiny and indiscipline at sea, while revealing the inexorable tension between pay and productivity, also exposed deeper issues regarding seafaring custom and contract.

Abstract:

There is no More Sea Power. What Kind of Awe can a Fleet or an Aircraft Carrier inspire in the Nuclear Age, Whose Blasts have given a new character to military majesty and sublimity and whose marine vehicles are hidden beneath the waves? Nor do the ocean-girding voyages of global commerce offer a sense of majesty, the neat stacks of containers rising high above the decks being mere floating versions of the endless stacks at the prosaic, crane-filled ports of Busan, Long Beach, Elizabeth, or Singapore. The sea is full of transport, labor, and industry, but spectacle has moved elsewhere: what remains of the nautical in the visual media is the nostalgic sublimity of sinking ships or historical reenactments of blue-water glory. As if to underscore this vacuum of hegemonic maritime power in an age of shock and awe, the pirates of Puntland and Sulu still have their way in the Gulf of Aden and the Strait of Malacca, as they have for centuries. Latter-day posturing by the epigones of interstate maritime power contenders approaches farce, as in the struggle for the Arctic, joined by Russia, Canada, the United States, Denmark, and Norway, punctuated by Russian flags at the bottom of the sea and by the specter of Danish military incursion into what Canada claims as its sovereign territory (Craciun).
