The Indian Ocean - Michael Pearson [155]
Certainly navigation and map-making improved dramatically in the nineteenth century, so that in the terms used by Edward Said the Indian Ocean was constructed and 'known' by foreigners: knowledge and power coexisted in a symbiotic relationship. The British spent much time and effort on making accurate charts. Captain William Owen on behalf of the British Admiralty spent an arduous five years, 1821–26, in two ships charting the East African coast. The results of these and other expeditions were published in the many Admiralty Guides which are one illustration of the technological superiority of the Europeans at this time. Here and elsewhere they was a strong connection between this advance and the displacement of local traders and ships. In the case of the maps and guides, they obviously made navigation safer for those who could use them, which obviously was mostly Europeans. Local craft seldom had anyone on board who could read them, and also did not have the navigational equipment needed to take advantage of their directions.
These charts and books were one way in which Europeans were able to overcome or at least ameliorate the effects of the deep structure elements I outlined in the first chapter of this book. Many of them no longer acted as iron constraints on what ships and people could do at sea. The monsoons, a strait jacket for millennia, now became largely irrelevant when confronted by steam ships. Poor harbours, or no harbours at all, were overcome by British engineers. Even distance was transformed by steam ships and the Suez Canal. As a capsule example, consider that even in the 1830s a return voyage from England to India took two years. By the 1850s steamers had cut this down to two to three months, and communication within a day became possible with the telegraph in the 1870s.
We have written extensively in previous chapters about the perils and risks associated with wind-propelled ships. Ships of whatever size which depended on the wind had obvious disadvantages, at least in economic terms, if not in aesthetic. They needed very large crews, so that the dhows of the western ocean were often overcrowded with crew, passengers, and traders all mixed together in each other's way, and indeed the distinction between the three was by no means clear cut.
In the first half of the nineteenth century there was considerable variation around the ocean. In some areas, such as in the Gulf and off southern Arabia, local ships did well. In other areas a pronounced dualism developed at this time, and this is before the major impact of steam ships. British sailing ships dominated long-distance trade,
