The modern history of British deep-sea fishing begins with the railway expansion of the mid-nineteenth century. Rapid transport and the increasing use of ice as a preservative made it possible for fresh sea fish to enter the diets of the inhabitants of inland towns. Fresh sea fish was regarded as almost a luxury food before the railway age, yet by the third quarter of the nineteenth century, it had become a major protein source for the working classes of the industrial towns, and the fried-fish shop had become a working-class institution. The sea-fishing industry underwent a vast market-induced expansion. The census of 1841 enumerated only 24,000 males as being employed in fishing. By 1881 there were 58,000. If the inland consumer ever gave thought to the fishermen who supplied his table, he probably conjured up a picture of a weather-beaten village fisherman going daily to the fishing grounds to return in the evening to his waiting wife and children, bringing the silver harvest of the sea. While he had been at sea his family had busied themselves baiting lines, making and mending nets, and, in the case of the fish wives, performing their traditional function of selling the catch. Such a picture may have been broadly true of the fishing villages of Scotland, Cornwall, Northumberland or the South coast, but a feature of the second half of the nineteenth century was the creation of a new kind of fisherman who crewed the sailing trawlers of the North Sea. The expansion of the market has coincided with the discovery of the rich beds of the North Sea, and to such an extent did the North Sea trawling ports come to dominate the fishing industry that, by the beginning of the twentieth century, Hull and Grimsby were together receiving as much fish as all the remaining ports of England and Wales put together. Those who toiled on the grey North Sea were known as the “smacksmen”, and it is the extreme nature of their occupation which is the subject of this study.
