The otter trawl is a well-established and reasonably well documented bit of gear – general common knowledge says its Irish in origin, originating in freshwater loughs before making its way to English shores. Adopted in the 1880’s, it wasn’t fully utilised until the 1890’s by the surely now famous Mr Scott of Granton. If he laid claim to this invention, I have yet to find a patent for it… Nevertheless, the otter trawl became widespread within a few years.
Those that would benefit were the new steam trawlers, themselves recent additions to the fishing fleet. unlike sailing smacks, they were better able to maintain the speed that trawl doors required. Once commonplace, a multitude of variations on the trawl door and trawl itself appeared, form the functional to the fabulous. According to my database, there are 77 different patents relating to trawling between 1984 and 1914 – and most of those are just for doors. these patents are just the British ones, of course – with most of the applicants being English or Scottish. Who knows how many other patents there in European databases?
So what happened to the sailing smacks? Many simply fell into disuse, a great many were sold on to other countries, like Scandinavia. The Second World War sounded the end of the sailing smack in England and Scotland, even with the loss of vessels during that time.
