Trawler Guide, Meaning , Facts, Information and Description
A trawler is a fishing vessel designed for the purpose of operating a trawl, a net that is dragged along the bottom of the sea (or sometimes above the bottom at a specified depth).Sailing trawlers were limited to trawling at depths of 55-75 meters, while modern trawlers often trawl to 900 meters, with experiments having gone even deeper. Sizes of modern trawlers vary, but range up to vessels of 2,500 to 3,000 tons.
Refrigeration machinery aboard allows trawlers to stay out for several weeks filling the hold.
During World War I and World War II, many trawlers were used as minesweepers, the activities being similar, and both the crew and the equipment aboard already suited to the task. During the Cold War, the Soviet Union often used trawlers outfitted with additional electronic gear to monitor NATO and US activities.
