The trawl body is always a tapered section often between 10 and 40 m long. The extension piece is an untapered section normally manufactured of either one or two pieces of 49,5 mesh long nets giving a stretched length between 6 or 12 m. The codend is also an untapered section often made of double twine in order to have a better resistance against heavy wearing.
