Les Menhirs : Trawlers are very diverse. Smaller does not measure more than 6 meters. They have a minimum power of 50 hp and can operate with only one sailor aboard. The bigger, the freezer trawlers, measure up to 150 meters. They are propelled by powerful engines of 4000 hp and employ dozens of sailors. Trawlers less than 20 meters are mostly "multipurpose trawlers" because they use as well as trawl dredge net, locker, longline .... Trawlers can operate various types of trawls: pelagic trawls, bottom trawls, beam trawls ... Most of these trawlers have a portal that allows them to practice the rear trawling, which in 1970 replaced the fishing side.
