Deck TypeDecked and undecked vesselsOverviewHand operated longlining can be carried out with boats and vessels of every size. Number of hooks and lines handled depends on the size of vessel, the degree of mechanisation and the size of the crew. Almost any vessel can function as a longliner to some degree; however, there are large purpose built longliners which engage in single species fisheries such as those for tuna.Vessel ClassLengthall  (LOA) PowerallTonnageall  (GRT in register tons) Deck ArrangementThe wheelhouse can be situated aft or forward, but on larger vessels the bridge is generally placed aft. In typical arrangements the gear is hauled from the bow or from the side with a mechanical or hydraulic line hauler and the lines are set over the stern. In compliance with emerging regulations many longliners now are arranged so that the shooting station aft incorporates the capacity to set the line from an underwater position underwater to minimize bird strikes.Catch Handling and Processing EquipmentAll.EquipmentDeck EquipmentSmall scale longliners may haul by hand into baskets or tubs or by using a hand cranked line drum. Larger vessels may use automatic or semi-automatic systems to bait the hooks and to shoot and haul the lines. Line storage on larger vessels normally incorporates a line drum as the lines may be as long as 40 miles. There will also be appropriate means of storing and maintaining bait, depending on the type of operation and the bait to be used as well as baiting and shooting apparatus. Equipment to monitor water temperature may also be carried.Fish Detection EquipmentTypical fish detection equipment of long liners includes echosounder. On larger vessels also sonar is usually present on board.Fishing GearMidwater or bottom longlines.
