Deck TypeDecked vesselsOverviewTrollers range from small open boats and canoes up to large refrigerated vessels of 25 or 30 meters length. These vessels may work day trips or month long voyages. Normally the vessels are powered by engines but the use of sails is also common in trolling operations as the vessel is making way when fishing. In many tropical areas, trolling is conducted by sailing canoes, usually having outriggers for stability. Using a properly designed vessel, trolling can be an economical and efficient way of catching tunas, mackerel and other pelagic fish swimming close to the surface.Vessel ClassLength<30 meters  (LOA) PowerallTonnageall  (GRT in register tons) Deck ArrangementAccording to area of operation, vessels laid out with wheelhouse and mast in most cases forward.Catch Handling and Processing EquipmentAll.EquipmentDeck EquipmentUndecked canoes may have no equipment or only a hand cranked reel. Purpose built trollers are usually equipped with two or four trolling booms which are raised and lowered by topping lifts and held in fishing position by adjustable stays. Hydraulic or electrically powered reels (gurdies) are frequently used to haul in the lines.Fish Detection EquipmentNo specific fish detection equipment is required for trolling. Visual scouting to detect fish aggregation areas such as floating weed lines is a very common practice.Fishing Gear Trolling lines.
