A fishing vessel is a boat or ship used to catch fish in the sea, or on a lake or river. Many different kinds of vessels are used in commercial, artisanal and recreational fishing.

According to the FAO, there are currently (2004) four million commercial fishing vessels.[1] About 1.3 million of these are decked vessels with enclosed areas. Nearly all of these decked vessels are mechanised, and 40,000 of them are over 100 tons. At the other extreme, two-thirds (1.8 million) of the undecked boats are traditional craft of various types, powered only by sail and oars.[1] These boats are used by artisan fishers.

It is difficult to estimate the number of recreational fishing boats. They range in size from small dingies to large charter cruisers, and unlike commercial fishing vessels, are often not dedicated just to fishing.

Prior to the 1950s there was little standardisation of fishing boats. Designs could vary between ports and boatyards. Traditionally boats were built out of wood, but wood is not often used now because of cost and the difficulty in obtaining suitable timber. Fibreglass is used increasingly in smaller fishing vessels up to 25 metres (100 tons), while steel is usually used on vessels above 25 metres.

History

Dugouts on the shore of Lake Malawi

Early fishing vessels included rafts, dugout canoes, and boats constructed from a frame covered with hide or tree bark, along the lines of a coracle.[2] The oldest boats found by archaeological excavation are dugout canoes dating back to the Neolithic Period around 7,000-9,000 years ago. These canoes were often cut from coniferous tree logs, using simple stone tools.[3][2] A 7000 year-old sea going boat made from reeds and tar has been found in Kuwait.[4] These early vessels had limited capability; they could float and move on water, but were not suitable for use any great distance from the shoreline. They were used mainly for fishing and hunting.

The development of fishing boats took place in parallel with the development of boats built for trade and war. Early navigators began to use animal skins or woven fabrics for sails. Affixed to a pole set upright in the boat, these sails gave early boats more range, allowing voyages of exploration

Around 4000 B.C., Egyptians were building long narrow boats powered by many oarsmen. Over the next 1,000 years, they made a series of remarkable advances in boat design. They developed cotton-made sails to help their boats go faster with less work. Then they built boats large enough to cross the oceans. These boats had sails and oarsmen, and were used for travel and trade. By 3000 BC, the Egyptians knew how to assemble planks of wood into a ship hull.[5] They used woven straps to lash planks together,[5] and reeds or grass stuffed between the planks to seal the seams.[5] An example of their skill is the Khufu ship, a vessel 143 feet (44 m) in length entombed at the foot of the Great Pyramid of Giza around 2,500 BC and found intact in 1954.

At about the same time, the Scandinavians were also building innovative boats. People living near Kongens Lyngby in Denmark, came up with the idea of segregated hull compartments, which allowed the size of boats to gradually be increased. A crew of some two dozen paddled the wooden Hjortspring boat across the Baltic Sea long before the rise of the Roman Empire. Scandinavians continued to develop better ships, incorporating iron and other metal into the design and developing oars for propulsion.

The oldest Nordic shipfind is the Nydam boat, found preserved in the Nydam Mose bog in Sundeved, Denmark. It has been dendro dated to 310-320 AD., and is the oldest known boat to use clinker planking, where the planks overlap one another. Built of oak, it is 23 metres long and about 4 metres wide. It originally weighed over three tonnes and was rowed by thirty men.

By 1000 A.D. the Norsemen were pre-eminent on the oceans. They were skilled seamen and boat builders, with clinker-built boat designs that varied according to the type of boat. Trading boats, such as the knarrs, were wide to allow large cargo storage. Raiding boats, such as the longship, were long and narrow and very fast. The vessels they used for fishing were scaled down versions of their cargo boats. The Scandinavian innovations influenced fishing boat design long after the Viking period came to an end. For example, yoles from the Orkney island of Stroma were built in the same way as the Norse boats.

Herring Buss taking aboard its drift net (G. Groenewegen)

In the 15th century, the Dutch developed a type of sea-going herring drifter that became a blueprint for European fishing boats. This was the Herring Buss, used by Dutch herring fishermen until the early 19th centuries. The ship type buss has a long history. It was known around 1000 AD in Scandinavia as as a bǘza, a robust variant of the Viking longship. The first herring buss was probably built in Hoorn around 1415. The last one was built in Vlaardingen in 1841. The ship was about 20 meters long and displaced between 60 and 100 tons. It was a massive round-bilged keel ship with a bluff bow and stern, the latter relatively high, and with a gallery. The busses used long drifting gill nets to catch the herring. The nets would be retrieved at night and the crews of eighteen to thirty men[6] would set to gibbing, salting and barrelling the catch on the broad deck. The ships sailed in fleets of 400 to 500 ships[6] to the Dogger Bank fishing grounds and the Shetland isles. They were usually escorted by naval vessels, because the English considered they were "poaching". The fleet would stay at sea for weeks at a time. The catch would sometimes be transferred to special ships (called ventjagers), and taken home while the fleet would still be at sea (the picture shows a ventjager in the distance).[6]

During the 17th century, the British developed the dogger, an early type of sailing trawler or longliner, which commonly operated in the North Sea. The dogger takes its name from the Dutch word dogger, meaning a fishing vessel which tows a trawl. Dutch trawling boats were common in the North Sea, and the word dogger was given to the area where they often fished, which became known as the Dogger Bank.[7] Doggers were slow but sturdy, capable of fishing in the rough conditions of the North Sea.[8] Like the herring buss, they were wide-beamed and bluff-bowed, but considerably smaller, about 15 meters long, a maximum beam of 4.5 meters, a draught of 1.5 meters, and displacing about 13 tonnes. They could carry a tonne of bait, three tonnes of salt, half a tonne each of food and firewood for the crew, and return with six tonnes of fish.[8] Decked areas forward and aft probably provided accommodation, storage and a cooking area. An anchor would have allowed extended periods fishing in the same spot, in waters up to 18 meters deep. The dogger would also have carried a small open boat for maintaining lines and rowing ashore.[8]

Typically schooners were used as dory mother ships

Dories are small, shallow-draft boats, usually about five to seven metres (15 to 22 feet) long. They are lightweight versatile boats with high sides, a flat bottom and sharp bows, and are easy to build because of their simple lines. The dory first appeared in New England fishing towns sometime after the early 1700s.[9] A precursor to the dory type was the early French bateau type, a flat bottom boat with straight sides used as early as 1671 on the Saint Lawrence River.[10]. The common coastal boat of the time was the wherry and the merging of the wherry design with the simplified flat bottom of the bateau resulted in the birth of the dory. Antecdotal evidence exists of much older precursors throughout Europe. England, France, Italy, and Belgium have small boats from medieval periods that could reasonably be construed as predecessors of the Dory. [11]

The Banks dories appeared in the 1830s. They were designed to be carried on mother ships and used for fishing cod at the Grand Banks.[9]. Adapted almost directly from the low freeboard, french river bateaus, with their straight sides and removable thwarts, bank dories could be nested inside each other and stored on the decks of fishing schooners, such as the Gazela Primeiro, for their trip to the Grand Banks fishing grounds.

In the 19th century, a more effective design for sailing trawlers was developed at the English fishing port, Brixham. These elegant wooden sailing boats spread across the world, influencing fishing fleets everywhere. Their distinctive sails inspired the song Red Sails in the Sunset, written aboard a Brixham sailing trawler called the Torbay Lass. In the 1890s there were about 300 trawling vessels there, each usually owned by the skipper of the boat. Several of these old sailing trawlers have been preserved.[12][13]

Throughout history, local conditions have led to the development of a wide range of types of fishing boats. The Lancashire nobby was used down the north west coast of England as a shrimp trawler from 1840 until World War II. The Manx nobby was used around the Isle of Man as a herring drifter. The fifie was also used as a herring drifter along the east coast of Scotland from the 1850s until well into the 20th century.

Steam seine netter

The bawley and the smack were used in the Thames Estuary and off East Anglia, while trawlers and drifters were use on the east coast. Herring fishing started in the Moray Firth in 1819. The peak of the fishing at Aberdeen was in 1937 with 277 steam trawlers, though the first diesel drifter was introduced in 1926. In 1870 paddle tugs were being used to tow luggers and smacks to sea. Steam trawlers were introduced in 1881, mainly at Grimsby and Hull. In 1890 it was estimated that there were 20,000 men on the North Sea. The steam drifter was not used in the herring fishery until 1897. The first trawlers fished over the side but in 1961 the first stern trawler was used at Lowestoft for fishing in Arctic waters. By 1981 only 27 of 130 deep sea trawlers were still going to sea. Many were converted to oil rig safety vessels.

Trawler designs adapted as the way they were powered changed from sail to coal-fired steam by World War I to diesel and turbines by the end of World War II. During World War I and World War II, many fishing trawlers were commissioned as naval trawlers to be used as minesweepers, the activities being similar, with the crew and layout already suited to the task. Likewise, many commercial drifters were commissioned as naval drifters to be used for maintaining and monitoring anti-submarine nets. Since World War II, commercial fishing vessels have been increasingly equipped with electronic aids, such as radio navigation aids and fish finders. During the Cold War, some countries fitted fishing trawlers with additional electronic gear so they could be used as spy ships to monitor the activities of other countries.

Commercial vessels

The German factory ship Kiel NC 105

The 200-mile fishing limit has changed fishing patterns and, in recent times, fishing boats are becoming more specialised and standardised. In the United States and Canada more use is made of large factory trawlers, while the huge blue water fleets operated by Japan and the Soviet-bloc countries have contracted. In western Europe, fishing vessel design is focused on compact boats with high catching power.

Commercial fishing is a high risk industry, and countries are introducing regulations governing the construction and operation of fishing vessels. The International Maritime Organization, convened in 1959 by the United Nations, is responsible for devising measures aimed at the prevention of accidents, including standards for ship design, construction, equipment, operation and manning.

According to the FAO, in 2004 the world's fishing fleet consisted of 4 million vessels. Of these, 1.3 million were decked vessels with enclosed areas. The rest were open vessels, of which two-thirds were traditional craft propelled by sails and oars. [1] By contrast, nearly all decked vessels were mechanized. Of the decked vessels, 86 percent are found in Asia, 7.8 percent in Europe, 3.8 percent in North and Central America, 1.3 percent inAfrica, 0.6 percent in South America and 0.4 percent in Oceania.[1] Most commercial fishing boats are small, usually less than than 30 metres (98 ft) but up to 100 metres (330 ft) for a large purse seiner or factory ship.

Commercial fishing vessels can be classified by architecture, the type of fish they catch, the fishing method used, or geographical origin. The following classification follows the FAO,[14] who classify commercial fishing vessels by the gear they use.

Fishing gear

Trawlers

File:Drawing of a trawler.gif
File:Drawing of a large trawler.gif

A trawler is a fishing vessel designed to use trawl nets in order to catch large volumes of fish.[15]

  • Outrigger trawlers - use outriggers to tow the trawl. These are commonly used to catch shrimp. One or two otter trawls can be towed from each side. Beam trawlers, employed in the North sea for catching flatfish, are another form of outrigger trawler. Medium sized and high powered vessels, these tow a beam trawl on each side at speeds up to 8 knots.[16] Drawing (FAO)
  • Beam trawlers - use sturdy outrigger booms for towing a beam trawl, one warp on each side. Double-rig beam trawlers can tow a separate trawl on each side. Beam trawling is used in the flatfish and shrimp fisheries in the North Sea. They are medium sized and high powered vessels, towing gear at speeds up to 8 knots. To avoid the boat capsizing if the trawl snags on the sea floor, winch brakes can be installed, along with safety release systems in the boom stays. The engine power of bottom trawlers is also restricted to 2000 HP (1472 KW) for further safety.[17] Drawing (FAO)
  • Otter trawlers - deploy one or more parallel trawls kept apart horizontally using otter boards. These trawls can be towed in midwater or along the bottom. [18]
  • Pair trawlers - are trawlers which operate together towing a single trawl. They keep the trawl open horizontally by keeping their distance when towing. Otter boards are not used. Pair trawlers operate both midwater and bottom trawls.[19]
  • Side trawlers - have the trawl set over the side with the trawl warps passing through blocks which hang from two gallows, one forward and one aft. Until the late sixties, side trawlers were the most familiar vessel in the North Atlantic deep sea fisheries. They evolved over a longer period than other trawler types, but are now being replaced by stern trawlers.[20] Drawing (FAO)
  • Stern trawlers - have trawls which are deployed and retrieved from the stern. Larger stern trawlers often have a ramp, though pelagic and small stern trawlers are often designed without a ramp. Stern trawlers are designed to operate in most weather conditions. They can work alone when midwater or bottom trawling, or two can work together as as pair trawlers.[21] Drawing (FAO)
  • Freezer trawlers - The majority of trawlers operating on high sea waters are freezer trawlers. They have facilities for preserving fish by freezing. They are medium to large size trawlers, with the same general arrangement as stern or side trawlers.[22] Drawing (FAO)
  • Wet fish trawlers - are trawlers where the fish is kept in the hold in a fresh/wet condition. They must operate in areas not far distant from their landing place, and the fishing time of such vessels is limited.[23] Drawing (FAO)

Seiners

Seiners use surrounding and seine nets. This is a large group ranging from open boats as small as 10 metres in length, to ocean going vessels. There are also specialised gears that can target demersal species.[24][25]

  • Purse seiners - are very effective at targeting aggregating pelagic species near the surface. The seiner circles the shoal with a deep curtain of netting, possibly using bow thrusters for better manoeuvrability. Then the bottom of the net is pursed (closed) underneath the fish shoal by hauling a wire running from the vessel through rings along the bottom of the net and then back to the vessel. The most important part of the fishing operation is searching for the fish shoals and assessing their size and direction of movement. Sophisticated electronics, such as echosounders, sonar, and track plotters, may be used are used to search for and track schools; assessing their size and movement and keeping in touch with the school while it is surrounded with the seine net. Crows nests may be built on the masts for further visual support. Large vessels can have observation towers and helicopter landing decks. Helicopters and spotter planes are used for detecting fish schools. The main types of purse seiners sre the the American seiners, the European seiners and the Drum seiners.[26]
  • American seiners - have their bridge and accommodation placed forward with the working deck aft. American seiners are most common on both coasts of North America and in other areas of Oceania. The net is stowed at the stern and is set over the stern. The power block is usually attached to a boom from a mast located behind the superstructure. American seiners use triplerollers A purse line winch is located amidships near the hauling station, near the side where the rings are taken onboard.[25]Drawing (FAO)
  • European seiners - have their bridge and accommodation located more to the after part of the vessel with the working deck amidships. European seiners are most common in waters fished by European nations The net is stowed in a net bin at the stern, and is set over the stern from this position. The pursing winch is normally positioned at the forward part of the working deck.[27]Drawing (FAO)
  • Drum seiners - have the same layout as American seiners except a drum is mounted on the stern and used instead of the power block. They are mainly used in Canada and USA.[28]Drawing (FAO)
  • Tuna purse seiners - are large purse seiners, normally over 45 meters, equipped to handle large and heavy purse seines for tuna. They have the same general arrangement as the American seiner, with the bridge and accommodation placed forward. A crows nest or tuna tower is positioned at the top of the mast, outfitted with the control and manoeuvre devices. A very heavy boom which carries the power block is fitted at the mast. They often carry a helicopter to search for tuna schools. On the deck are three drum purse seine winches and a power block, with other specific winches to handle the heavy boom and net. They are usually equipped with a skiff.[29]Drawing (FAO)
  • Seine netters - the basic types of seine netters are the Anchor seiners and Scottish seiner in northern Europe and the Asian seiners in Asia.[30]Drawing (FAO)
  • Anchor seiners - have the wheelhouse and accommodation aft and the working deck amidships, thus resembling side trawlers. The seine net is stored and shot from the stern, and they may carry a power block. Anchor seiners have the coiler and winch mounted transversally amidships.[30]
  • Scottish seiners - are basically configured the same as anchor seiners. The only difference is that, whereas the anchor seiner has the coiler and winch mounted transversally amidships, the Scottish seiner has them mounted transversally in the forward part of the vessel.[30]
  • Asian seiners - In Asia the seine netter usually has the wheelhouse forward and the working deck aft, in the manner of a stern trawler. However, in regions where the fishing effort is a labour intensive, low technology approach, they are often undecked and may be powered by outboards motors, or even by sail.[30]

Line vessels

Line vessels -

  • Longliners - use one or more long heavy fishing lines with a series of hundreds or even thousands of baited hooks hanging from the main line by means of branch lines called "snoods". Hand operated longlining can be operated from boats of any size. The number of hooks and lines handled depends on the size of vessel, the number of crew, and the level of mechanisation. Large purpose built longliners can be designed for single species fisheries such as tuna. On such larger vessels the bridge is usually placed aft, and the gear is hauled from the bow or from the side with mechanical or hydraulic line haulers. The lines are set over the stern. Automatic or semi-automatic systems are used to bait hooks and shoot and haul lines. These systems include rail rollers, line haulers, hook separators, dehookers and hook cleaners, and storage racks or drums. To avoid incidental catches of seabirds, and outboard setting funnel is used to guide the line from the setting position on the stern down to a depth of one or two metres. Small scale longliners handle the gear by hand. The line is stored into baskets or tubs, perhaps using a hand cranked line drum.[31]Drawing (FAO)
  • Bottom longliners - [32]
  • Midwater longliners - are usually medium sized vessels which operate worldwide, purpose built to catch large pelagics. The line hauler is usually forward starboard, where the fish are hauled through a gate in the rail. The lines are set from the stern where a baiting table and chute are located. These boats need adequate speed to reach distant fishing grounds, enough endurance for continued fishing, adequate freezing storage, suitable mechanisms for shooting and hauling longlines quickly, and proper storage for fishing gears and accessories.[33]
  • Freezer longliners - are outfitted with freezing equipment. The holds are insulated and refrigerated. Freezer longliners are medium to large with the same general characteristics of other longliners. Most longliners operating on the high seas are freezer longliners.[34]
  • Factory longliners - are generally equipped with processing plant, including mechanical gutting and filleting equipment accompanied by freezing facilities, as well as fish oil, fish meal and sometimes canning plants. These vessels have a large buffer capacity. Thus, caught fish can be stored in refrigerated sea water tanks and piks in the catch can also be used. Freezer longliners are large ships, working the high seas with the same general characteristics of other large longliners.[35]
  • Wet-fish longliners - keep the caught fish in the hold in the fresh/wet condition. The fish is stored in boxes and covered with ice, or stored with ice in the fish hold. The fishing time of such vessels is limited, so they operate close to the landing place.[36]
  • Pole and line vessels - are used mainly to catch tuna and skipjack. The fishers stand at the railing or on special platforms and fish with poles and lines. The lines have hooks which are baited, preferably with live bait. Caught tuna are swung on board, by two to three fishermen if the tuna is big, or with an automated swinging mechanism. The tuna usually release themselves from the barbless hook when they hit the deck. Tanks with live bait are places round the decks, and water spray systems are used to attract the fish. The vessels are 15 to 45 metres o/a. On smaller vessels fishers fish from the main deck right around the boat. With larger vessels, there are two different deck styles: the American style and the Japanese style.[37]
  • American style - fishers stand on platforms arranged over the side abaft amidships and around the stern. The vessel moves ahead during fishing operation.[37]Drawing (FAO)
  • Japanese style - fishers stand at the rail in the forepart of the vessel. The vessel drifts during fishing operations.[37]Drawing (FAO)
File:Drawing of a troll vessel.gif
  • Trollers - catch fish by towing astern one of more trolling lines. A trolling line is a fishing line with natural or artificial baited hooks trailed by a vessel near the surface or at a certain depth. Several lines can be towed at the same time using outriggers to keep the lines apart. The lines can be hauled in manually or by small winches. A length of rubber is often included in each line as a shock absorber. The trolling line is towed at a speed depending on the target species, from 2.3 knots up to at least 7 knots. Trollers range from small open boats to large refrigerated vessels 30 meters long. In many tropical artisanal fisheries, trolling is done with sailing canoes with outriggers for stability. With properly designed vessels, trolling is an economical and efficient way of catching tuna, mackerel and other pelagic fish swimming close to the surface. Purpose built trollers are usually equipped with two or four trolling booms raised and lowered by topping lifts, held in position by adjustable stays. Electrically powered or hydraulic reels can be used to haul in the lines.[38]Drawing (FAO)
  • Jiggers - there are two types of jiggers: specialised squid jiggers which work mostly in the southern hemisphere and smaller vessels using jigging techniques in the northern hemisphere mainly for catching cod.[39]
  • Squid jiggers - have single or double drum jigger winches lined along the rails around the vessel. Strong lamps, up to 5000 W each, are used to attract the squid. These are arranged 50–60 centimetres apart, either as one row in the centre of the vessel, or two rows on each side. As the squid are caught they are transferred by chutes to the processing plant of the vessel. The jigging motion can be produced mechanically by the shape of the drum or electronically by adjustment to the winch motor. Squid jiggers are often used during the day as midwater trawlers and during the night as jiggers.[39]
  • Cod jiggers - use single jigger machines and do not use lights to attract the fish. The fish are attracted by the jigging motion and artificial bait.[39]

Other vessels

  • Dredgers - use a dredge for collecting molluscs from the seafloor. There are three types of dredges: (a) The dredge can be dragged along the seabed, scooping the shellfish from the ground. These dredges are towed in a manner similar to beam trawlers, and large dredgers can work three or more dredges on each side. (b) Heavy mechanical dredging units are operated by special gallows from the bow of the vessel. (c) The dredger employs a hydraulic dredge which uses a powerful water pump to operates water jets which flush the molluscs from the bottom. Dredgers don't have a typical deck arrangement, the bridge and accommodation can be aft or forward. Derricks and winches may be installed for lowering and lifting the dredge. Echosounders are used for determining depths.[40]Drawing (FAO)

  • Gillnetters - On inland waters and inshore, gillnets can be operated from open boats and canoes. In coastal waters, they are operated by small decked vessels which can have their wheelhouse either aft or forward. In coastal waters, gillnetting is often used as a second fishing method by trawlers or beam trawlers, depending on fishing seasons and targeted species. For offshore fishing, or fishing on the high seas, medium sized vessels using drifting gillnets are called drifters, and the bridge is usually located aft. The nets are set and hauled by hand on small open boats. Larger boats use hydraulic or occasionally mechanical net haulers, or net drums. These vessels can be equipped with an echosounder, although locating fish is more a matter of the fishermen's personal knowledge of the fishing grounds rather than depending on special detection equipment.[41]Drawing (FAO)
  • Set netters - also operate gillnets. However, during fishing operations the vessel is not attached to the nets. The size of the vessels varies from open boats to large specialised drifters operating on the high seas. The wheelhouse is usually located aft, and the front deck is used for handling gear. Normally the nets are set at the stern by steaming ahead. Hauling is done over the side at the forepart of the deck, usually using hydraulic driven net haulers. Wet fish is packed in containers chilled with ice. Larger vessels might freeze the catch.[42]
  • Lift netters - are equipped to operate lift nets, which are held from the vessel's side and raised and lowered by means of outriggers. Lift netters range from open boats about 10 meters long to larger vessels with open ocean capability. Decked vessels usually have the bridge amidships. Larger vessels are often equipped with winches and derricks for handling the lifting lines, as well as outriggers and light booms. They can be fitted with powerful lights to attract and aggregate the fish to the surface. Open boats are usually unmechanized or use hand operated winches. Electronic equipment, such as fish finders, sonar and echo sounders are used extensively on larger boats.[43]Drawing (FAO)

  • Trap setters - are used to set pots or traps for catching fish, crabs, lobsters, crayfish and other similar species. Trap setters range in size from open boats operating inshore to larger decked vessels, 20 to 50 metres long, operating out to the edge of the continental shelf. Small decked trap setters have the wheelhouse either forward or aft with the fish hold amidships. They use hydraulic or mechanical pot haulers. Larger vessels have the wheelhouse forward, and are equipped with derricks, davits or cranes for hauling pots aboard. Locating fish is often more a matter of the fishermen's knowledge of the fishing grounds rather than the use of special detection equipment. Decked vessels are usually equipped with an echosounder, and large vessels may also have a Loran or GPS.[44]
  • Handliners - are normally undecked vessels used for handlining (fishing with a line and hook}. Handliners include canoes and other small or medium sized vessels. Traditional handliners are less than 12 metres o/a, and do not have special gear handling, there is no winch or gurdy. Locating fish is left to the fishermen's personal knowledge of fishing grounds rather than the use of special electronic equipment. Non traditional handliners can set and haul using electrical or hydraulic powered reels. These mechanised reels are normally fastened to the gunwale or set on stanchions close to or overhanging the gunwale. They operate all over the world, some in shallow waters, some fishing up to 300 meters deep. No typical deck arrangement exists for handliners.[45]
  • Multipurpose vessels - are vessels which are designed so they can deploy more than one type of fishing gear without major modifications to the vessels. The fish detection equipment present on board also changes according to which fishing gear is being used.[46]
  • Trawler/Purse seiners - are designed so the deck arrangement and equipment, including a suitable combination winch, can be used for both methods. Rollers, blocks, trawl gallows and purse davits need to be arranged so they control the lead of warps and pursing lines in such a way as to reduce the time needed to convert from one type to the other. Typical fish detection equipment includes a sonar and an echosounder. These vessels are usually designed as trawlers, since the power requirement for trawling is higher.[47]

  • Research vessels - a fisheries research vessel (FRV) requires platforms which are capable of towing different types of fishing nets, collecting plankton or water samples from a range of depths, and carrying acoustic fish-finding equipment. Fisheries research vessels are often designed and built along the same lines as a large fishing vessel, but with space given over to laboratories and equipment storage, as opposed to storage of the catch. An example of a fisheries research vessel is FRV Scotia.

Artisan vessels

Artisan fishing is a term used to describe small scale commercial or subsistence fishing practises. The term particularly applies to coastal or island ethnic groups using traditional fishing techniques and traditional boats. The term can also be applied to heritage groups involved in customary fishing practices.

According to the FAO, at the end of 2004, the world fishing fleet consisted of about 4 million vessels, of which 2.7 million were undecked (open) boats. While nearly all decked vessels were mechanized, only one-third of the undecked fishing boats were powered, usually with outboard engines. The remaining 1.8 million boats were traditional craft of various types, operated by sail and oars.[1]

These figures for small fishing vessels are probably under reported. The FAO compiles these figures largely from national registers. These records often omit smaller boats where registration is not required or where fishing licences are granted by provincial or municipal authorities.[1]

Artisan fishing boats are usually small traditional fishing boats, appropriately designed for use on their local inland waters or coasts. Many localities around the world have developed their own traditional types of fishing boats, adapted to the specific fisheries and sea conditions in their area. Artisan boats are often open (undecked). Many have sails, but they do not usually use much, or any mechanised or electronic gear. Large numbers of artisan fishing boats are still in use, particularly in developing countries with long productive marine coastlines. For example, Indonesia has reported about 700,000 fishing boats, 25 percent of which are dugout canoes, and half of which are without motors.[48] The Philippines have reported a similar number of small fishing boats. Many of the boats in this area are double-outrigger craft, consisting of a narrow main hull with two attached outriggers, commonly known as jukung in Indonesia and banca in the Philippines.[49]

Recreational vessels

Recreational fishing is done for pleasure or sport, and not for profit or survival. Just about anything that will stay afloat can be called a recreational fishing boat, so long as a fisher periodically climbs aboard with the intent to catch a fish. Usually some form of fishing tackle is brought onboard, such as hooks, lines, sinkers or nets. Fish are caught for recreational purposes from boats which range from dugout canoes, kayaks, rafts, pontoon boats and small dingies to runabouts, cabin cruisers and cruising yachts to large, hi-tech and luxurious big game rigs.[50] Larger boats, purpose-built with recreational fishing in mind, usually have large, open cockpits at the stern, designed for convenient fishing.

Big game fishing started as a sport after the invention of the motorized boat. Charles Frederick Holder, a marine biologist and early conservationist, is credited with founding the sport in 1898.[51] Purpose built game fishing boats appeared shortly after. An example is the Crete, in use at Cataline Island, California, in 1915, and shipped to Hawaii the following year. According to a newspaper report at that time, the Crete had "... a deep cockpit, a chair fitted for landing big fish and leather pockets for placing the pole."[52]

It is difficult to estimate how many recreational fishing boats there are, although the number is high. The term is fluid, since most recreational boats are also used for fishing from time to time. Unlike most commercial fishing vessels, recreational fishing boats are often not dedicated just to fishing.

  • Fishing kayaks have gained popularity in recent years. The kayak has long been a means of accessing fishing grounds.
  • Pontoon boats have also become popular in recent years. These boats allow one or two fishermen to get into small rivers or lakes that would have difficulty accommodating larger boats. Typically 8-12 ft in length, these inflatable craft can be assembled quickly and easily. Some feature rigid frames derived from the white water rafting industry.
  • Bass boats are small aluminium or fibreglass boats used in lakes and rivers in the U.S. for fishing bass and other panfish. They have swivel chairs for the anglers, storage bins for fishing tackle, and a tank with recirculating water for caught fish. They are usually fitted with an outboard motor and a trolling motor.
  • Charter boats are often privately operated, purpose-built fishing boats, and host fishing trips for paying clients. Their size can range widely depending on the type of trips run and the geographical location.
  • Freshwater fishing boats account for approximately one third of all registered boats in the USA. Most other types of boats end up being used for fishing on occasion.
  • Saltwater fishing boats vary widely in size and can be specialized for certain species of fish. Flounder boats, for example, have flat bottoms for a shallow draft and are used in protected, shallow waters. Sport fishing boats range from 25 to 80 feet or more, and can be powered by large outboard engines or inboard diesels. Boats used for fishing in cold climates may have space dedicated to a cuddy cabin or enclosed wheelhouse, while boats in warmer climates are more likely to be open.
