A fishing trawler is a commercial fishing vessel designed to operate fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing boag that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously trawler fishing boat difference list and multi-rig.

There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful trawler fishing boat difference list trawling boats are. A trawling boat can be a small open boat with only 30 horsepower 22 kW or a large factory ship with 10, horsepower kW.

Trawl variants include beam trawls, large-opening midwater trawls, and large bottom trawls, such as "rock hoppers" that are rigged with heavy rubber wheels that let the net crawl over rocky. During the 17th century, the British developed the Doggeran early type of sailing trawler commonly operated liwt the North Sea.

The Dogger takes its name from the Dutch word doggermeaning a fishing vessel which tows a trawl. The modern fishing trawler was developed in the 19th century, at the English fishing port of Brixham. By the early 19th century, the fishermen at Brixham needed to expand their fishing area further than ever before due to the ongoing depletion of stocks that was occurring in the overfished waters of South Devon.

The Brixham trawler that evolved there was of a sleek build and had a tall gaff rigwhich gave the vessel sufficient speed to make long-distance trips out to the fishing grounds in the ocean.

They were also sufficiently robust to be able to tow large trawls in deep water. The great trawling fleet that built up at Brixham, earned the village trawler fishing boat difference list title of 'Mother of Deep-Sea Fisheries'. This revolutionary design made large scale trawling in the ocean possible for the first time, resulting in a substantial migration of fishermen from trawler fishing boat difference list ports in the South of England, to trawler fishing boat difference list further north, such as ScarboroughHullGrimsbyHarwich and Yarmouththat were points of access to the large fishing grounds in the Atlantic Ocean.

The small village of Grimsby grew to become the 'largest fishing port in the world' [6] by the mid 19th century. With the tremendous Trawler Fishing Boat Difference Questions expansion in the fishing industry, the Grimsby Dock Company was opened trawler fishing boat difference list as the first modern fishing port. The elegant Trawler fishing boat difference list trawler spread across the world, influencing fishing fleets.

These trawlers were sold to fishermen around Europe, including from the Netherlands and Scandinavia. Twelve trawlers went on to form the nucleus of the German fishing fleet. The earliest steam-powered fishing boats first appeared in the s and used the trawl system of fishing as well as lines and drift nets. These were large boats, usually 80�90 feet 24�27 m in length with a beam of differnce 20 feet 6. The dishing purpose-built fishing vessels were designed and made by David Allan in Leith in Marchwhen he converted a drifter to steam power.

Indifcerence built the first screw-propelled steam trawler trawler fishing boat difference list the world. This vessel was Pioneer LH She was of wooden construction with two masts and carried a gaff-rigged main and dkfference using booms, and a single foresail.

Allan argued that his motivation for steam power was to increase the safety of fishermen. However local fishermen Trawler Fishing Boat Difference saw power trawling as a threat.

Allan built a total of ten boats at Leith between and Twenty-one boats were completed at Grantonhis last vessel being Degrave in The first steam boats were made of wood, but steel hulls were soon introduced and were divided into watertight compartments.

They were well designed for the crew with a large building that contained the wheelhouse and the Trawler Fishing Boat Difference Effect deckhouse. The boats built in the 20th century only had a mizzen sailwhich was used to help steady the boat when its nets were. The main function of the mast was trawler fishing boat difference list as a crane for lifting the boah ashore. It also had a steam capstan on the foredeck near the mast for hauling nets.

These boats had a crew of twelve made traw,er of a skipperdriver, fireman to look after the boiler and nine deck hands. Steam fishing boats had many advantages. They were usually about 20 ft longer 6. This was important, as the market was growing quickly at the beginning of the 20th century. They could travel faster and further and with greater freedom from weatherwind and tide.

Because less time was spent travelling to and from the fishing grounds, more time could be spent fishing. The steam boats also gained the highest prices for their fish, as they could return quickly to harbour with their fresh catch. Steam trawlers were introduced at Grimsby and Hull in the s. In it was estimated that there were 20, men on the North Fisuing. The steam drifter was not used in the herring fishery until The last sailing fishing trawler was built in in Grimsby.

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. The first trawlers fished over the side, rather than over the stern. The first purpose-built stern trawler was Fairtry built in at Aberdeen.

The ship was much larger than lizt other trawlers then in operation and inaugurated trawller era of the 'super trawler'. As the ship pulled its nets over the stern, it could lift out a much greater haul of up to 60 tonnes.

Lord Nelson followed ininstalled with vertical plate freezers that had been researched and built at the Ddifference Research Station. These ships served as a basis for the expansion of 'super trawlers' around the world in the following decades. 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 Warsome countries fitted fishing diffference with additional electronic gear so they could be used fisning spy ships to monitor the activities of other countries. Modern trawlers are usually decked vessels designed for robustness. Their superstructure wheelhouse and accommodation can be forward, midship or aft.

Motorised wincheselectronic navigation and sonar systems trawler fishing boat difference list usually installed. Fishing equipment varies in sophistication depending on the size of the vessel and the technology used.

Design features trawler fishing boat difference list modern fishing trawlers vary substantially, as many national maritime jurisdictions do not impose compulsory vessel inspection standards for smaller commercial fishing vessels. Mechanised hauling devices are used on modern trawlers. Trawl winches, such as Gilson winches, net drums [16] and other auxiliary winches are installed on deck to control the towing warps trawling wires and store them when not in use.

Modern trawlers make extensive use of contemporary electronics, including navigation and communication equipment, fish detection devices, and equipment to control and monitor gear. Just which equipment will be installed depends on the size and type of the trawler. Much of this equipment can be controlled from the wheelhouse or bridge. Smaller trawlers have wheelhouses, where electronic equipment for navigation, communications, fish detection and trawl sensors are typically arranged about the skipper's chair.

Larger vessels have a bridge, with fishhing command console at the centre and a further co-pilot chair.

Modern consoles display all the key information on an integrated display. Less frequently used sensors and monitors may be mounted on the deckhead. Navigational instruments, such as an trawler fishing boat difference list and GPS fishingg, are used for manoeuvring the vessel in harbour and at sea.

Radar can be used, for example, when pair trawling to keep the correct distance between the two vessels. Communication instruments range from basic radio devices to maritime distress systems and EPIRBsas well as devices for communicating with the crew. Fish detection devices, such as echosounders and sonarare used to locate fish.

During trawling operations, a range of trawl sensors may be used to assist with controlling and monitoring gear. These are often referred to as "trawl monitoring systems" or "net mensuration systems".

Modern trawlers store the fish they catch in some form of chilled condition. At the least, the fish will be stored in boxes covered with ice or stored with ice in the fish hold. In general, the fish are kept fresh by chilling them with ice or refrigerated sea water, or freezing them in blocks.

Also, many trawlers carry out some measure of onboard fish processingand the larger the vessel, the more likely trawler fishing boat difference list is to include fish processing facilities.

For example, the catch can undergo some preliminary processing by being passed through sorting and washing devices. At a further stage, the fish might be mechanically gutted and filleted. Factory trawlers may process fish oil and fish meal and may include canning plants.

Crew quarters are usually below the wheelhouse and may include bunkswith cot sides to stop the occupant from rolling out in heavy trawler fishing boat difference list. The need for drying sea clothes is shown by a notice in at least one steam trawler's boiler room saying trawler fishing boat difference list Do not dry oil frocks over the boiler ".

Trawlers can be classified by their architecture, the type of fish trawler fishing boat difference list catch, the fishing method used, or geographical origin.

The classification used below follows the FAOwho classify trawlers by the gear they use. Outrigger trawlers use outriggersor booms, to tow the trawl. These outriggers are usually fastened to, or at the foot of the mast and extend out over the sides of the vessel during fishing operations. Each side can deploy a twin trawl or a single otter trawl. Outrigger trawlers may have trawler fishing boat difference list superstructure forward or aft.

Warp winches with capstans are installed on the deck to haul the catch. Outrigger trawlers use vertical fish finders of different kinds, according to their size. Beam trawlers are a type of outrigger trawler abovewith the superstructure aft and the working deck amidships.

They use bot very strong outrigger boom on each side, each towing a beam trawlwith the warps going through blocks at the end of the boom. This arrangement makes it easier to stow and handle the large beams. The outriggers are controlled from a midship A-frame or mast. The towing djfference is forward of the superstructure, with the towing warps passed through deck bollards and then out to the towing blocks on the booms.

Beam trawling is used in the flatfish fisheries in the North Sea.
