Fishing Trawler
A fishing trawler is a commercial fishing vessel designed to operate Trawling, 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 nets 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 (double-rig and multi-rig). There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful the trawling boats are. A trawling boat can be a small open boat with only 30 horsepower (22 kW) or a large factory ship with 10,000 horsepower (7457 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 bottom.

Naval Trawler
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some—known in the Royal Navy as "Admiralty trawlers"— were purpose-built to naval specifications, others adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a or gun in the bow equipped the trawler for anti-submarine duties. History Armed trawlers were also used to defend fishing groups from enemy aircraft or submarines. The smallest civilian trawlers were converted to danlayers. Contemporary Some nations still use armed trawlers for fisheries protection and patrol. The Indian Navy used naval trawlers for ...

Trawlers Of The Royal Navy
Naval trawlers were purpose-built or requisitioned and operated by the Royal Navy (RN), mainly during World Wars I and II. Vessels built to Admiralty specifications for RN use were known as Admiralty trawlers. All trawlers operated by the RN, regardless of origin, were typically given the prefix HMT, for "His Majesty's Trawler". Summary First World War The trawler Viola, built in 1906 at Hull and requisitioned September 1914 is the oldest surviving steam trawler in the world. She is currently beached at Grytviken in South Georgia, though there are currently plans to return her to Hull. Second World War Requisitioned trawlers There were also 215 trawlers of no specific class These were commercial trawlers that the Admiralty requisitioned. The Royal Navy classified requisitioned trawlers by manufacturer, although such classes were more diverse than traditional naval classifications. Seventy-two requisitioned trawlers were lost.

Recreational Trawler
Recreational trawlers are pleasure boats that resemble fishing trawlers. They are also be called cruising trawlers or trawler yachts. Within the category, however, are many types and styles of vessels. A fishing trawler for example, always has a displacement hull for load-carrying capacity. Recreational trawlers, on the other hand, are as likely to have a semi-displacement hull. However, with the rising cost of fuel and the lower fuel consumption (though also lower speed) offered by displacement hulls, they are gaining popularity among some buyers. These displacement models typically have a cruising speed of depending on the boat length. Their maximum speed is often no more than , whereas semi-displacement hulls can attain . Recreational trawlers need only a small engine; can be adequate in a boat, which will use less than to cruise.Buehler, George (2011''The troller yacht book: How to cross oceans without getting wet or going broke''2nd edition, BookLocker.com. .
