* 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.
* 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
* 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.

* 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.
* 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
* 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.
* 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.

* 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.
