Once tripped they offer much less resistance when reeling in a fish. Inlines are popular with walleye fishermen. Inline boards are attached directly to the fishing line and a spring tension clip that releases upon setting or tripping the planer board so it slides down the fishing line to a swivel tied several feet in front of the lure. Dual board designs consist of two boards that are spaced apart and attached by a line to a mast near the front of the boat with a separate fishing line in a spring tension release clip that separates when the fishing line is set. ![]() They come in dual board and inline board designs. "Planer boards" are trolled devices designed to spread fishing lures out away from the fishing vessel. There are many inventive spreader designs, such as devices which cause the baited hooks or lures to move in helical patterns, in a sophisticated emulation of the schooling behaviour of a group of fish. "Spreaders" allow multiple baited hooks or lures to be trolled from a single line. The devices can place the lure or bait at designated depths and positions and in this way multiple devices can be towed at the same time without the devices and bait interfering with each other. These kites have various shapes, such as arrowhead paravanes, flexi-wing paravanes, and bi-wing paravanes. "Paravanes" (underwater kites) are sometimes used as depth controlling devices, particularly in commercial tuna fishing operations. For example, man-made reservoirs can contain submerged trees and other structures beneath the surface which downriggers can snag. The fishing line is reeled in by a spool powered either by manual cranking or by an electric motor. A clip called a "line release" attaches the fishing line to the weight, and the bait or lure is attached to the release. A downrigger consists of a one or two metre horizontal pole which supports a weight, typically about three kilograms of lead, on a steel cable. In practice, fish swim at different depths according to factors such as the temperature and amount of light in the water, and the speed and direction of water currents. Downrigger ĭownrigger are devices used while trolling to keep a bait or lure at the desired depth. ![]() A boat which trolls enough lines can simulate a school of fish. Outriggers are poles which allow a boat to troll several lines in the water without tangling. Downriggers can also be used to keep the lures or baits trailing at a desired depth.īy Currier & Ives, 1866 Outriggers Multiple lines are often used, and outriggers can be used to spread the lines more widely and reduce their chances of tangling. This can be accomplished with the use of a special trolling motor. Trolling from a moving boat involves moving quite slowly through the water. Trolling is used both for recreational and commercial fishing whereas trawling is used mainly for commercial fishing. In American English, trolling can be phonetically confused with trawling, a different method of fishing where a net (trawl) is drawn through the water instead of lines. Trolling is used to catch pelagic fish such as salmon, mackerel and kingfish. This may be behind a moving boat, or by slowly winding the line in when fishing from a static position, or even sweeping the line from side-to-side, e.g. Trolling is a method of fishing where one or more fishing lines, baited with lures or bait fish, are drawn through the water.
