Twisted line is a frustration every angler must deal with at some point. Maybe it happened when adding new line to a spinning reel. Perhaps the twist is due to hooking a large fish and an angler reeling against the drag. Maybe it is caused by reeling or trolling a lure that is spinning in the water. Or sometimes it just happens for inexplicable reasons.
Two potential solutions: (1) before you go fishing, especially if you haven’t been in a while, remove the line spools from your spinning reels and allow them to soak in hot water for 20 or 30 minutes. Monofilament does actually absorb some water and soaking them helps the line lose its “memory.”
(2) If twist occurs while you are on the water, remove any lures or terminal gear from the line. Then idle your boat along at a slow speed, letting your line trail off behind the boat for at least 80 or 100 feet. Allowing the line to trail along in the water under tension causes it to literally untwist. Allow it trail behind the boat two to five minutes, depending upon how bad the twist was. Then it’s back to fishing.
