‘wind knots‘, that’s the denialists‘ term for casting knots and no, they’re not just made by tailing loops or outrageous casting faults but today’s reminder isn’t about the causes of these knots however embarrassing or annoying they may be but of their consequence.
in other words, these knots kink the mono and greatly reduce the original breaking point of the monofilament material they’re made of.
as we’ll see in Simon Gawesworth’s video, percentages on specific materials vary but generally speaking, that reduction is approximately 50% and that puts us in a very precarious situation if a fish takes our fly because well, we’re left with half the strength threshold we originally counted on.
to make things worse and if i understand correctly, Instron-type machines used to register elongation and breaking strains do so in a steady, smooth, pulling manner but fish tend to not follow the same procedure…
although i can’t prove this with numbers i’m very certain that sudden tugs and bursts of strength means our knotted lines will be even weaker relatively speaking than those 50 or so %.
apart from the denialists, these knots happen to everyone at one point or another and if we want to not get into trouble and leave hooks in fish mouths, there’s only one remedy and that’s to regularly check our leaders and tippets, specially if there’s the slightest doubt or after an obvious yucky cast.
– no knots, carry on as usual.
– find a knot ? is it loose as in the pic ? just undo it and just to be sure, check for kinks.
– did it tighten/seat ? cut it off and rejoin the two pieces.
– if the knot’s too close to the fly or other ‘good’ leader knot, just replace the whole piece and you’ll be able to fish in peace.
