San Diego jamb knot – staff report
[dropcap]T[/dropcap]he Sand Diego jamb knot is attributed to San Diego’s tuna fishing fleet. It’s by far the strongest terminal knot. Although at first glance it looks similar to the improved clinch knot, it is not, as the illustration below shows (fourth step – black arrow). The San Diego jam uses wraps around both the tag end and standing line, giving the knot a better cushion and is much stronger than clinch knots, which wrap only one strand.The San Diego jamb knot is rated at 147% strength.
Knot Strengths of other commonly used terminal knots; improved clinch knot = 86%; Palomar = 91%, and a Trilene = 87%.
See the red arrow: keep loop open – pinch between thumb and index finger.
See the black arrow: seating this knot requires a lot of “sliding” together so be sure a totally moisten so as not to ‘burn’ the mono.
