Uses: The San Diego Jam Knot is also known as the Reverse Clinch Knot and as the Heiliger Knot. The San Diego Jam Knot was popularized in San Diego particularly with long-range tuna fisherman. It is reasonably easy to tie at sea and is suitable for monofilament, braided, and fluorocarbon fishing lines.
Number of turns: The number of turns should be decreased with size, ranging from about 7 to 8 turns for 10lb line down to 3 turns for 40lb line.
Tying it: When tightening the San Diego Jam Knot, ensure that the turns form a neat spiral and don’t overlap each other.
Strength: Comparison testing suggests that the San Diego Jam Knot probably retains the strength of the line better than most fishing knots.
Advantages: The San Diego Jam Knot is relatively easy to learn and to tie – even in adverse conditions.
