San Diego Jam (Reverse Clinch) Knot Details
Uses: The San Diego Jam Knot is also known as the Reverse Clinch Knot and as the Heiliger Knot. It 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 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 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 knots.
Advantages: It is relatively easy to learn and to tie – even in adverse conditions.
