History

The San Diego Jam Knot, also known as the Reverse Clinch Knot or Heiliger Knot, was popularized by tuna fishermen in San Diego, California, for tying heavy jigs on long-range fishing trips. Its design, similar to the Clinch Knot but tied in reverse, emerged to meet the demands of securing lines under extreme tension, as noted in fishing communities. While not listed in The Ashley Book of Knots, its widespread use in modern angling highlights its reliability and simplicity for diverse fishing lines.

Security Level

The San Diego Jam Knot is highly reliable, retaining up to 95% of line strength when tied correctly, making it suitable for heavy fish like tuna. For critical applications, use 6-7 wraps and wet the knot to prevent damage during cinching. A stopper knot on the tag end can enhance security, though careful tightening is key to avoid weakening the line.

Downsides

• Cinching care: Requires slow, moistened tightening to avoid line damage.
• Learning curve: Needs practice for neat wraps and smooth cinching.

Structure

1. Pass the tag end of the line through the eye of the hook or lure, pulling about 6-8 inches through.
2. Double the tag end back, running it parallel to the main line toward the eye.
3. Wrap the tag end around both the main line and itself 5-7 times, working toward the eye (use more wraps for light line, fewer for heavy).
4. Pass the tag end through the loop formed near the eye, then through the larger loop created by the wraps.
5. Wet the knot with water or saliva, then pull the main line and tag end slowly to cinch it tightly, trimming excess tag end.

Pro Tip: Wet the line before cinching to prevent friction damage. Ensure wraps are neat and stacked to maximize strength. Pull steadily when tightening to avoid line burn or weak spots.

Important Notes on Safety

Common failure points include line burn from dry cinching or uneven wraps. Always verify wraps are stacked neatly and the knot is snug before fishing. Inspect the line for wear or nicks before tying. Wet the knot during cinching to prevent friction damage.
