About the San Diego Jam Knot

The San Diego Jam Knot was developed by West Coast tuna and yellowtail anglers who needed a terminal knot that would hold under sustained pressure of long fights with large pelagic fish. Its reverse-wrap design causes the knot to lock more tightly the harder a fish pulls.

It has become a standard knot on Southern California party boats among anglers targeting tuna, yellowtail, barracuda, and other hard-fighting saltwater species. If you fish the SoCal waters, this is a knot worth having in your arsenal.

Step-by-Step Instructions

Follow these 5 steps to tie the San Diego Jam Knot. Watch the video above while following along.

Step 1: Thread through the eye

Pass 8 to 10 inches of line through the hook eye and bring the tag end back alongside the standing line creating a generous doubled section.

Step 2: Make 7 wraps away from eye

Wrap the tag end around both lines 7 times working away from the hook eye. Unlike the Clinch, you wrap away from the eye.

Step 3: Thread through the eye loop

Bring the tag end back and pass it through the small loop formed at the hook eye. Pull snug but do not fully tighten.

Step 4: Thread through the big loop

Take the tag end over the wraps then pass it through the large loop created between the wraps and hook eye. This is the defining Jam step.

Step 5: Wet and tighten

Wet thoroughly. Pull tag end and standing line simultaneously while holding the hook firmly. The wraps compress tightly. Trim to 1/8 inch.

Pro Tips

  • 7 wraps works best for most line weights
  • Final thread-through goes over the tag end then through the big loop
  • Pull tag end and standing line together to tighten
  • Named after the San Diego tuna fleet — proven on big fish

Common Mistakes

  • Wrong direction for the final thread-through
  • Too few wraps — use 6 to 7
  • Not wetting before the final tighten
