Episode Show Notes

The San Diego Jam is a tuna-fishing knot out of California that you can tie with a single strand or a doubled strand, and in this test the double came out stronger. Tied straight to the swivel with Daiwa J-Braid 30 pound braid, the single broke at 26.91 pounds and the double at 30.93, just over 100 percent. In this How 2 Tuesday I tie both versions step by step and put them on the machine to settle which is stronger.

Frequently Asked Questions

Is the single or double San Diego Jam stronger?

In this test the double San Diego Jam was stronger. Using Daiwa J-Braid 30 pound test braid tied straight to the swivel, the single San Diego Jam broke at 26.91 pounds and the double broke at 30.93 pounds. The double came in just over 100 percent of the line rating, so doubling the line over before you tie the knot gave it a little more strength. Both are excellent connections, but if you want every bit of strength, the double is the winner in this test.

What is the San Diego Jam knot used for?

The San Diego Jam came out of California for big game tuna fishing and it has taken the country by storm. It is one of the most important and strongest knots we use for tying line to a swivel, lure, or hook. Bass fishermen are using it, saltwater fishermen are using it, it is being used all over. You can tie it with a single strand or with a doubled strand, and both versions are strong, reliable connections to terminal tackle.

How do you tie the single San Diego Jam?

Run a single line through your swivel or lure and hold the lure in your right hand. With your left hand, make a loop around your middle finger and keep it there, then wrap the tag end around both strands of line about ten times. That leaves a loop right at the swivel, like a clinch knot. Pass the tag end through that loop, pull your finger out and pass the tag through the finger loop, then pull tight with the standing line, snug it down hard with pliers, and trim at the knot.

How do you tie the double San Diego Jam?

Double the line over and run the doubled line through the swivel or lure. Hold the lure in your right hand and wrap the doubled line around your middle finger just like the single. Then wrap the doubled line around all four strands, leaving a loop next to the swivel. Pass the doubled line through that loop, remove your finger, and pass the tag through. Pull down slowly on the standing line, then tighten both standing lines really tight with pliers and cut the correct tag end, or you start over.

Why do you need pliers to tie the San Diego Jam?

Pliers let you cinch the knot down really, really tight, which is where this knot gets its strength. A knot will slip before it breaks, so getting it as tight as possible while you are still in the boat is what makes it strong. On both the single and double you snug the wraps with the standing line first, then finish by pulling everything down hard with pliers before you trim the tag end right at the knot.

What line did you use to test the San Diego Jam?

I tested both versions with Daiwa J-Braid 30 pound test braid tied straight to the swivel, with no leader in between, so the comparison was apples to apples. The single broke at 26.91 pounds and the double at 30.93 pounds. Because the double exceeded the 30 pound rating, it tested just over 100 percent. You can get the results of this test and every knot test we run in the free knot guide linked from the episode.

Why I Tested the Single Against the Double

The San Diego Jam came out of California for big fish like tuna and it has gone all the way across the country, with bass and saltwater fishermen using it everywhere. You can tie it single or double, and the question I get is which one is actually stronger. Rather than guess, I tied both and put them on the scale. I walk through the whole comparison in the episode, so press play in the player above.

How to Tie and Test Both San Diego Jams

Here are the steps I follow for both versions and the test that settles it. I cover the details in the episode.

  1. Tie the single. Run a single line through the swivel, loop around your middle finger, wrap the tag around both strands ten times, pass it through the swivel loop and the finger loop, then cinch tight with pliers and trim.
  2. Tie the double. Double the line over, run it through the swivel, loop around your middle finger, wrap the doubled line around all four strands, pass it through the loop and the finger loop, then pull both standing lines tight with pliers.
  3. Cinch it down hard. Because a knot slips before it breaks, snug each knot as tight as you possibly can with pliers while still in the boat to reach full strength.
  4. Cut the correct tag. Make sure you trim the tag end and not a standing line, or you will have to tie the whole knot over again.
  5. Test the results. Put both on the scale to know the real breaking strength instead of guessing, which is exactly how this comparison was settled.

I unpack each step in the episode. Press play in the player above.

Why Pliers Make This Knot Strong

A knot will slip before it breaks every time, so the whole game is getting it as tight as you possibly can while you are still in the boat. That is why I finish both the single and the double by cinching everything down hard with pliers before I trim. I explain exactly how tight and where in the episode, so press play in the player above.

The Results On the Scale

With Daiwa J-Braid 30 pound braid straight to the swivel, the single broke at 26.91 pounds and the double broke at 30.93, giving the double just a little more strength at just over 100 percent. I break down what that means for your rig in the episode, so press play in the player above.

Final Thoughts From Me

Both San Diego Jams are strong, dependable connections, but if you want every last bit of strength, double the line over before you tie it.

Either way, cinch it down hard with pliers and always cut the right tag end. Press play in the player above.

Tom Rowland Podcast — Episode 910: San Diego Jam vs. Double San Diego Jam (How 2 Tuesday with Tom Rowland)

In this episode: how to tie the single San Diego Jam with ten wraps and a middle-finger loop, how to tie the double with the line doubled over, why you need pliers to pull it really, really tight, and the break test on Daiwa 30 pound braid — single at 26.91 pounds, double at 30.93 — in the exact words spoken.

00:00 · Cold Open

Tom Rowland: If you want everything you need to take care of your boat, StarBright's got the solution. It's called boat care in a bucket. That's right. One three and a half gallon bucket packed with essentials, vinyl bright, deck cleaner, marine polish, a wash mitt, hull cleaner, and boat wash. That one kit will keep any boat clean and protected, but that's just the start. I also use StarBright's salt off, which is incredible for rinsing salt off after a day on the water. Their brushes and cleaning products work just as well on your RV and patio furniture and anything else that lives outside. It is a company that gives back. That's one of the things that I really like about StarBright. StarBright supports marine conservation through Project Sea Safe, and that means a lot to me personally. You're getting performance and purpose. Visit starbrite.com. That's starbrite.com, and get your boat dialed in for the season. From The Seychelles to The Keys, I trust Nikon binoculars to find fish fast. Visit nikonusa.com and upgrade your line of sight. I thought I was covered, but I wasn't. HH Insurance showed me that my old policy did not cover The Bahamas or nighttime navigation, two major gaps that could have cost me a lot. Jake and Landon fixed it fast. They know charter policies better than anyone I've ever worked with. Call (727) 498-5551 or visit hhinsgroup.com and tell them Tom Rowland sent you. Trusted enough to go with me to The Seychelles, my Danco pliers are a staple in my kit. Check out dancopliers.com and build yours today.

01:36 · A Knot That Came Out of California for Big Game Tuna

Tom Rowland: San Diego jam is a knot that came out of California for big game tuna fishing. It has taken the country by storm. It's one of the most important and strongest knots that we use. So there's a couple ways to tie it. You can tie it with a single strand or you can tie it with a double strand. And today, we're gonna find out which is actually stronger. Stay tuned to the end to see the results. This is how to Tuesday on the Tom Rowland Podcast brought to you by Danco.

01:59 · Tying the Single: Ten Wraps Around Both Strands

Tom Rowland: And this is how you tie the single. This is how you tie the San Diego jam single. We're gonna take a single line, just like the knot implies. We're gonna put it through your swivel, your lure, or whatever you're fishing with. And I'm gonna hold this lure or swivel in my right hand. And with my left hand, I'm gonna take my middle finger, and I'm gonna make a loop around that middle finger. I'm gonna pull this loop tight, and I'm gonna keep that loop around my middle finger. And then around both strands of this line, I'm going to wrap this tag end. I go around 10. That seems to be fine for me. Then there going to be, there's going to be a loop right at the swivel, just like you would tie a clinch knot or any other knot like that.

02:42 · Finishing the Single: Through Both Loops and Pliers-Tight

Tom Rowland: Put the tag end through that knot, we're going to take your finger out of this loop here, and we're going to pass the tag end through that loop you created with your middle finger. Now we're going to hold, hook, lure, or swivel, and pull down tight like this. Then I'm going to let go of the tag end, and I'm gonna pull with the standing line right down to the swivel. Then, this is where you need your pliers, and pull this really, really tight. We're gonna trim it off right at the knot because you tightened it down really good. That is the San Diego jam single.

03:24 · Tying the Double: Doubled Line Through the Swivel

Tom Rowland: This is how you tie the San Diego Jam double. I'm going to take the strand of line, and we'll put plenty to work with. Double this line over. I'm going to put this right through the swivel or lure. Then I'm going to change hands here, and I'm going to put the lure or swivel in my right hand. And with my left hand, I'm going to wrap the line around my middle finger exactly like I did with a single. And then I'm going to wrap this doubled line around all four lines.

04:01 · Around All Four Strands: Where the Jam Is Different

Tom Rowland: Then there will be a loop right next to the swivel. I'm gonna take this doubled line, put it right through that loop, and then again this is where the San Diego jam is different. I have that loop. I'm going to remove my finger from this loop that I've created. This tag goes through there. And I'm gonna pull down nice and slowly with the standing line holding just the tag like that.

04:30 · Pull It Super Tight and Cut the Right Tag End

Tom Rowland: Once I get it pretty tight, I'm gonna then go to both standing lines and pull this down really, really tight. This is when you need your pliers again. And then pull this super tight. And, cut the proper one, the tag end. Make sure it's the tag end or you have to do it all over again. Cut this one.

04:55 · Time to Test: Single vs. Double

Tom Rowland: Now it's time to test it. That's the double San Diego jam. San Diego jam knot came out of California for big fish like tunas and it is gone all the way across the country. Lots of bass fishermen are using it, saltwater fishermen. It's being used all over. We tie the single and we tie the double. Which one is stronger?

05:21 · The Results: 26.91 vs. 30.93 Pounds on 30-Pound Braid

Tom Rowland: Today, we tested the single and double San Diego jam with Daiwa Jade Braid 30 pound test braid straight to the swivel, and the results are in. The single broke at 26.91 pounds, and the double broke at 30.93. The double actually gave it a little bit more strength. It's just over 100%.
