Hey BDers, with your bountiful collective wisdom,

I have a thoughtful, probing question. :rolleyes: Namely, what benefit is there in using a double San Diego knot? Since you end up cutting all ends except your main line, it seems that all you get out of the deal is just a single San Diego with a bit of extra cushion from a short segment of line interwoven with the knot. Can it possibly make that much difference? Thanks in advance, ladies and gentlemen.

Good fishin'!

All I know is that's all I used fishing Yellows in the Sea of Cortez, and I never had a knot fail. Biggest yellow 32 lbs...and some released bycatch Totoaba that that was well over 80 lbs.

It was on 50 lb line.
I only use it on 40 lb or more, mainly when jig fishing.

Which one? Too many....
The benefit is the 2nd wrap around the hook (or swivel). You now have 2 loops instead one 1 loop around the eye of the hook. But you have to make sure the 2 loops are not crossed.

Same concept with a Trilene knot.

What’s the reason? The guys who have seen every knot perform and are paid to hook us up to cows say so!

Every knot has a purpose and every knot is going to place strain on the main line in some fashion. The purpose of the San Diego is terminal strength over the benefit of better action or the smaller size other knots can provide. The strongest knots spread the load over a larger area of the main line and connection point. Doubling the San Diego spreads the strain over two lines and in doing so relieves some of the pressure and chaffing the cinch will inevitably place on the main line.

For me, it is also faster and easier to get a good clean knot with heavier line when I tie a double, mainly because it requires less wraps to get a similar size knot.

    There are less bulky easier to tie knots that only have one tag end and are doubled through the eye... like the trilene or the springer/spangler (modified Jansik Special). Personally, I have trouble getting the Trilene to cinch down properly without "trauma" to the knot. So, I prefer the Spangler on line above 60#.

    if ur that interested (which is cool), i’d try tying various knots to 2 rings and see what breaks/holds when you pull. for example i realized duble uni was no stronger than single for line i was tying. so it was logical to use single uni bc easier/faster. and san diego jam stronger than uni. it’s hard to argue with results of ur own experiments.

    I think I have heard some place that if one has made it one should test it, I find it works. Results from the brother in law of an uncle I met on the dock don't do it for me.

    On a trip down to the lower, lower zone on the Rooster, back in ‘09…

    Had borrowed a kite outfit from Billy Casper Jr, kind enough to have dropped it off in the office for me. Nick put on a 200# mono topshot for me and when it was my turn I asked for help connecting it to my leader for the Flyers we had. He tied a double San Diego. 200 pound monofilament, double San Diego!

    I’ll use it for jigs mostly, when I have tied a Surgeon’s knot for a loop, 50 lb for heavy jigs like YoYo iron or Wahoo jigs, 40 lb for Surface Iron.

    I have had the loop of the knot break where it rested against the hook in an extended fight with relatively light line. A doubled loop may have helped. Hindsight with experience is 20/20.
