For in- and offshore trolling with braided mainline, there’s no stronger knot than the Bimini Twist.
Designed around the needs of anglers chasing tuna, marlin, wahoos, and sailfish, it doubles the mainline into a secured loop, resulting in a very strong anchor for your leader connection. Most anglers then use a Bristol or Yucatan knot to attach the leader, yielding a very robust connection.
Often reaching the magical 100% knot strength, the Bimini Twist is one of the most well-known and well-used knots in the salt.
Bimini Twist Knot - Good Knot for Joining Braid to Fluoro Leader
Utility: Very Good

Nylon monofilament bites on itself really well, creating plenty of friction to hold a knot tight. And the good news is that the Bimini Twist works great in heavy mono mainlines, whether you’re just tying-off to a big lure or running an even heavier-gauge leader.
The Spectra and Dyneema fibers woven together to create braided lines are slick stuff, and they slide rather than bite against themselves. That tends to drastically reduce knot strength as your line prefers to pull through rather than hold.
Fluorocarbon exhibits a similar issue in that it’s a very hard material. Unable to deform easily against itself, it, too, prefers to slide rather than bite.
The good news is that the Bimini Twist is an ideal knot for braid, and its clever design creates a huge surface area to generate friction and distribute load. Tied well, there’s no stronger knot out there.
But there has been some misinformation about the Bimini Twist that continues to be repeated in the sportfishing world.
In 2007, Sportfishing Magazine erroneously reported that the Bimini Twist was stronger with fewer twists. This continues to be reported by word of mouth on popular fishing message boards.
It’s not true!
Subsequent re-testing has revealed that mistakes were made in the initial article, and Sportfishing Magazine did the right thing--reversed their claim--and now recommends 20 to 30 twists.
Since then, repeated tests have confirmed that more is better.
The Bimini Twist is one of a family of loop or “doubling” knots in that it creates a long loop that’s secured by repeated twists.
This has one chief advantage:
The Bimini Twist’s ability to hold in braid is the stuff of legends, but it can fail if you make these two common mistakes:
The Bimini Twist’s strength comes at a price.
