How to Tie a Seaguar Knot

If you’re looking for a fishing knot that can join fluorocarbon and monofilament lines together quickly, then you need to learn the Seaguar Knot. It was first introduced by the Seaguar line company and is a solid non-braid line-to-line knot.

Tying the Seaguar Fishing Knot

  1. Overlap your monofilament and fluorocarbon lines and form a circle.
  2. Twist the loop so that it wraps two to three times (three if you use a braid). Some anglers use their two fingers in the loop to make the twist easier.
  3. Place the leader line and the tag end of the mainline through the loop above the wraps.
  4. Pull the two ends of the knot, moisten, then fully cinch down.
  5. Clip the tag ends of the monofilament and fluoro, and you’re done.

Seaguar Knot vs. Double Uni Knot

The Double Uni can be used with braid, whereas the Seaguar should only be used when tying mono to fluoro.

Seaguar Knot vs Surgeon’s Knot

The Surgeon’s Knot is a reliable alternative to this knot. Most fishermen like to add an extra overhand knot to create triple Surgeons for added strength.

Advantages and Disadvantages

  • These fishing knots are reliable for attaching tippets to your leaders quickly.
  • The Seaguar Knot is quicker to tie than an FG Knot or John Collins Knot if you’re in a hurry.
  • It’s likely not the best for big game applications.
  • When using braid, we prefer to use more wraps in the loops, so this might fail compared to a six-turn Surgeons loops.
