Disadvantages

Not the best for big game applications.
Is the Seaguar Knot the best option for big game? Most likely not. While this knot is sturdy and easy to tie, it may not be the ideal choice for big game applications. It’s like trying to climb a mountain on a bicycle; it’s not impossible, but there are better solutions.
Not great with braid
Next, let’s talk about braid. When it comes to braid, we prefer to use more wraps in the loops, so this might fail compared to a six-turn Surgeons loops.
Not designed for dissimilar diameters
Another consideration is the diameter of your lines. The Seaguar Knot is not designed for dissimilar diameters. It’s like trying to fit a square peg into a round hole – it’s just not a good match.
Not slender
Finally, if you want a slim knot, the Seaguar might not be your first pick. It’s like picking a large rucksack over a slim one – both can carry your belongings, but one takes up significantly more space.
Despite these limits, the Seaguar Knot is a solid choice for a variety of fishing situations. In the following section, we’ll look at tying tips and different alternatives to the Seaguar Knot.
Seaguar Fishing Knot Tying Tips

Learning to tie the Seaguar Knot is like learning a new dance. It may appear difficult at first, but with a few pointers and some practice, you’ll be whirling around the dance floor—or, in this case, casting your line—in no time.
- Give Yourself Room to Move: Just like you need space to dance, you need enough lines to tie your Seaguar Knot. It’s like having a long, flowing ribbon to swirl around—the more, the merrier.
- Keep It Smooth: Have you ever tried dancing in sticky shoes? It’s not comfortable. The same is true when tying a knot. Moistening the lines before tying helps slide it into place. You can use chapstick, water, or spit to lubricate the line.
- Trim the Excess: Trim any extra tag ends after securing the knot. It’s the equivalent of chopping off a lengthy dress so you don’t trip on it while dancing. It’s best to keep everything neat and tidy.
- Quality Matters: Using frayed or damaged lines will jeopardize your line integrity and may result in poor performance. Before you begin tying, always double-check your line.
- Match Your Line and Leader Size: We don’t recommend varying your main line and leader size. The Seaguar knot is intolerant of radically different diameters.
- Practice Makes Perfect: Practice is key when learning to tie the Seaguar Knot. The more you practice, the more natural it will feel, and the quicker you’ll be able to tie it.
