There are a lot of knots that sailors use, but the most important knot is probably the tying of a square knot. This basic knot is used to tie multiple ropes together, to form a loop, and to secure something before tying it off. So what’s the best way to learn how to tie it? With this quick and easy tutorial, you’ll be able to tie the snell knot in no time!

What is a Snell Knot?

The Snell Knot is a knot used inautical navigation and is also known as the Uni Knot. It is named after Samuel Snell, an American naval officer and inventor who developed the first practical navigation system. The knot is composed of two turns of rope around a spar or post. When tied, the ends of the ropes are pulled tight and the middle of the knot bulges out from between the ropes.

How to Tie a Snell Knot?

The Snell knot is a knot used to attach a line to a post or other object. It is similar to the reef knot, but the ends of the line are not crossed. To tie a Snell knot, start by making a loop with the line. Make sure that the loop is large enough so that the end of the line can fit through it. Then, make a semi-circle with your thumb and first two fingers. Place this semi-circle over the loop on the line, and twist it clockwise so that it forms a hook. Now, pull the line through the semi-circle, and tighten the hook by pulling on both ends of the line.

  1. Pass the tag end through your hook’s eye, parallel to the shank.
  2. Make a small loop.
  3. Wrap the mainline with the tag end and run away from the eye 5 to 7 more times.
  4. For braid and fluorocarbons, you will need 7-10 wraps.
  5. You will need to wet the knot and secure it with a securing device.
  6. Trim the tag at the end.

How toUntie a Snell Knot?

If you are ever in a bind and need to untie a snell knot, there is an easier way. The Uni (or Overhand) version of the snell knot can be undone in just a few steps. Follow these steps:

  1. Make a loop with the rope around the object or person you want to tie it to.
  2. Cross the rope over the top of the loop and tuck it underneath.
  3. Pull the loop tight until it forms a U-shape.
  4. Hold on to the two ends of the rope and pull them apart until the U-shape pops open.

Useful Info for Cruising Sailors

The snell knot is a versatile knot used for tying a variety of ropes together. The Uni version is the simplest and most common way to tie the knot. Here’s how to do it:

  1. Take the end of the rope you’re tying and place it over the middle of the rope you’re tying.
  2. Hold on to the ends of both ropes and tuck them underneath the middle one. This will create a “bunny ear” shape.
  3. Take the left hand rope and make a loop, or “bunny ear,” with it. Make sure that the end of this new loop is pointing towards you.
  4. Now take the right hand rope and make a loop, or “bunny ear,” with it as well. Make sure that the end of this new loop is pointing away from you.
  5. Cross these two loops, or “ears,” over each other, so that they are now in front of each other. The top loop should be on top and the bottom loop should be underneath (see picture below).
  6. Take the bottom loop and put it over the top loop, making sure that it hangs down inside.

The Snell Knot in Braid and Fluorocarbon

The Snell knot is a versatile knot that can be used in both braiding and fluorocarbon rope. It is named after the American naval officer and physicist, Edmund Snell. The knot is easy to tie and makes a strong, secure knot.

To tie the Snell knot in braid, first tie a basic knot using two strands of rope. Make sure the ends of the ropes are opposite each other. Cross the middle of the ropes over the top of the first knot. Now tuck the bottom of one rope under the top of the second rope and pull tight. This creates a loop. Make another loop by doing the same thing with the other rope. The two loops should now be close to each other but not touching.

Cross the middle of the ropes over each other again and re-tie them into a basic knot. You’ve now tied an “S” shape with the ends of both ropes sticking out of either side. To finish off, take one end of each cord and make a “bunny ear” loop with it. Put these loops over your head and pull tight to close off the ends.

Why Rely on Snell Knot?

The snell knot is one of the most versatile knots in all of fishing. It can be used as a leader knot, to attach a lure to a fishing line, and more. The snell knot is also known as the Uni knot because it can be tied in either left or right hand directions.

What Happens When Snell Knots FAIL?

When you tie a snell knot, it’s important to make sure it doesn’t fail. If it does, you might be in for some trouble! Here are four ways a snell knot can go wrong:

  1. The line becomes twisted and tight. This can cause the knot to become difficult to untie or even impossible.
  2. The knots slips off the lanyard. If this happens, the knot will become tangled in the lanyard and may not be retrievable.
  3. The loop forms on one side of the lanyard, preventing it from being tied properly on the other side. This can result in a poor knot that is difficult to untie or even dangerous if left attached to something dangerous.
  4. The knot becomes too tight and cuts into the hakapai or body of the fish. With any type of fishing line, it’s important not to over-tighten your knots in order to keep them from cutting through your bait or lure.


If you’re looking to learn how to tie the Snell knot (also known as the Uni knot), this tutorial is for you. The Snell knot is a versatile knot that can be used for a variety of purposes, such as tying ties and laces, securing bags and straps, or temporarily fastening an object together. In this tutorial, we will show you how to tie the Snell knot using the uni version—a simpler but still effective method that is perfect for beginners. Happy tying!
