Water Knot – How to Tie a Water Knot


A water knot is one of the most important climbing knots to learn. It joins two webbing ends, resulting in having two overhand knots. Aside from climbing, it is also used for fishing. With this type of knot, you can combine two wet fishing lines, and will let you form a stronger line. 

While water knots are known for being strong and reliable, this depends on how you make them. One wrong move can compromise the overall structure. To do this knot right, keep on reading and learn from the tips we’ll share. 

What is a Water Knot? 

Also called a tape knot, grass knot, ring bend, or overhand follow-through, it is two overhand knots. For many outdoor enthusiasts, this is recognized as the most useful webbing knot. 

While it is primarily used for webbing, you can also use the tape knot for a rope. Doing it on a rope will require a slightly different procedure since you are dealing with around material. 

A Step-by-Step Guide 

To do water knots correctly, here are the simple steps that you should follow. 

Start with an Overhand Knot

The first thing to do is to tie an overhand knot. This is the foundation of the knot, so you must do it properly to form strong support. 

  1. Start by forming a loop. 
  2. Insert the top rope inside the loop you have initially created. 
  3. Pull the end of the rope and tighten until you secure a knot. 

Tie the Water Knot

Now that you have the foundation of your webbing knot, follow these steps. 

  1. Insert the tape or the webbing inside the loop of the overhand knot you initially made. 
  2. Trace the initial knot. By doing this, you are doubling the first knot. Make sure that the second tape or webbing lies flat. 
  3. Cinch the knot, making sure that the tail is at least 10 centimeters. 

Tips and Tricks 

Over time, the water knot can loosen. This will weaken its hold. Through repeated loading and unloading, the knots can slacken. The easiest solution is to pull the webbings to tighten. 

The end of the webbing can be prone to creep. To prevent this from happening, consider duct taping the end. This will also help to make the end look neat. 

If there is an obstruction or snag, this can result in catching the outer strap and loosening the knot. A good way to prevent this is by using long tails. 

Uses and Applications 

One of its best uses is when you are trying climbing ropes. You can use this when forming a grommet, which will be useful in a variety of climbing applications. 

Aside from making a sling, you can also use it for extending the webbing. 

Tying this knot will also come in handy for rigging, making it useful for those who would like to learn how to rappel. This will be crucial in preparing an anchor. 

When you are building a hammock, the tape knot will also be useful. 

It is also a good dropper knot for fly fishing. 

Water Knot Alternatives and Variations 

Some alternatives and variations can be useful in various situations. If the load isn’t heavy, such as when you have to hang fruits or other light objects, the flat overhand bend can be a better choice. Alpine butterfly, double fisherman’s, and Figure 8 knots can also work depending on the intended application. 

A variation of this type of knot is a ring bend. This is done in the same steps as mentioned earlier. The difference is that you are using a round rope instead of a webbing. 


The best thing about this type of knot is that it is easy to make. As noted earlier, this is an overhand knot and tracing the initial knot to have a reinforcement. Another good thing is that this knot has little bulk as it is almost flat. However, when you use a rope instead of webbing, this will be bulkier. 


One of the biggest drawbacks of the tape knot is that it can easily loosen, especially with repeated loading and unloading. Pulling the ends tightly is the easiest solution to this problem. The right length of the tail will also address this issue. If possible, avoid cyclical loading with this knot. After long exposure to weight and pressure, this can also be tighter. This will make the knot difficult to undo.
