The ability to tie various knots is an essential task that all sailors are required to know as part of regular shipboard life. As a part of your Basic Naval Cadet training we will be introducing you to
some of the knots that are used on a regular basis onboard a Navy vessel.
For the purposes of this lesson we will be covering the purposes for 8 knots as well as how to tie these knots and what the finished result should look like. The knots we will be learning are as follows:
| 1 |
Mooring Hitch |
| 2 |
Round Turn and Two Half Hitches |
| 3 |
Square Knot |
| 4 |
Sheet Bend & Double Sheet Bend |
| 5 |
Figure of Eight |
| 6 |
Clove Hitch |
| 7 |
Cleat Hitch |
| 8 |
Bowline |
Mooring Hitch
A Mooring Hitch is a temporary knot that can be released quickly.
It can be used when you need to moor a ship alongside a dock or another vessel for a short period of time as it can be quickly released and is more secure than other temporary knots commonly used in the civilian world such as the Slippery Hitch which, while easier to tie, is not nearly as secure.
This knot will hold fast under tension but will quickly release with a tug of the free end of the rope.
The following is a diagram of how to tie a Mooring Hitch:
The finished product should look something like this:

Round Turn & Two Half Hitches
A Round Turn & Two Half Hitches is ideal for attaching a mooring line to a dock post or ring.
This is the knot commonly used to secure a ship for any long period of time. As you can probably already
tell by the name, this knot is made of a round turn which as the diagram shows you is actually really 2 turns and then two half hitches.
It is actually very easy to do, and the following diagram will show you the 9 steps from start to finish on how to tie a round turn & two half hitches:

Square Knot
The Square Knot, also commonly referred to as the Reef Knot, is actually a concept you are already aware of, whether you know it or not (that is unless you don't know how to tie your shoes).
While this is not the most reliable knot to use as a bend it is a knot that teaches you the fundamental process of tying a half knot or half hitch which comes in handy when tying other more complicated knots such as the Round Turn and Two Half Hitches.
The following diagram shows how to tie a Square Knot:

As you can see above it is in fact just like tying your shoes, only without the bow.
So since you already know the basics and can do a square knot without even knowing you could, the rest of these knots should be pretty easy stuff right?
Sheet Bend
The sheet bend is a knot designed to tie together two pieces of rope.
You can use this to tie together rope of the same
or different sizes, so regardless if the ropes are of the same thickness this knot will work for you if you want to tie two pieces of rope together.
The following is a diagram of how to tie a sheet bend:

In the second part of the above diagram you see a double sheet bend, which is used when one rope is markedly thicker than the other.
The bitter end of smaller rope can be taken twice around the bight in the larger rope to create a double sheet bend.
If you have successfully tied this knot then both ends will lie on the same side of the knot. If the ends are on opposite sides of each other then you have not tied the sheet bend correctly and while it may seem to hold it is much less reliable.
Figure Eight
The figure eight is designed to provide a stopper knot to prevent a line from sliding out of sight for example: up inside the mast).
The biggest benefit of this knot is that even after it is jammed tightly against a block it can still be undone easily.
The downside is of course the same as the benefit, because it can be undone easily, sometimes it can fall undone on its own and has to be retied.
Since it is easy to tie this is not a big deal. The following is a diagram of how to tie a figure eight knot:
Clove Hitch
The Clove Hitch is a knot that is considered to be one of the most essential for sailors to learn.
It can be used as a binding knot however it's most effective as a crossing knot the reason being it has a tendency to slip when you are loading only one end.
It requires a load on each end to work properly and when this is the case it can be very helpful as it allows for the running end of the rope to be adjusted.
Now the traditional way to tie a clove hitch is by forming two loops as is shown in the diagram below:
However when it is not possible to form two loops you can tie it on the end.
The diagram below will compare each method so you can see the difference:
Cleat Hitch
Thr Cleat hitch is designed to secure a rope to a cleat which secures the boat to a dock.
It is a relatively simple knot using boat rope (which when aboard ship is referred to as a line) to form a figure eight shape around the cleat to keep the boat in place.
To tie the knot you need to make a complete turn of rope in one direction around the base of the cleat, followed by a complete turn of rope in the reverse direction.
You then make a half hitch around one wing of the cleat to finish the knot.
The friction created by the two complete turns ensures that the half hitch does not pull tight and jam on you. Sound complicated?
It's actually really simple, as shown in the diagram below
Bowline
The bowline makes a secure loop at the end of a piece of rope. It has many applications, the most common being to fasten a mooring line to a ring or post. In layman's terms it is used to make a temporary loop at the end of a line.
What's great about it is that under load it doesn't slip or bind and when there is no load it can be easily and quickly untied.
The only downside is that it cannot be tied or untied when there is a load on the standing end.
Bowlines can also be tied using one hand which makes them an essential knot to know if you are injured or your other hand is busy holding onto the line or the boat.
The best way to explain how to tie a bowline is by using the rabbit scenario, as shown in the images below:
- Here is the rabbit hole
- Out comes the rabbit
- It runs around the tree
- And hops back into the hole
There you have it! A bowline!
Now if the rabbit story doesn't help you then. I also have a diagram below of how to tie a bowline, or you can of course refer to the video tutorial on your left.
