Scuba Diving Knots


Essential KNOTS for Scuba Divers


Knots - they're all around us, all the time. They are so fundamental to daily life and it's easy for us to forget just how important they are. From tying our shoelaces to the invention of woven materials; imagine a world where clothes would not exist. For thousands of years, construction of buildings has relied upon knot tying.


There are so many useful knots out there, and certain types are best suited for different situations such as climbing, sailing, or stitching. So if there's one useful skill when it comes to diving and boating, it's knowing your bends from your hitches. One day you might find yourself needing to secure a lift bag to an object, tie a line to a surface marker buoy, or attach a drift line to the boat.


If you're in a hurry, one well placed knot will be far more reliable than a tangled stack of twisted rope. Therefore it pays to have a few simple ones in your arsenal, especially when someone's safety may one day rely on it.


You May "Knot" Know....


The Incas used a system of knots as their written language. The necklace-like “documents” are thought to have encrypted historical events and told stories, although the code has never been deciphered.
The way a rope feels is called its hand. A looped bundle of rope is known as a hank. A bend ties two ropes together and a hitch attaches to a stationary object. A section of slack rope that bends without crossing is called a bight, but if it crosses it's a loop. Make a twist on a loop and you have yourself an elbow!
In addition to humans, gorillas and weaver birds tie knots. However, I've never seen either of them wearing a harness or sailing.


Essential Knots for Diving


Here's a few that are helpful to know. If in doubt, just remember, "if you can't tie knots, tie lots!"


Reef Knot


One of the simplest knots that can be used for joining two ropes together in a hurry. A simple “right over left and under, left over right and under”. Used by itself, it doesn't form the most reliable knot as it has a tendency to slip under a moderate load. It is important, however, as it forms the basis for many more complex knots.

A good multi-purpose knot, which forms a secure loop in the end of a rope. As it does not slip, it can be used for tying boats to mooring lines, or even joining two lengths of rope together. It can be tied easily, can withstand a load, and be released quickly. The downsides to this one is that it can easily be shook undone if it's not placed under stress, and is not possible to tie or untie when the rope is too taut.

Sheet Bend (a.k.a Beckett Bend or Weaver's Knot)


The main purpose of a bend knot is to join two different types of rope together, but also works just as well if the ropes are of the same thickness. Its name comes from historic times in when weavers used it in textile mills, having to join threads together. In sailing, it's used for joining ropes to sails, or lengthening a drift line with two ropes.

A quick, convenient and strong stopper knot on the end of a rope. This type of knot will prevent a knot slipping through a hole, so can be used on the tail end of a weaker knot to make a stronger combination.

Want To Become an Underwater Knot Master?


There is a course that you can take that will teach you how to perform these knots underwater but also put them into practical use. The Search and Recovery course is designed to build your skills so that you are not only able to tie the correct knot for the object you are about to move. But also teach you how to plan and carry out search patterns so you can locate missing objects.


You will also be shown the correct techniques to lift objects from the bottom to the surface safely and efficiently. The skills you learn on this course or even as an adventure dive whilst completing your Advanced Open Water course will help to make you a better scuba diver in the future.
