Floating is an important self-rescue technique for water survival to keep you afloat. It can be used while waiting for help to arrive and as resting position when swimming to safety.

In this session we practice floating skills in deep water and learn how to make a float with a buoyant aid or with our clothes, swim with that float, deflate and inflate the float again.

Wearing full gear, step into shallow water at the shallow and walk to shoulder deep water. Then lift your legs up and start floating.

Both the drownproofing sequence and treading water use sculling. This is a rhythmically controlled motion of the arms and hands to manipulate the water for upward lift and keep the body vertically afloat.

A common sculling action is the figure eight. With the fingers together and palms facing downward, draw a figure eight with each hand, pushing the water downward and outward during the motion. Keep the arms slightly bent in front of the chest. Use a minimum of effort to avoid excessive fatigue.

This means simply lying flat on your back with your feet relaxed and slightly apart. Your arms are at your sides moving slowly side-to-side. If you feel yourself sinking, raise your chin putting your head further back in the water. The key to effective back floating is to relax your body. Very little motion should be required to remain afloat.

Get into a sitting position in the water. Rhythmically move your arms back and forth at the same time you move your legs like on a bicycle. Care should be taken to keep the head above water as much as possible.

Use anything that floats and is big enough to support your weight. A buoyant aid like a bucket or bag or a canister is a good start.

Trap as much air as possible in the buoyant aid and hold it to your chest so you can remain afloat. The skill is in holding your float so the air doesn't escape.

Another method is to use larger floats, like rescue rings, foam mattresses, and the like. See if you can get on top of them. Keep your balance and relax on top of the float.

A waterproof rucksack makes a great float. You can use it it to swim across to an island, change into dry clothes, have a meal and spend the night in a dry sleeping bag. Comes the morning your wet clothes have dried so you can pack up and swim back or onwards to another island.

Waterproofing Your Rucksack

If properly waterproofed, all rucksacks have enough flotation potential to keep even the largest camping equipped survival swimmer afloat. Therefore, a rucksack becomes an asset during water survival training. You can waterproof your rucksack with plastic bags, or the more robust canoeing bags. To waterproof and secure the rucksack, use the following procedures:

Arrange all gear neatly inside a plastic bag with the most commonly used items on top. Fold or roll clothing. Press the bag tightly to squeeze out excess air. Use a series of folds to form a watertight seal of the bag, and keep the folds in place with a rubber band. Place the bag inside the rucksack. Close the drawstrings of the rucksack as tightly as possible.

Place the sleeping bag inside a plastic bag, and press out excess air. Place this inside a waterproof bag. Tie the waterproof bag closed as tightly as possible, ensuring that the plastic bag is entirely inside. Securely attach the waterproof bag to the back of the rucksack under the closing adjustment straps.

Securely attach the sleeping mat to the top of the rucksack under the closing adjustment straps. You should now have a waterproof bag that will float. You can either wear it on your back or tow it behind you.

Single Rucksack Exercise

Attach a canoeing helmet to the rucksack. Wearing full set of clothes, enter the pool at the deep end using the stride entry. Remove the waterproofed rucksack, put on the helmet, and push the rucksack the length of the pool to the shallow end using the frog or scissor kick.

Two Rucksack Exercise

Fully clothed, enter the pool at the deep end using the stride entry. Remove the waterproofed rucksack from your back. Grab your partner's rucksack. Swim the length of the pool to the shallow end pushing one rucksack while towing the other.
