In the unlikely event of finding yourself alone in the open sea in these times, you should have the minimum knowledge of the basic survival skills. There are several rules that are not that difficult to remember, but can save your life in the long run:
Calm down. This is the first rule of any stressful situation. Don’t panic as that will make you lose the necessary rhythm of breathing, so calm down.
Choose the right swimming style as you will still have to move in the water. Remember that in calm waters it’s better you swim on your back while if the waves splash around you, it’s better to swim on your belly.
Look for something that floats. If you are in the open sea as a result of a shipwreck or an airplane water landing there must be plenty of things around you that float. Try to see if there is any emergency raft or boat.
Don’t take off your clothes. Keep your clothes on as they will save you from direct sun rays. Create a shade and stay in it.
Decide what you’ll eat. You need energy and food. Divide whatever you have in small portions. Try catching seaweed and don’t eat spoiled food no matter how hungry you are.
Either from rain or artificially obtained, water is vital. Keep in mind that you should never drink seawater. You can condensate, for that you will need a box, two containers, waterproof material and weights. Pour seawater inside one container and place the other one in a box next to it. Secure the piece of waterproof material above both and put a weight over the empty one. Soon the container will be filled with fresh water.
Save yourself properly. If you have no idea where you are, rely on the current, it will carry you to the land. Don’t rush into the water if you see a ship in the distance and don’t try to signal by fire.
