Even if you find yourself after a disaster alone in a rescue craft, keep a daily record. It takes your mind and helps you navigate events and surroundings. If not one, then first write down the names of those who are with you, the date, time and place of the disaster, weather conditions, salvage equipment and daily record landmarks and events.
Protection against weather conditions when surviving on water, behavior in a rescue vehicle.
In cold climates.
If the water is cold, it is important to get out of it as soon as possible. You will have to withstand the cooling effect of the wind, especially when you are wet. Keep the boat or boat as dry as possible. Scoop out all the water and make a screen and / or canopy against splashes if you can find material for this. Dry all wet clothes, and if there is no dry change of clothes, squeeze the maximum amount of water and put on clothes again.
In hot climates.
Remove excess clothing while in a rescue vehicle, but at the same time let the body remain closed. In direct sunlight, always keep your head and neck covered so as not to get a burn or sunstroke. Protect your eyes from bright sunlight with improvised safety glasses. Wetting clothes in the afternoon with sea water will help to somehow cool the body, but before sunset, be sure to be dry at night, it can be very cold and remember that in the tropics, night falls very quickly. Do not forget that prolonged contact with salt water can cause irritation, sores on the skin. Since the air expands when heated, when it is very hot, bleed some air from the inflatable boat. You will have to open the valves. In the evening, when it gets cool, pump up the boat again.
Rescue duty and surveillance.
If you have a group, distribute the duty. Surveillance on a rescue vehicle should be carried out constantly even in the dark. Each shift should not last long to avoid overwork and reduced attention. It is better and more efficient that each day on duty a little more than a few times than once a long period. The duty officer is charged with the duty of monitoring the appearance of a ship, aircraft, land, as well as algae, schools of fish, birds, debris. They should also inspect the craft in terms of punctures, breakdowns, etc..
Signs of proximity to the earth.
When there is no shore in sight, there may be some signs of the possible proximity of the earth and the likely direction in which it is.
Cumulus clouds in clear sky are likely to have formed above the ground. In tropical seas, the greenish tint on the bottom of the clouds is the result of the reflection of sunlight from the surface of the shallow water above the coral reef.
A lonely bird is an unreliable sign of near land, and windy or stormy weather can take the bird far away, but few birds sleep on the water or fly more than 10 kilometers from the ground. Usually they fly away from the coast until noon, and return in the afternoon. A continuous bird cry is usually a sign of the relative proximity of the earth..
Fin, coconuts and other floating vegetation are often a sign that the coast is close (although in principle it could cross the ocean).
The movement of the sea surface and its color.
The swell pattern may indicate the proximity of the earth. A change in its direction may be caused by the movement of the tidal current around the island. The prevailing winds form a swell, and it is smaller if the water is protected by the earth. If the wind is constant, and the swell and waves are reduced, we can most likely assume that the earth is located on the windward side. Silt in seawater most likely came from the mouth of a large river.
