Can survival training enhance your chances in open water?

Open Water Navigation

Survival in open water often begins with navigation. To increase your chances of being rescued, it’s crucial to have a basic understanding of celestial navigation. Using a sextant, you can determine your latitude by measuring the angle between the sun or a star and the horizon. Knowing your latitude, combined with your estimated longitude, can help you determine your position. For instance, at noon on a sunny day, you can estimate your latitude by measuring the angle between the sun and the horizon and using a trigonometric table. This technique allows you to narrow down your location and potentially find land or a shipping lane.

Water Purification and Rationing

When cast adrift in a life raft, access to clean drinking water is vital. Desalination is a viable option, but it requires a manual pump or solar still, which can be time-consuming. To conserve energy, it’s best to ration your water intake, aiming to consume no more than a liter per day. If desalination is required, consider using a solar still, which can produce approximately 2-3 liters of water per day. It’s also essential to store rainwater and condensation from your body for supplementary hydration.

Shark Avoidance and Signaling

When in the water, shark avoidance techniques are critical for survival. To minimize the risk of shark attacks, avoid wearing shiny jewelry, enter the water feet first, and avoid wearing perfumes or soaps. When swimming, stay close to your life raft and avoid splashing or making loud noises. To signal for rescue, use a mirror or any shiny surface to reflect sunlight towards any potential aircraft or ships during the day. At night, use flares or a flashlight to signal your location.
