Quick Answer
Collect rainwater safely while on a life raft by using a dedicated rainwater collection system, such as a canopy or tarp, and a clean water container, like a collapsible water tank or a plastic drum, to minimize contamination and prevent bacterial growth.
Rainwater Collection System
When collecting rainwater on a life raft, it’s essential to use a dedicated rainwater collection system to minimize contamination. A good option is a canopy or tarp that covers the life raft, allowing rainwater to collect in a designated area. This can be achieved using ropes or elastic cords to secure the canopy or tarp over the life raft. A 2x2 meter canopy can collect around 20 liters of rainwater in a 30-minute moderate downpour.
Clean Water Containers
Once the rainwater has been collected, it’s crucial to store it in a clean water container to prevent bacterial growth and contamination. A collapsible water tank or a plastic drum with a capacity of 10-20 liters is an excellent option for storing rainwater on a life raft. Make sure to clean the container thoroughly before use and regularly check for any signs of contamination.
Desalination and Signaling Rescue
While rainwater collection is the primary source of water on a life raft, it’s also essential to have a plan for desalination and signaling rescue. In the absence of rainwater, a manual desalination system or a solar still can be used to extract water from seawater. Additionally, always carry a signaling device, such as flares or a mirror, to alert potential rescuers and increase the chances of being rescued.
