What should you do when it starts raining on a life raft?

When it starts raining on a life raft, allowing the first few minutes of rain to wash away the salt is the most appropriate action. Rainwater can provide a source of fresh water that will help to dilute the salt that may have accumulated on the raft and survives from the sea. After being exposed to seawater, any salt residue can be harmful if ingested, making this step important for ensuring that the raft is safe and comfortable to use.

By utilizing the initial rain to rinse away salt, you are improving the living conditions on the raft. Furthermore, collecting rainwater for drinking after the initial wash can supplement your fresh water supply and is often more palatable. This method represents a practical approach to survival in a challenging situation, effectively utilizing natural resources to improve your situation.
