Is it better to use chemical flares or smoke signals for rescue?

Types of Signals

Chemical flares are the preferred choice for maritime rescue signaling due to their high visibility and long-range capabilities. They can be seen from a distance of up to 30 nautical miles (55 kilometers) and are effective during both day and night. Smoke signals, on the other hand, are more effective during the day but can only be seen from a distance of up to 10 nautical miles (18 kilometers).

Signal Duration and Rationing

When using chemical flares, it’s essential to ration them carefully to ensure you have enough for the entire rescue signaling period. A typical life raft has a limited supply of flares, usually 2-4, and these should be used to signal for help during peak hours, typically between 10 am and 4 pm when rescue aircraft are most active. To optimize flare usage, signal for help in short bursts, such as 1-2 minutes, followed by 2-3 minutes of rest to avoid overheating and conserve energy.

Fishing and Signaling

While fishing can be an essential survival skill, it’s crucial to balance fishing with signaling for help. Set aside specific times for fishing and reserve your energy for signaling. Use your fishing skills to catch fish and store them in a safe location, such as a cooler or a designated area, to conserve energy and stay hydrated while signaling for help. Remember to prioritize signaling and use your flares and other signaling devices to attract the attention of potential rescuers.
