You should swim to shore during a self-rescue when it is the safest and most efficient path to safety. Key factors to consider before swimming include:
- The distance to shore: Swimming to shore is advisable if the shore is close (e.g., a few hundred feet), but swimming long distances (like a mile or more) can lead to exhaustion and danger.
- Water conditions: Calm water is easier and safer to swim in, while rough water, big waves, or strong currents make swimming difficult and hazardous.
- Your physical condition: You should feel strong and capable; if injured or tired, it is safer to conserve energy by floating or treading water.
- Presence of immediate danger on your current location (e.g., fire, sinking, or explosion on a boat) which would necessitate swimming to shore quickly.
- Hazards near the shore: Avoid landing on dangerous rocky or cliffy shores; look for a safe landing spot.
If conditions are unfavorable (long distance, rough water, hypothermia risk or exhaustion), do not rush to swim to shore. Instead, stay afloat, conserve energy, signal for help, and wait or look for closer safer alternatives. In summary, swim to shore as a last resort when it is safe, the shore is reasonably close, and you have enough strength and favorable water conditions. Otherwise, prioritize staying calm, conserving energy, and signaling for help.
