Water safety

The 120 rule + kayak/SUP checklist

Conditions & checklist

The 120 rule: if air°F + water°F < 120 — a wetsuit is needed. Cold water doesn't kill instantly: cold shock in the first 60 seconds (involuntary gasp reflex), then loss of muscle control in ~10 min, hypothermia in ~30. Stay with the craft — it sinks less often than a swimmer tires.
