When capsized and floating on your back in a swift river current how should you position?

When capsized and floating on your back in a swift river current, you should position your body with your feet slightly elevated and pointing downstream, allowing them to absorb impact from any obstacles. Keep your arms out to the sides for balance and avoid tensing up; instead, stay relaxed to help with buoyancy. Aim to look upstream to assess your surroundings and identify any hazards. If you need to steer, use gentle movements with your arms and legs to guide your direction.
