Where should you look for breathable air when trapped under an inverted hull?

• A. Air Vent
• B. Air Pocket Near Top
• C. Air Bubble
• D. In the water

Answer: (B)

When a hull ends up inverted, any air trapped inside will rise to the highest interior point. Air is lighter than water, so it collects as a pocket at the top of the confined space under the hull. The breathable air you can access is that topmost air pocket, where the water level is lowest and you’re least likely to have water flooding the air you breathe. A vent on the hull isn’t a reliable source in this situation, and air bubbles are small and intermittent, making them unreliable for steady breathing. Breathing from the water is not possible, so the best place to look for breathable air is the pocket near the top of the trapped space.
