Final answer:
If your boat capsizes and remains floating upside down, the best course of action is to swim away from the boat and remove your PFD. This ensures your safety and allows you to seek help if needed.
Step-by-step explanation:
If your boat capsizes but remains floating upside down, the correct action to take is to swim away from the boat and remove your Personal Flotation Device (PFD). Staying close to the overturned boat can be dangerous as it may trap you underneath or push you against rocks or other hazards. By swimming away, you are moving to a safer location and can call for help or signal for assistance.
Swimming up under the boat to stay out of the wind is not recommended, as it exposes you to potential dangers and hinders your ability to seek help. Pushing the boat until it floats away is also not a recommended course of action, as it won't guarantee your safety and may lead to exhaustion.
Remember to prioritize your personal safety and make decisions that will increase your chances of being rescued or finding help.
