Final Answer:
The U.S. Coast Guard requires that all recreational boats have at least one wearable personal flotation device (PFD) for each person on board, and these PFDs must be Coast Guard-approved, in good condition, and of appropriate size for the intended wearer.
Step-by-step explanation:
Federal guidelines mandate specific requirements for personal flotation devices (PFDs) on recreational boats. According to the U.S. Coast Guard regulations, every recreational boat must be equipped with at least one wearable PFD for each person on board. These PFDs should be Coast Guard-approved, ensuring they meet the necessary safety standards. Additionally, the PFDs must be in good condition and appropriately sized for the intended wearer. The emphasis on wearability and proper sizing underscores the importance of ensuring that individuals on board have access to effective and reliable flotation devices in case of emergencies.
