What pfds must be carried on a 18 foot powerboat?

On an 18-foot powerboat, at least one wearable personal flotation device (PFD) is required for each person on board. Additionally, a throwable PFD, such as a cushion or ring buoy, must also be carried. It's important to ensure that all PFDs are Coast Guard-approved and appropriate for the size and weight of the individuals who will be using them. Always check local regulations, as requirements may vary by state.
