When is each person on board a motorboat required to wear an approvment PFD?

In general, each person on board a motorboat is required to wear an approved personal flotation device (PFD) when the vessel is under way, especially when it is less than 16 feet in length or when navigating in specific hazardous conditions, such as during rough weather or near the shoreline. Additionally, regulations can vary by state or region, so it's important to check local laws for specific requirements regarding PFD usage. Children under a certain age often have stricter rules, typically requiring them to wear PFDs at all times while on the water.
