When a boat less than 26 feet in underway what properly sized PFDs must be worn by children in Florida?

In Florida, when a boat measuring less than 26 feet is underway, children under the age of six must wear a properly sized and Coast Guard-approved personal flotation device (PFD) at all times. For children aged six and older, PFDs are not required to be worn while on board, but they must be available on the vessel. It's essential that the PFD fits the child correctly and is suitable for their weight and size.
