In addition to the required wearable PFDs (life jackets) what other equipment must be on board if your vessel is 16 feet or longer?

In addition to the required wearable personal flotation devices (PFDs), a vessel that is 16 feet or longer must also carry a throwable flotation device, such as a ring buoy or cushion. Additionally, it must be equipped with a fire extinguisher, a sound-producing device (like a whistle or horn), and navigation lights if operating after dark. Depending on the specific waters and regulations, other equipment such as a first aid kit or visual distress signals may also be required. Always check local regulations for any additional requirements.
