What must be visable on a personal water craft?

A personal watercraft (PWC) must display a valid registration number, which is usually affixed to the hull, and it should also have the registration decals visible. Additionally, it is important for the operator to have a wearable personal flotation device (PFD) for each person on board. A fire extinguisher may also be required, depending on local regulations. Always check specific state or local laws for any additional visibility or safety requirements.
