It depends on the make and model. It's safe on most PWCs so long as the car is not running at the time.
In Florida, those born after Jan. 1, 1988 operating a vessel powered by a motor of 10 horsepower or greater (including PWCs) must have a Florida Boating Safety Education ID card. In Georgia, any person 12-16 is required to have a Georgia Boater Education Card (also referred to as the GA Boating License) if they are operating without direct adult supervision.

All of them. Plus PWCs can only operate in daylight (sunrise-30, and sunset +30), operator and passengers must wear floatation vests at all times, and towing of skiers, or towable devices is prohibited in most states.
The most common hull material is fiberglass, often with an epoxy resin outer coating. The most common hull design is a modified-V, sharper at the bow and progressively softer as you move further aft. Many PWCs have sponsons, fin-like structures at the rear on both sides. They act like rudders, improving handling in tight turns, and they also act like floats, improving stability.

PWCs and boats up to 26 feet must carry at least one B-I fire extinguisher unless exempt (i.e., Class A or 1, open, outboard motor, not carrying passengers for hire, etc). A B-1 extinguisher may be a 2-pound dry chem, 4-pound CO2 or 6 quart foam, if properly labelled as USCG certified. Boats 26 to 40 feet must carry two B-I or one B-II. If there is a permanently installed fire extinguisher system only one B-I extinguisher is required. For vessels 40 to 65 feet, three B-I or one B-II and one B-I extinguishers are required. Vessels in this class with permanently installed fire extinguisher systems are required to carry two B-I or one B-II extinguishers. Vessels without combustible fuel onboard, no gasoline engine or no areas where vapors can be trapped are not required to carry a fire extinguisher.
