What is required equipment for personal watercraft?

In Florida you are required to carry at least (1) B-1 fire extinguisher, a day emergency signal device, i.e. distress flag, whistle, USCG approved day signaling device (since Jet Ski's are only supposed to be operated during the day, operating at night is illegal), but incase you get stranded at in the dark a night signaling device i.e. flashlight, flare (if desired, not required) and enough PFDs (life jackets) for every passenger.
