What equipment is required on all boats per regulations?

The correct answer includes fire extinguishers and life jackets because these are fundamental safety devices mandated by boating safety regulations. Life jackets are essential for ensuring the safety of all individuals on board, providing flotation in case of an emergency. Fire extinguishers are critical for addressing potential fire hazards on the boat, particularly in the engine compartment or galley, where flammable materials may exist.

Regulations require that boats, depending on their size and type, must carry a minimum number of life jackets for each person on board as well as fire extinguishers that meet specific criteria. This ensures that the vessel is prepared to respond to emergencies, enhancing the overall safety and preparedness while on the water.

Other equipment mentioned, like GPS and sonar devices, while useful for navigation and fishing, are not universally required by law for all boats, which is why they do not fulfill the criteria for this specific question. Navigational charts, although important for safe navigation, are also not universally mandated on all boats.
