USCG regulations do not require any B-II extinguishers on pleasure vessels up to 65 feet or 1,000 bhp, unless it is a passenger-carrying motor vessel.
However, where two or more B-I extinguishers are required, a B-II may be substituted for two B-Is, although it is a very bad idea to increase the risk that one extinguisher may malfunction and you would not have any backup.
Canadian regulations are somewhat different and require at least one B-II for any motor vessel over 8 meters or any other vessel that large, if there is a gas or liquid-fueled heating or cooking system aboard.

On federally controlled waters, boats less than 39.4 feet must carry specific safety equipment, including a personal flotation device (PFD) for each person on board, a sound-producing device (like a whistle or horn), and visual distress signals (such as flares). Additionally, vessels must have a fire extinguisher if they have an enclosed space. It's essential to also have navigation lights if operating at night or during periods of reduced visibility. Always check local regulations for any additional requirements.

If your vessel is less than 65.6 feet long and operating in federally controlled waters in Mississippi, you must carry a sound-producing device such as a whistle or a horn. This device is required to signal your presence in instances where visual communication may not be sufficient. Additionally, vessels must also comply with any specific regulations that may apply to the area of operation.
CO2 extinguisher have a max test pressure of 20,700 kPa. Max design operating pressure of 18,570 kPa. The min burst pressure of a cylinder must be at least 2.7 times the max operating pressure. So the burst pressure of a CO2 fire extinguisher will be at least 50,139 kPa
Aircraft are controlled in flight by the use of main control stick operating the ailerons and elevator, and the rudder pedals operating the rudder.
Four of the most critical components controlled by an operating system are: CPU, RAM, Hard Drive and Motherboard.
