Dry power may be difficult to clean up, may be corrosive on metal surfaces, including electronics, and can create a large cloud that settles well beyond the fire. Cost may also be a factor, compared to recharge or replacement of other types.
Multi-purpose fire extinguishers, like ABC, are typically dry chemical.
D and K fire
FIRE extinguishers are used to put out fire.

It suffoctaes the fire by depriving the fire of air which it needs to burn.
They form a barrier on the surface of the burning substance - which melts to form an airtight layer - starving the fire of oxygen. Smother the fire
Nitrogen can be used in fire extinguishers as gas propellant.
Some fire extinguishers use dry chemicals and some use a foam to extinguish flames. Some fire extinguishers actually still use water, but they're only for use on smaller fires. Others use a dry chemical, mostly sodium bicarbonate, or Carbon Dioxide.
No, there are boats that do not need any fire extinguishers.

Fire extinguishers are best used on incipient (at the beginning) fires.
The white stuff in fire extinguishers is typically a chemical called dry chemical powder or monoammonium phosphate. This powder is a fire suppression agent that is effective for extinguishing different types of fires, such as those involving flammable liquids, gases, and electrical equipment. When released, the powder smothers the fire and helps to cool the fuel, preventing it from reigniting.
