Fireboat

A fireboat is a special kind of boat that helps firefighters put out fires that are very close to water, like fires on boats or buildings by the water. Fireboats are big and strong with powerful pumps that can shoot water many feet into the air to put out the fire. They can fill up their tanks with water from the ocean or river and spray it on the fire to make sure it doesn't spread. Just like a firefighter’s hose, the water that comes out of a fireboat’s hose is very strong and can knock down flames and keep everyone safe. So, it's like a superhero boat that fights fires on water.
