A dive boat is like a bus that takes people who want to go underwater on an adventure. It has a big flat area on the back for people to get ready and put on their diving gear. The captain drives the boat to a cool spot in the water where there are lots of fish, reefs, or other things to see. Then, the people who want to dive put on all of their special equipment like masks, fins, air tanks, and weight belts. They jump off the boat into the water and swim around looking at all the cool stuff underwater. When they are finished, they swim back to the boat and climb aboard. The boat then takes them safely back to the shore.
