Okay kiddo, let me tell you about the Royal National Lifeboat Institution, which is also called the RNLI. It's a group of people who work together to rescue people who are in trouble in the water, like in the ocean or a big lake.
The RNLI has lots of special boats that are called lifeboats. These lifeboats are different from regular boats because they are made to rescue people in dangerous situations. They can go out in really bad weather and big waves to help people who are in trouble.
The people who work for the RNLI are really brave and strong. They are called lifeboat crews and they're made up of volunteers and some people who get paid to do this job. They have special training so they can help people safely and quickly.
But the RNLI does more than just rescue people in the water. They also teach people how to stay safe while they're enjoying the water. They go to schools and talk to kids about water safety, and they even have special programs for people who like to go boating or swimming.
And here's another interesting fact, the RNLI has been around for a really long time. They started in 1824, which is way before you or I were born. They've been helping people for over 200 years!
So, in summary, the Royal National Lifeboat Institution is a group of really brave people who work together to rescue others in trouble in the water. They have special boats called lifeboats and they also teach people how to stay safe around the water.
