Okay, so do you remember when we learned about submarines? They're like big boats that can go underwater and explore the ocean. Well, personal submersibles are like really cool, fancy submarines that people can buy and use for their own adventures.
Now, sometimes people who have personal submersibles like to get together and go on trips together. Kind of like when you and your friends go on a playdate or field trip. But when a lot of people with personal submersibles want to go on a trip together, they need to organize it. That means they need to plan where they will go, what they will do, and how they will stay safe.
So, a personal submersibles organization is a group of people who own these special submarines and want to go on trips together. They work together to plan and organize these trips so that everyone stays safe and has fun. Think of it like a big group of friends who all want to explore the ocean together, but they need to plan it all out first so that they don't forget anything important.
Does that make sense?
