An emergency wreck buoy is a big floaty thing that is put in the water to help rescue people when there is a shipwreck or some other kind of emergency. It is usually bright in color like yellow or orange so that it can be easily seen from far away.
This buoy has a lot of cool features that can help rescue teams find and save people in danger. For example, it has a GPS device that can track its location and show rescuers where it is. It also has flashing lights that can be seen at night so that rescuers can find it even when it's dark outside.
Another really important thing about the emergency wreck buoy is that it alerts rescue teams when it is activated. When it senses that there is an emergency, it sends out a message to a special station on land that tells them where it is and that someone needs help.
Overall, an emergency wreck buoy is like having a superhero in the water that can help save people in danger. Its special features make it an important part of any emergency plan and can help make sure that everyone is rescued quickly and safely.
