Floating dock (jetty)

A floating dock or jetty is like a big mat that floats on the water. It's like a big raft that you can walk on and it's mainly used for boats to tie up to. The dock is made up of lots of little plastic pieces that are put together like a puzzle to make a big flat surface.

The dock is held in place by some big pipes or cables that are attached to the bottom of the water. Sometimes the dock can move around a little bit because the waves in the water move it, but it's still safe to walk on because it's designed to float.

The great thing about a floating dock or jetty is that it can move up and down with the water level. So, even if the water goes up really high or down really low, the dock will still stay at the same height. That's really important for boats because they need to be able to easily get in and out of the water no matter what the water level is.

Overall, a floating dock is like a special type of mat that can stay flat and level in water and is used for boats to tie up to.
