Safe water mark

A safe water mark is a special sign that helps big boats and ships know where it's safe to go in the water. It's like a big arrow that says "this way is safe"! These signs are usually found in places where the water can be very shallow, or where there are rocks or other obstacles that could hurt the boat.

Boats and ships are very big and heavy, so they need lots of water to float safely. If they go into shallow water or hit rocks, they could get damaged or even sink! A safe water mark is like a big sign that helps the boat captain know where to go to avoid all these problems.

Usually, these marks have a bright color, like red or green, so they are easy to see from far away. They might also have lights or reflectors to make them even more visible at night. So when the boat sees these signs, they know that they are in a safe area, and they can keep sailing without worrying about anything bad happening.
