Naval trawler

A naval trawler is a special kind of boat that is used by the navy to help them do their job. It looks like a fishing boat, but it is much stronger and designed to be used in the water near coasts or in rivers.

Just like a fishing boat, a naval trawler has a big net that it drags behind it in the water. But instead of catching fish, the net is used to search for things like mines, which are dangerous explosives that can float in the water and hurt ships. The trawler pulls the net along slowly to make sure it doesn't miss anything important.

Sometimes, naval trawlers are also used to patrol the water and watch out for any suspicious activity. They can be equipped with special technology that helps the navy see things like submarines or other boats that are trying to hide.

Naval trawlers are important because they help keep the navy and the people who use the water safe. Think of them like the navy's special fishing boats, but instead of catching fish, they catch dangerous things that might hurt people or ships.
