The trawler towed a very large net through the water behind it, catching hundreds of fish from the sea floor.

That man is the captain of a trawler, and his ship brings in dozens of fish that they catch in their nets every day.

It is very interesting to work as a crewman on a trawler, as the net often brings up a lot of interesting things that aren’t fish.

This trawler must have a very powerful engine, so that it can pull the large net through the water behind it to capture its bounty.

Any ship can be considered a trawler as long as it tows a net behind it to capture fish from the sea floor.
