Okay kiddo, so have you ever heard of a race where people compete to be the fastest? Well, there's a special kind of race that happens on the ocean where huge ships try to cross from one side of the ocean to the other side as quickly as they can. This is called a transatlantic race.
Now, imagine all these big ships are lined up at the start line, and they all start racing to the finish line. The first ship to cross the finish line wins a special prize called the "Blue Riband". It's like a trophy but instead of being a cup or a plaque, it's a ribbon made of a special blue fabric that's given to the fastest ship in the race.
Winning the Blue Riband is a really big deal, and it means that your ship is the fastest and most efficient on the ocean. People have been racing for the Blue Riband for over a hundred years, and it's still considered one of the most prestigious awards a ship can win.
