CHAPTER 1 Dragon Boats Dragon boat races began in China over 2,000 years ago. Now more than 50 million people all over the world race the boats.

There are 20 to 40 racers in each dragon boat. When the race begins, a drummer on each boat makes a beat. The drum helps the racers paddle together. They paddle 60 to 85 times every minute. beat: a sound that repeats
Why are dragon boats fast? Dragon boats are not heavy. They are light in weight. This makes them go fast. Dragon boats have low sides. Boats with low sides float high in the water. This also makes them go fast. It takes less work to move a dragon boat. DRAGON PARADE The city of Boston, in Massachusetts, has a Hong Kong Dragon Boat Festival every year. People march, or walk, in the parade with dragons. Racers must work together to win a race. Racers push paddles in the water to make the boat's speed fast or slow. If paddles are too big or too small, they are hard to move in the water. It is harder to move a large paddle through the water. A smaller paddle is easier to move. It can move faster through the water. push: to move forward

The ice boat racer stops the boat by moving the front of the boat into the wind. Ice boats are powered by the wind. Ice boat racers turn the sails to get wind inside them. Then the wind pushes the boat. Ice boaters can use the wind to turn, or steer, the boat. When the wind moves a different way, the ice boat racer turns the sails the same way.
