Why is the boat used in the afternoon race so different from the ordinary wooden boat?

The two main differences are: the dragon head, the dragon tail and the hull decorated with scales, the totem of the Chinese nation, needless to say, otherwise it is not called the dragon boat race; The difference between the two lies in the function. In addition to speed, ordinary wooden boats should also consider the function of carrying goods. Wider boats are less prone to rollover, so they are more stable, while dragon boats are mainly competitions, so they are longer and narrower in design than ordinary wooden boats.
