The difference between fast paddle and slow paddle in dragon boat.

The difference between the fast paddle and the slow paddle of the dragon boat is as follows:

1. Blade shape: The blade shape of the fast paddle is flatter than that of the slow paddle, and the paddle surface is more inclined, so that the fast paddle can cross the water surface faster when paddling, and the water resistance is reduced. The blade profile of the slow propeller is relatively thick and the blade surface is relatively flat, which is suitable for low-speed use and can provide greater thrust.

2. Paddle area: The paddle area of the fast paddle is relatively small, which is suitable for high-speed use and can provide faster paddle speed; However, the blade area of the slow propeller is relatively large, which is suitable for low-speed use and can provide greater thrust.

3. Paddle handle length: the paddle handle length of fast paddles is relatively short, which is suitable for high-speed use and can provide faster rowing speed; The handle length of the slow propeller is relatively long, which is suitable for low-speed use and can provide greater thrust.

4. Manufacturing materials: the manufacturing materials of fast paddles are generally light carbon fiber, glass fiber and other materials to reduce the self-weight of paddles and improve the rowing speed; However, the material of slow propeller is relatively heavy, and the commonly used materials are wood and aluminum alloy. To provide greater thrust.
