To solve the problem that dragon boat athletes cannot train on land, a training device for double dragon boat is proposed, which consists of a safety balance frame, a boat body, a paddle training device and a simulated water surface device. The trainer uses the wind wheel rotation to provide resistance, simulates the motion posture of the double dragon boat rowers in the water, and guides the boat through its own path with the guide rails to realize the function of the height change and left-right swinging of the dragon boat in the water, so as to meet the training requirements of the athletes on land.
