Abstract
The results of the experiments with the beach seine model are described. Two experiments have been made. During the experiment the tension of the wings and hydrodynamic force of drag have been measured with the strain-gauge transducer. According to the results of the experiments graphs demonstrating the dependence of the forces on the model shape, have been made. The model shape is described by the ratio of bending deflection to the distance between the wings of the beach seine. In the first experiment, the parameters were changing with the movement of the both wings, in the second experiment one wing was fixed at one point and the shape was changing with the movement of the other wing. With the growth of this ratio the tension of the wings and the hydrodynamic force of drag of the model were declining.
