A lower lamella has a first point secured to the front end of the main skirt below the upper lamella, a second point secured to the rear end of the main skirt below the upper lamella and a third point provided at a distance from the main skirt. A front towing interface is connected to the third point of the upper lamella and the third point of the lower lamella. The floating body, the main skirt, the upper lamella and the lower lamella are made of one or more flexible materials. The upper lamella has a skirt facing edge defined as the edge between the first point and the second point. The skirt facing edge is secured continuously or at intervals to the main skirt. The paravane includes at least one intermediate lamella having a first point secured to the front end of the main skirt between the upper lamella and the lower lamella, a second point secured to the rear end of the main skirt between the upper lamella and the lower lamella and a third point provided at a distance from the main skirt. The third point is connected to the front towing interface. The paravane includes a plurality of stiffening plates fastened to the main skirt.
