<p>The device comprises at least one pair of flexible ballasts (3) which extend laterally along the length of the inflatable structure (1) and each comprise an orifice (6), acting as a vent, situated at the front, and a scoop system (4) situated at the rear with, between these ballasts, at least one pipe (5) which connects the cavities of said ballasts (3) to equalize their level of fill and the stagnation pressure of the water obtaining in said cavities when the inflatable structure is pulled along in the inflated state. This scoop system (4) either consists of a component moulded in a rigid or semirigid thermoplastic or is made of an assembly of cutouts from a flexible material of the watertight fabric type, and this scoop system is bonded and/or welded to the ballast (3).</p> |
