A hopper barge comprises two longitudinal buoyancy chambers hinged together beneath the deck and defining over a part of their lengths a passageway interposed therebetween, which chambers can be adjusted relative to each other by means of at least one hydraulic cylinder located above the deck and hingedly connected thereto. According to the invention, the or each hydraulic cylinder has both the hinged connection of the piston rod and the hinged connection of the cylinder to the associated barge section spaced the same distance from the vertical longitudinal center plane of the barge and located near the middle of the piston rod and the middle of the cylinder, respectively.
