The working peniche Cabourg, traveling empty on the river Oise. These barges were built to completely fill a standard French Freycinet-scale lock, at 38.5 meters long by 5.1 meters wide. The bow and stern are both blunt and broad-shouldered, so as not to waste any volume available in the locks. These vessels are built to do a specific job and are only for use on inland waterways, so it is not necessary for the bow to split waves, or for the shape to look aesthetically pleasing.
