An item reported that on the sectionsingle Kozle-Wroclaw-Redzin [the former German places Cosel-Breslau-Ransern] the Polish screw steam tug Bozymir master Pietr Ptok was active. Dutch built. Horsepower 250hp.(1)
A new river convoy was formed with below the last sluice near Redzonthe small tug Podhalanin especially used there for the local formation. Some barges were from there towed to their destination, others went on own power when the cargo was to be delivered according to a time schedule. If so such a barge needed minimal 8 days to go from Redzin to Szczecin, when towed maximum 5 days. The travel time for this section was just 48 hours. Were all the locks in full operation, the entrance to the sluice in Katy near Opole, the lock entrance at Groszowice [Groschowitz] and the point blow the bridge in Olava (alluvial sand deposits) were still potential problem areas.
