The partnership was retained for the 2005 season. They took the C-2 500 m silver medal at the European championships in July but Woszczynski was then injured and unable to take part in the World Championships in Zagreb. It seemed as if Śliwiński would be left without a boat. However, when a member of Poland's four-man (C-4) 1000 m crew, Arkadiusz Tonski, also had to pull out injured, Śliwiński was called up as a last-minute replacement. The Polish four, ironically including the now rehabitated Gajownik, edged out the Romanian crew to take the gold medal. For the thirty-five-year-old Śliwiński it was the first C-4 gold of his long career.
