The 19000hp tug Janus has sailed for Halifax to collect the Australian Spirit. She will then tow the Australian spirit to Portugal to be fitted with a new rudder. According to marine traffic the tug is due on the 6th.
It have heard that when the Australian Spirit was Inspected, it was found that the rudder shaft had broken and the rudder had fallen off. it was suggested that the rudder post may have been bent however the lower rudder gudgedon had marine growth where the bearing would have been, suggesting the whole thing was damaged in the past.
