Troubled Cook Strait ferry Aratere has been hit by more problems - cracks have been found in both rudders during its dry-docking in Singapore.
The ferry was on the verge of being returned to the water for sea trials this week with two new propeller shafts and refurbished stabilisers, after one propeller shaft snapped in Cook Strait on a routine sailing from Picton to Wellington on November 5.
InterIslander general manager Thomas Davis said the latest problem was revealed when the two rudders were being refitted.
"Ongoing checks identified a crack in the ship's port and starboard rudder stock - that is, the shafts which turn the rudders."
He did not say how long the unscheduled rudder repair work would take to fix but said the chartered Stena Alegra would continue on the Cook Strait run as the replacement charter ship for Aratere.
