Photo: LDR / STUFFA passenger on the Interislander ferry, which lost its engines off Wellington's south coast, says they're back to full power. A captain announcement on-board the ship told passengers power has been restored, and anchors were coming up. The Interislander ferry, the Kaitaki, lost power and dropped its anchor south-west of Sinclair Head earlier this evening. Another passenger onboard said the swell was large for part of the sailing, but calmed down before the ship lost power. Wellington harbourmaster Grant Nalder confirmed the ship had dropped its anchor south-west of Sinclair Head on Wellington's South Coast.
