It was a scary crossing of Cook Strait for 800 passengers on the Kaitaki Interislander ferry on Saturday.
The boat lost power amind three-metre swells and high winds and drifted nearly a mile off course.
The Transport Accident Investigation Commission has launched an inquiry.
And a question now is: what impact will there be on ferry bookings, particularly as we are in the final days of the school holidays.
KiwiRail's executive general manager for the Interislander Walter Rushbrook spoke to Corin Dann.
