On a fine, calm day ‘Cruising on The Interislander’ can be like a luxury Mediterranean cruise, but Cook Strait can be one of the world's roughest stretches of
water. Often, the ferry experience is less The Love Boat and more the 'chuck bucket'.
Crossing Cook Strait is often idyllic, but it can be one of the world’s roughest stretches of water as it's part of the westerly wind belt known as the Roaring Forties.
Cook Strait ferries were vital to the flow of freight and
passengers between the North and South islands, and interruptions because of bad weather, mechanical problems or strikes and lockouts inevitably
hit the headlines.
