All I know about the MANZ run was when I signed on the Port Macquarie for a round trip to NZ like everyone else did espescially as about four on deck where on their last trip before swallowing the anchor. As soon as we let go they hoisted the Maple Leaf flag and that was the first we knew that we where on a MANZ run so Port Line where not always up front with their crews as to the intent of the voyage. As for articles being for two years. We had a few bebates about this and the result which might not be correct but one we accepted as fact was this. The company had to pay you of after two years under articles unless the ship was heading to a UK port so if your two years where up say in OZ and you hit every port between there and say London then you could be on that ship for well over two years. That was just mess room talk but could see the companies using something like that to suit their needs.
That's the way the mop flops.
