It happens sometimes that the merchant is required to change the destination of a consignment after the bill of lading has been prepared and the ship is on the high seas. Often this is so because a customer decides that the goods are needed at a different location, perhaps another of several processing plants, to the one agreed at the time of placing the order. Alternatively, goods may be sold while on the high seas to an end user in a different location to the original customer. Such a change of plans would only be viable if the new destination is one of the ports on the vessel’s itinerary at which she has not yet arrived or a place inland from one of the ports on the vessel’s itinerary at which she has not yet arrived. From the ship’s point of view, there are two factors involved in a change of destination: flexibility and cost.
