I am still puzzled though. I still don't understand how you could have a situation where something is grave and imminent and you wouldn't take this measure. Grave and imminent may be, for instance, if there's an oil spill. Okay, there's a particular type of response you do to that. You put booms around and you try to clean it up. This seems to refer more to a navigation hazard. That's the impression I get. If somebody says that's a grave and imminent danger to navigation, they wouldn't say that if the vessel were isolated and there are not other ships around, you wouldn't think. You wouldn't find it grave and imminent. There does seem to be a bit of a disconnect here.
