May I add a little bit to that, to the hydrographic charts? As you said, only about 20% of the Arctic waters are charted. It's really difficult for the cruise ships to enter certain areas, especially when the waters are not charted. Even though there's a huge cliff here and another one there and it must be thousands of feet deep in there, they can't enter that harbour because it's uncharted. It's a risk.
There are very scenic and very nice areas they cannot go to. They have to follow pretty much a straight path, because the waters are not charted.
