The experience of the training ship State of Maine following Katrina reported here:
Our experience shows that you can do disaster relief in the perimeter and in the river systems of the United States via the water. It’s a very good way to do it. It worked well in New Orleans with road and rail infrastructure that was not damaged. And then you think about what could happen in San Francisco or Los Angeles area with an earthquake. Out there, the infrastructure of roads and railroads would be destroyed, so the only way you could help people would be by water.See earlier post on the topic of disaster logistics from the sea here.
