Yes I see what you mean. I should not have tried to be polite and say “more or less”.
In the rest of your post you confirm that they are actually non-existent.
Otherwise an informative post. I’ve seen the feeder ships at work in Europe. They could be extremely beneficial to us here. We do have some container barges working, and some ATBs designed (but not built) for the work, but ships might be a stretch due to the manning requirements.
