I went on their last one. Not bad, but we didn't actually make it over to the container port, so I just might go again. Kill van Kull is always great for ships and tugs.
Also, the majority of the crowd were non-photography types "of a certain age" who wanted to sit inside and look out the windows of the upper deck. They got in a huff when we were lined up, standing at the rails and blocking their view.
