Until you realize that the energy requirement is also different. Land transport in general is very inefficient. Ship is in fact one of the most energy efficient means of transport.

I don’t disagree but every time I’ve seen a diesel engine on a cargo ship it was absolutely massive.

194 nautical miles isn’t terribly far, though. For port to port, sure. For oceanic shipping, I don’t think 194 is going to cut it. I think we will probably have to do SMRs or efuels to really cut cargo ship and cruise ship emissions when crossing the Pacific or Atlantic. Though I don’t know where nuclear powered shipping (in non-military applications) is in terms of progress.
