| Globally, annually, there is roughly 850 million twenty-foot equivalent units (TEU) worth of containerized goods handled at ports worldwide. Aside from container shipping there is raw bulk material shipping, eg: Western Australia ships > 800 million tonnes of raw ores to China annually (not local, not light). Looking at just container shipping and the major major routes; there is * 42 million TEU's intra asia (within asia, 'local' but not necc. 'short') * 42 million TEU's 'far east' to Europe + North America. and then a long tail of lesser volume routes, many quite lengthy (asia -> south americas, north | south americas, etc.) Point being by "vast majority" are you talking raw ship numbers (there are many small ships) or cargo volumes | weights? There is a truly vast amount of heavy tonnages being moved long distances and these consume the majority of shipping energy. If this is your line of argument then it deserves some refining to move past a handwave. |
People underestimate how many routes can be done with battery powered ships.

My argument was not limited to that. I also said there are other solution that are not direct usage of hydrogen.
