Lots of examples! To pick a few:
- Manhattan to the Hamptons
- Los Angeles to San Diego or Santa Barbara
- Interisland in Hawaii, New Zealand, Japan, Caribbean, Pacific Northwest
- The global ferry market, huge in places like the Mediterranean, North Sea, Baltic Sea, English Channel, Southeast Asia. Actually, there are as many ferry passengers every year as there are airline passengers! ~4.5B on both... its a key mode of global travel
As battery tech evolves to enable ranges of up to 500 miles, we can add routes like Los Angeles <> San Francisco and Boston <> New York. I'm excited about those.
Keep in mind that in some cases ferry travel only makes sense because the ferry can also carry passenger vehicles/trucks with freight. But like an airplane this new vehicle is passenger only.
I was thinking this was impractical (the Cape is in the way) but Nantucket is pretty far East so it's not that bad to go around. ~115mi each way, so within range.
