For short haul (think ferries) the same calculations will make electric ships feasible when distance travelled is 1 or 2 order of magnitude less. Such ships already exist.

Yep, that is feasible today. Coastal ferries and routes counted in hours.

Here's a larger ferry connecting Sweden and Denmark that was converted to hybrid with the goal to not use any diesels in regular service. Has 4 160 kWh battery capacity, one trip takes 20 minutes and uses 1 175 kWh.
