Article quotes `40 megawatt-hours of installed capacity.` - Surely this can get you pretty far from Tasmania to South America.

apparently, 40MWh of capacity is enough to travel 40 nautical miles. The distance between Tasmania and South America is around 6,500–7,500 nautical miles.

For comparison, a wide body airliner needs ~0.15MWh to travel 1 nautical mile.

I would be extremely surprised if the ship were designed to use 100% of its capacity in one way of its intended route.

The drag on a vessel is orders of magnitude larger than the drag on a car.
