Does anyone know the specific gravity of these battery packs?
Might make a difference on a ship.

“When commercial boat captains used to spot AMS’s vehicle in the waters, they often notified the Coast Guard, thinking that someone must have fallen off. Its fiberglass sail now says “unmanned vehicle” and includes a phone number for a passersby to call with concerns. Since making that change, Paintal said he’s received two calls. One was from the Boston Fire Department, and the other was from a pleasure boater. In both cases, their question was the same: What is this thing?”

Robo-Boats Are Setting Sail in Boston
A small industry of startups trying to teach boats to drive themselves is emerging along the harbor.

Hauling coal!  But other versions, to carry other cargo and passengers, are planned.

A new all-electric cargo ship with a massive 2.4 MWh battery pack launches in China
While it may seem counter-intuitive to launch an all-electric ship to carry coal, it’s actually a big step in the right direction. China moves a lot of coal and it’s better to move that coal in battery-powered ships than in ships burning incredibly polluting heavy fuels even if the battery-powered ships are powered by electricity generated by coal.

Some of the world’s largest cargo ships emit pollution comparable to millions of passenger cars put together. The heavy fuel oil that they burn has high sulfur content and therefore, it is an important part of the world’s transportation industry that needs to transition to being battery-powered.

It's even better to move batteries in battery-powered ships.  ;)

True, but progress almost always comes to us in small steps.
