Interestingly though, there's a slow but steady push towards 24V on boats. More electronics are available in 24V version or simply support both 12V and 24V. And new boats tend to have a 12V and 24V bank. Electric sailboats usually have a 48V bank as well.

And in an entirely different area, 3D printing completed their transition from 12V to 24V some years ago, and currently there's an active push towards 48V.

I'm personally just looking forward to not spend a fortune on cables due to low voltages. It's frustratingly expensive to carry 12V a decent distance with some higher current draws.
