wtf is this monstrosity

please make this automatic please

You don't really lose power across a gearbox. It is an oft-repeated myth. If anything you probably gain power, which I think is because of the non-conservative torque model in the game.

Having power loss on every single gear, this thing must be incredibly inefficient. Very likely having more loss on the gears than the loss you would have by accelerating a vehicle using wrong gears.

Finally a gearbox worthy for a fast and furious quater mile race.

Nope, you have to choose the gear yourself.

is it automatic?

Yes, but it's not really needed for ships.

does thus work for large ships

neat
