Would I realistically be able to have a propeller put together to propel a boat? Does BeamNG have proper hydrodynamics (like it has aerodynamics)?
Probably not, it was just a simple debug vehicle for the early stages of buoyancy. It doesn't work well any more due to all the adjustments.
I like new things even if they have a lot of bugs. Back when experimental was available, I used that all the time I played beamng.
Yup, in fact I'm working on a tugboat that uses two propellers for propulsion. Let me know if you need any help setting one up.
