There’s like a 90% chance you’re right, but aerodynamics gets especially messy with stuff like this that has a more or less flat wall at the back. A significant portion of the drag comes from the turbulence behind the vehicle, rather than cutting (more “plowing” in this case) through the air in front. When you change the geometry of the back, you change that drag.
So, if I were to bet, I would bet that turning the boat around would help. But I wouldn’t bet my life on it. Some wacky interaction with the geometry of the rear could somehow cause it to get worse.
Okay but there’s no way the flow separates from that roof enough to clear the boat
I would guess the same, but for a wacky shape like that rv it’s pretty hard to say
Okay but if they would just at the very least, turn that boat around 180°, I’m pretty sure the aerodynamics would improve.

You’re going to make me learn OpenFOAM aren’t you
Do it! It’s great fun to play around with!
Ive worked with Ansys Fluent in university but really fucking love CFD and could probably use the practice regardless.
Ah…right…old laptop and AI-driven component shortages… Someday I’ll have a shitload of compute, just you all wait!
