Yeah, I’m not super concerned about realistic physics either. Most existing boat tutorials (and there are not many) factor in waves, etc, which isn’t super necessary for me (at least not initially). It was mainly the drag forces that I was curious about, and how if affects turning/movement.
Would you consider releasing the code or doing a specific guide to the boat physics? Boat physics are something I have recently been interested in, but struggle to find a good implementation.
