How do I describe the path of a boat with a curve?

Hello math wizards of the forum. I have a question regarding a somewhat special bezier curve. I am trying to describe the path of a turning ship with a bezier curve like in the game

I also tried the navemesh agent but it can move very unlike a boat. Anyone have an idea or a hint where to start to create a curve that describes the movement of a boat and takes its turning radius into consideration?

How did you get an idea that a bezier curve describes a path of a physical object, with momentum and stuff? That can easily give you very unrealistic paths.
I checked the video. From what I see, there’s simply a circular path followed by a straight path. So try to define a turning radius of your boat, calculate the angular distance of how much you have to travel on that circle before you can move straight.
