Plotting three variable (trajectory with angle) in a single plot as function of one another with help of line

Hello, I am having a plot of turning circle made by a ship model. I have the displacement of ship's center of gravity in x and y direction as function of time and also the angle of ships heading as function of time. These are shown in figure below.

plot(x); plot(y); plot(psi);

I am able to plot trajectory of my CG of my model in x-y plane as shown in second figure.

plot(x,y)

I want to add information of the angle that ship is making while taking turn with help of small pointed arrows representing the heading. How can I do it? I have made a demo figure of what I want.
