From your perspective, the waves generated by a boat behind you will appear to move forward.
When a boat moves through the water, it creates waves that radiate outward from the boat's location. These waves propagate away from the boat in a radial pattern. As the boat moves forward, the waves move away from the boat in all directions, including towards the area where you are located.
When you are facing forward, the waves generated by the boat behind you will catch up with you and pass by. From your perspective, you will see the waves moving in the same direction as you, which is forward. This is because the waves are traveling towards you from the boat behind, even though the boat itself is moving in the opposite direction.
So, to summarize, the waves from a boat behind you will appear to move forward as they propagate towards your position.
