WebWaves generated by a ship are affected by her geometry and speed, and most of the energy given by the ship for making waves is transferred to water through the bow and stern parts. Simply speaking, these two wave systems, i.e., bow and stern waves, interact with each other, and the resulting waves are responsible for the resistance.

As the ship advances, it creates a pressure wave at its bow – a bit like having a strong tail wind while you’re on a bicycle. While in that wave, dolphins have little more to do than just navigate to ensure they’re going in the right direction.
