Sort of, but not really.
The speed of sound in water is 1480 m/s (at 20C), and is independent of the length of the vehicle.
Ships are sort of special because they operate at the surface of the water. Submarines operating submerged have no such "hull speed", and their wave-making resistance is insignificant.
