To give an autistic answer:
The speed of sound in water is around 1500 m/s, as compared to the around 340 m/s in air.
Also water is about 800 times denser than air.
So unless you can fly 5 times faster than normal in a medium that is hundreds of times denser and thus gives far more drag to slow you down, no, you can’t pull off a sonic rainboom underwater.
