At the speed of sound over water, you would have to be riding an air cushion since the friction of water contact would be too great. That said, any small wavelet that touched the craft could cause a disaster. . Underwater the speed of sound is higher than the speed of sound in the air, but either speed would be unattainable due to the friction of passing through the water.
