Sonic boom in water?
I have been wondering if a displacement hull that moves fast enough
would create a sort of "sonic boom" just as an object moving fast enough in air does. In air, the shock is created when the aircraft moves too fast for the air to get out of the way. In water, a displacement hull attempts to climb its bow wave which effectively limits its speed. Apparently, this hull speed is not a mathematical limit but merely a practical limit as sufficient power can move a hull over hull speed. However the power necessary to produce any further increase in speed radically increases above hull speed. If you did manage to produce enough power, could you power through the bow wave and thus produce a shock wave? |

"If you did manage to produce enough power, could you power through the
bow wave and thus produce a shock wave?" If you did, you would be on plane, traveling over the water for the most part, and leaving any remnant of a bow wave behind the boat. Any relation of this phenomena to a sonic or acoustical shock wave is only academic, since the speed of sound in water is about 5 times faster than air, so it isn't likely that there will ever be a watercraft moving at 3500mph. |

I believe Skipper claimed his Bayliner came close to that speed at WOT once while on the Sea of Cortez trying to outrun a giant Tostito. ;-) |

Yes........in 55 gallon drums strapped onto the deck. |

My impression is that a planing hull has no relation to hull speed.
Furthermore, we are not talking about the speed of compressional waves as in sound but the much slower surface waves. |
