You're speaking theoretical physics, in an ideal world... however, in the real world, the wind speed at deck level isn't the same as the wind speed at the higher levels... and it could very well have a deck-level wind speed of zero, yet still have enough wind to move the boat at deck-level wind speed.
Stop using the rose-colored glasses and look at the real world.
I'm not saying the boat is going as fast as the wind at mast top level, or even 20' up... just that at the deck it is possible for the boat to be travelling at the same speed as the wind at DECK LEVEL.
The energy for making the water gurgle is coming from the wind higher up—not the wind at DECK LEVEL. You seem to want to treat the entire boat and wind as a single thing... it's not. The wind speed varies with height.
I've been using cassette tape tell tales, and they're generally light enough to at least indicate if we've got any apparent wind...AT DECK LEVEL. There are plenty of times when we've been sailing DDW or close to it, and there's been nothing at DECK LEVEL.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
