Unless there was oil in the water... that sure doesn't look like 5 knots...
Man, let me put it this way.
If I see such a water surface in a light wind race then I'm running for it. These are wavelets created by the turbulent nature of the windlayer above => ergo there is 5 knots of wind or more above that surface. Winds of less than 5 knots are laminair in nature and will leave the water surface glassy and flat, as in those spots we see on those light wind days ? The start line in the pictures is certainly NOT such a spot.
