I suppose the size of the > indentations might have a negative affect on this. The size is critical. It is also related to the velocity of the fluid along the surface. Golf balls have small dimples and move quite fast. SOF kayaks have relatively smooth changes over a large scale and move slowly in the water. I doubt that the shape changes in the SOF have a significant effect on the flow. BTW, aircraft floats operate by planing, not displacement (well, as you get anywhere near take off speed), so I doubt the analogy is completely correct.
