Yes, this is a different effect as I recall unrelated to the Reynolds number. The idea was something like trapping a layer water molecules right against the skin would have less drag than an actual smooth surface. This micro textures is on a scale a lot smaller than is used to increase the Rn number on the surface. This would be of benefit to a kayak hull, assuming you can reproduce it acurately, and maintain it clean and undamaged.
