You would be surprised by what some sailors can achieve. I remember Eric Thieme doing loops at l'Almanarre with 4 sqm while everybody else was hardly planing with 5. This been said, there were withecaps everywhere that day. On other occasions you can have ~14 knts of wind, which is enough for lightweight sailors to plane on small gear, without noticeable whitecaps depending on spot orientation.
