Frankly, I'm a little surprised that only one "pump" per wave is allowed (subject to apparent variations in enforcement from regatta to regatta). I would think from a purely athletic perspective that pumping, ooching and sculling would be aggresively encouraged in such a small boat to feature the vessel's planing abilities and strong, fit, smart skippers. If deep in the annals of small, one-design racing it was decided that the difference should lie in the sailor and not the vessel, then wouldn't kinetics be an incumbent element in that goal? I'm not at all knocking the current system, all I'm saying is that I think it would be more fun (at the very least from a spectator viewpoint) if at least one more race was added to the schedule at some regattas with full kinetics.
