Please remember that the Wayfarer is a cruiser-racer. The bilge keels are essential whenever a boat grounds. Should the boat change significantly to accomodate a small minority who race the Wayfarer at a high level?
Could be worse… some big boat cruiser-racezrs (the Sigma 33) for instance, must carry a full cruising inventory on board…somewhat over the top when their championships are decide by 5 days of sailing windward-leeward courses.
On another topic… I vote for the inexpensive and effective swing test to establish moment of inertia – I prpose we measure all the boats at the next Worlds and use this as a basis for establishing a standard measure.
