NOTHING is more fair than sailors sailing boats that are setup identically. Nothing pits sailor skill against sailor skill in the same way. It's a different, and IMHO, the most humbling and pure way to compete. How you setup your diamond wires does not make you a better or more deserving sailor.
Jake,
BUT boat tuning for crew weight is critical. Is it fair if the lightweights get an overpowered boat; the heavies get an underpowered boat and one team gets a boat that is set up properly?
I think the event is a fine idea; but struggle to see the fairness of tuning the boats to suit only one crew weight.
