True I see your point, to the spectators 2v2 will be easier to understand. It absolutely makes sense. Just to the actual sailor spectators 3v3 would likely be more exciting and interesting. It just would have been cool to see some high speed pass backs, kind of hard in 2v2. Also, the more plays that come in with 3v3 would be create more actual team racing.
The arguement from monohull sailors is that cats arent maneuverable enough to really team race, it's a bit easier to win a 2v2 with raw speed than a 3v3 which would give all the skeptics more to support their arguement.
Just food for thought. I absolutely agree on simplifying it to appeal to non-sailors.
