Rumour has it that the VOR70s where designed for wakeboarders...

Nosediving and resulting broaches are already a problem with the Open 60 monohulls, I guess the VOR70 are not much better (Or probably worse since they are required to sail upwind). Bruce Schwab added a finn to the bow of his Ocean-Planet to prevent nosediving. Also the canting keels will take a pounding and IMHO its only a matter of time before one of 'em falls of.
