The consensus is that gybing boards worked well in some conditions, but not others. The Infusions built in the last few years all have the boards fixed (not gybing). According to many racers, the added clearance in the trunk also placed additional wear on the trailing edge, causing chipping of the boards. Most everyone I know has now bogged the trunks up so that they do not twist in the trunk. (Nacra may confirm this if you ask them.)
$800/ea is quite steep IMHO. 500 or so a piece seems more like it. Try New England Catamarans. Rick may give you a better price.
