The Tiger design is managed by a group that is intent on it being a competitive F18. Hobie USA doesn't have a great deal of control over it's configuration - IMHO, while I don't agree with the logic, they've done a pretty decent job in configuration control to maintain some fashion of Hobie One Design racing with the Tiger. My point is, the priority of the Tiger design is for F18 racing so the only reason I would suspect you haven't seen any major changes is that they continue to be comfortable with the performance of the boat.
