So perhaps there is a fourth class of boat.
1. Formula one design (F18)
2. International one design (Tornado)
3. Manufacturer's one design (Laser)
4. Manufacturer's one design with mucho product innovation (Tiger)
Just FYI, the Tiger is an International One-Design Class, along with the H14, H16, H17 and TheMightyHobie18. The manufacturers cannot make changes in these classes willy-nilly (although Hobie Europe tries with the Tiger and most recently with the addition of a spinnaker to the H16). Changes must be submitted by the Class Association and approved by ISAF - not a rubber stamp, BTW. The manufacturers have a say in the class rules of these classes, but they do not control them.
