This is from ISAF.
"Tuesday at the ISAF Annual Conference in Helsinki, Finland, equipment
was the hot topic, with the classes coming under the spotlight at both
the ISAF Women’s Sailing Committee and the Equipment Committee. Looking
towards the London 2012 Olympic Games, the Committee gave their approval
to Submission 079 to delete Regulation 16.1.6, which currently limits
the classes from which ISAF can choose the equipment for the Olympic
Games and Regional Games. Here’s the verbiage of the regulation: The
equipment for the Olympic Games and all Regional Games shall be chosen
from the following classes:
- Windsurfing: Funboard, Formula, Mistral, Neil Pryde RS:X
- Single-Handed Dinghy: Finn, Laser, Laser Radial, Sunfish, Byte,
Zoom, Europe
- Multi-Crewed Dinghy: 29er, 420, 470, Fireball, Flying Dutchman,
Lightning, Snipe, 49er
- Keelboat: Etchells, Flying Fifteen, H-Boat, J-22, J-24, Soling,
Yngling, Sonar, Star
- Multihull: Hobie 16, Hobie Tiger, Tornado"

Will it still be only one multihull medal?
Why consider the Tiger over the F18 (formula class not Nacra)? Other olympic classes such as Stars and Tornado utilize multiple manufacturers of hulls and rigging for a class. It would be like only consideringa Marstrom Tornado, not another manufacturer. My 2 cents.
