Found this and thought it would be a good thing to get on-board with the petition against it:

The RYA has recently made submissions to ISAF to remove the catamaran as a youth boat for 2009, and to remove the catamaran as an Olympic boat for 2012.

http://www2.sailing.org/meetings/2007november/papers/Sub_129.pdf
http://www2.sailing.org/meetings/2007november/papers/Sub_103.pdf

These submissions by the RYA were made without any consultation with the sailing community. We request that the submissions are withdrawn before the ISAF conference in early November and replaced by alternative submissions which support the use of catamarans both in future Olympics (2012 and beyond) and for youth training.

Please send this petition to all of your sailing friends.
