Some interesting discussion.
It seems that as I suspected, cat sailing world wide is only moving along slowly and it would appear that there is not a lot of effort being made to promote it. There's plenty that could be done but it seems there's a shortage of dedicated people to do the work. It's usually left to volunteers to do the organising but it's always difficult to get people to put their hand up as it's often a thankless and time consuming job.

I too think that the established manufacturers have much to answer for. I know sales are down and the profit margins are small but there seems to be plenty of money to put new boats on the market (F18/F16/Extreme 40, more and more cruising designs etc) but it's very short sighted to leave the very crucial recruitment of potential users to amateurs. Just my 2c worth.
