Hi Alan

Not sure if your main interest is racing , but just in case ,- Mystere also makes a great very similar Formula 18 w spin .

The N A Formula 18 championships are in Quebec in 04
not too far away , It would be an interesting and fun goal with a new F-18 cat to practise and train on to race in it. The spin snuffer rigged cats do require a good crew and take some additional time {and spills} to learn if your not yet familiar with spin rigged catamarans .
This F-18 group may provide a larger race organization and class events to sail in over time.
