Hi Gary,
It's the 1st time in 2 years the boat has been out of the shed! I am glad you enjoyed "Karma Cat" and yes they are similar vintage in fact all 4 hulls were built next to each other. They are both quick boats between them they have won many regattas.
I must admit I also enjoyed having a sail, you never know I might even go to another regatta soon.

Regards Ross.
