There's a Ghost dinghy up for sale on Facebook. I thought all of these were long gone - I don't think I've ever seen one. It was basically a 15ft 60s style Cherub, designed by Greg Gregory who did a lot of UK Cherubs at that time. Pole kite, long pole for the time, Large jib, highish aspect mainsail. The concept was reasonable, but I've heard the end product didn't quite come off. Interesting though.
