Hi Nick, welcome to the "Crazy Gang". Like you I fell in love with the Millenium Master when I first saw it at Friedrichshafen some years ago. Anyway there was an article in the UK magazine " Loop" in August this year and it appears it is now being manufactures in Latvia by a company called Pelegrin. Their website is
PELEGRIN. Performance doesn't come cheaply. A cruise speed of 144 kts but at a cost of Euro170,000. I wonder how many they will sell at that price? Can I have a ride when you get yours please?
