The real showstopper (besides Maltese Falcon) was this "X-stream" 73 m Concept model from Feadship and de Voogt Naval Architects. They were x-streamely proud of it as well and with all rights!
The pods were electric and the props on shafts was supposed to take over with dieselpower for higher speeds, I think they said 12/24 knots as the general idea.
(sorry about the picture quality, she was rotating in a round plastic cover...)
