I recently took a tour of the factory and saw the mould that is in development for the 23' and a mockup of the helm layout. I concur with the 'no twin' statement but I think it will be able to handle up to a 250hp engine (but don't hold me to that). The layout of the boat is going to be awesome though. I may have to make someone a great deal on my new 215 next year!
I'm not sure what Triumph can tell us at this stage about the boat (understandable as it is still in the design phase and production won't start till next year), but I'll try to find out.
