Yes, the engine room is outstanding - at least it was at launch (those are the launch photos from "about 6 years ago" and before a "major refit").
But I'm not liking the livability of the interior. Look at the steep ladder into the aft stateroom. Look at the lack of stowage around the "bed" (different than the plan). Notice all the small changes in the height of the sole in the saloon & galley. At least it was built with a more central galley than shown on the plans. And, while I guess this is common to all of Buehler's designs, to me it feels like a submarine below. And then there's the complete absence of handholds throughout (maybe that has been rectified).
Even the helm station gives me pause. Smaller than shown on the plans, off the centerline, partially raised, probably necessary to see over the starboard bullwark, but it looks like there's still a blind spot off the bow to port. No apparent provision for electronics and across the passageway from the rather minimal "chart table". It would be interesting to see how this has evolved since the launch.
But I do like that engine room!
Edit: Grovelling for info on the "non-turbo Iveco", it looks like this is their N67 MNA M15, which in it's most powerful version produces 150hp at 2800 rpm. So that's why the engine room is so spacious. And looking again, am I the only one concerned about that unsupported wet exhaust hose?
