I've been working on a 25 Hydra simular to the one you posted for a custmer of mine, that thing is a tank, and the cockpit is huge(full transom bracket boat). The cabin is a little weird, but its pretty big. I haven't spent any time in a 250 Wellcraft, so I don't know much about them, but it looks like you are stepping up beyond the 23 Formula/Seacraft size with this latest list.
I don't know if this one is still available, but its near by(me) and priced right
