Zueg,
Nucking Futs has pretty much the exact boat you are looking for. Runs 70 or better with very modest power 450-550hp, is 20', and looks good to boot. As far as I know, it is for sale, and it's not the kind of boat you'd have to change anything around on to make it right. Hack Job is building up the same hull now produced by Dana Performance boats as the SW20. If you wanted to go the "from scratch" route, that would be the way to start. I don't know how much "hull and trailer" business Rhett at Dana really wants to get into, but it wouldn't hurt to give him a call. I'm really looking forward to see what kind of #s Hackers boat puts up with 735hp in it. He'll probably get it wet the weekend after the 4rth or thereabouts.
You've probably seen it around on the boards.

It doesn't have the same lines as say a Spectra or Schiada, and in that sense, I don't know if I'd call it a "cruiser" but it sounds like it would suit your needs pretty well.

So did this boat ever hit the water?
