First, let me lay down the only essential requirements for the boat
1. the boat is seaworthy of typical Gulf of Mexico offshore excursions
- non-hurricane but otherwise expected seas.
2. two people can live aboard without tripping over each other.
3. cost is no more than $30k, shipshape.
That's it.
What hull/engine combos offer the best MPG?
Anybody?

I'd recommend an older, used sailboat in the 28 to 30 ft range because
I think it's the only thing that will meet all of your listed
requirements. It would be very fuel efficient and easily handled by
two people after a bit of experience in fair weather. Get an
autopilot, best money you'll ever spend.
