I've got an idea for a houseboat to maximize space, by putting in an
overhead berth. I want standing headroom under the berth and am
wondering if I've got enough room to do it. This isn't a commercial
houseboat, but it's a conversion from generator barge that I built and
may not be able to sell at a decent price. So, what do y'all think is
the mininum space needed (no wisecracks either)?

They put 'three high' in a compartment on the Aircraft Carriers. It's about
28" (mattress to overhead) in each one if I recall.
