Hi Mike,

Basically, one rule-of-thumb might be "a depth equal to the distance from
the ground to the subs waterline, trailer included".   (About 4 1-2 feet for
the NAUTILUS MINISUB).

You might get away with less water using rollers, a winch, and such; but my
trailer doesn't have those due to the shape of the NAUTILUS' keel.  I need
enough water on the ramp to float the sub free at launch, and also to
recover it.
