You cannot hover at depth, unless you have some sort of vertial thrusters.
How slow you can do depends entirely on the design of the "wings" (i.e.,
how much downforce they produce).

Your post appears to have been cut off, but visibility is certainly an
issue. I wouldn't want to use a flier sub in murky water.

Like I said, there are trade-offs. But they are fundamentally different in
a number of ways, and the same rules do not always apply WRT "normal"
submarines, which was my original point.
