Paul,
Air bubbles under the hull?  Wouldn"t that cause more
turbulance unless vented in a low pressure location?
This is an idea that I had thought of for a boat.
(patent applied for as you occasionally say!!)  :D

It has been proven to work. Air has less friction than water.

 This was the original idea that lead to the hovercraft.

 I loved a ride in the channel hover craft.

 I recently rode a smaller one back and fourth from Portsmouth
 (South Sea Hoverport) to the Isle of Wight.

 It was also the focus of a bunch of tests done by the navy on high speed
torpedo's..
I think they had a fish that normally did ~30knt up to over 100 using some
form of a
gas release deal on the nose of it.. [not sure of the finer details, and
it's possibly an
old wives tale.. I've never looking into it too deeply..]

Fwiw

Also the screen of bubbles reduces the sonic signature of surface vessels,
from both active and passive detection.
Flank III was a classified speed, but we actually had a rooster tail, and
could outrun torpedos. Musta been the bubbles. ;-D
