Or along the keel with "air funnels" over the shutter areas. To balance this upward force would employ the same principles Bedford and Cavor used on their sphere. Panels placed in locations to offset and balance out other directional effects. Helm control may be supplemented by shutter control. All highly complicated of course and shutter damage in combat would make some pretty interesting control issues.
At least...that's one way to look at it.
Hydrogen, on it's own, will escape the lower atmosphere eventually. It's pretty light, and would tend to stay on the outer portions of the enviromental envelope. Given a little push from solar radiation, it will eventually escape the atmosphere. Good thing water is a stable molecule, and hydrogen so reactive, or it's goodbye oceans. :-)
Cavorite is even more so, it would escape the atmosphere, not because it's light, but because it cuts off any gravitic interaction.
Zeppelins float, largely because they are - due to their EFFECTIVE density- lighter than air.
You would structure an 'Aeronaught' (I submit we sue this term, to avoid any nasty copyright problems with 'Aeronef' - unless there's some copyright problem with 'Aeronaught') in such a way that the vast majority of the ships bulk is hidden by the cavorite shell. Any excess outside of the cavorite would be affected by the Earth's gravity. This portion that is drawn to the Earth would need to be just enough to make the ship neutrally bouyant in air. You could make it more or less bouyant by the use of your shutters, and use internal propellers as ducted fans to manuever. You could also hang your main engines outside the hull ala the old 'Zeppelins'...
You'd have 'updraft' from the force of the air above the ship moving very quickly upward, as it is suddenly weightless. BUT, the inrush of air would also tend to mix with the air above the ship, and negate any atmospheric losses on the Earth's behalf, as the air entering would push the weightless air back out of the cavorites influence. You have turbulence, but not anything catastrophic like loosing all the Earth's atmosphere to space - despite a novice's observations that such would be the case in Well's book.
You'd get some 'interesting' climb rates if you happened to pass over another ship, though....
:-)
I would tend to think that large ships would be the norm, as smaller ships would have less of a margin of safety in respect to it's bouyancy reserve.
You could also run steam systems aboard Aeronaughts, as you 've probably got room to put in a cooling tower for the steam condensers in the larger ones. The smaller 'naughts would likely run like old steam locomotives and be very overpowering at short ranges - but run out of water rather quickly as they haven't room for cooling towers - and so simply vent their used steam to atmosphere like the old steam locomotives did.
Cannonball Express, anyone?
