Tony,
You would still need to add enough weight to sink the argon would you not?
And would that weight not be equal to the weight of the water the second
hull was displacing?

Actually it's not such a bad idea, if you pressurize the second hull with a
gas like Argon or Nitrogen you should be OK in the kinetic energy
department,
you could even use the entire second hull as a dropweight.
