Okay that is a layman's undertaning but you got the main idea.
Fact: A blistered bottom is the result of untold hours of this pressure
gradient. Sometimes it takes years of submersion which creates the
pressure
gradient for blisters to occur. Osmosis is a
relatively slow process when

That's a matter of semantics, Bob. When something takes years I define that
as a slow process. If you, on the other hand, wish to view in geological
terms then it is, indeed, a fast process. In other words, stop quibbling.
pressure differentials on either side of a membrane are not great.
Fact: Spraying the blistered bottom repeatedly with fresh water does NOT
create osmosis as there is no pressure gradient.

Fact: No penetration = wishful thinking and NO effect upon reducing the
moisture in the soggy laminate that combines with layup chemicals.

And, just what that be and why didn't you say what it is?
Now, to the crux of the matter which is
.................. how to remove the moisture from the
laminate before coating the bottom with an impermeable 'barrier coat.'

There is only one way to accomplish this drying process and that is not by
osmosis but by diffusion through the membrane and evaporation of the
moisture at the surface of the membrane.

The chemical was created by mixing water with a thicker version of the
chemical. It is not an irreversible process that goes only one way. The
water in the chemical can evaporate away leaving behind the thicker version
of the chemical which is part of the lay-up process. The extended drying
process allows the watermolecules to diffuse through the laminate and
evaporate at the outer surface of the hull which is stored in a low-humidity
environment to speed up the evaporation process which, in turn, speeds up
the diffusion process. What osmosis brought in diffusion allows back out -
the water.
This process involves storing the
soggy layup in a low-humidity environment for a year or two so diffusion
and
evaporation can occur

You don't have to do a freaking thing other than store the boat in a low
humidity environment. The pressure wash in the slings will be plenty enough
to remove bottom growth and salt residue that might attract moisture and
slow down the evaporation process. Spraying it repeatedly is nonsensical.
and the hull can be tested with a moisture meter until
it reaches acceptable levels.
::

That's where you totally incorrect. When stored in a low humidity
environment the hull has NO CHOICE but to dry out because of the laws of
physics. It doesn't matter one iota if anybody is watching it or not. It
will happen even if everybody on the Earth were to drop dead.
I welcome any rational, enlightened explanation of how spraying the hull
with water can possibly negate or supersede the above facts.

No, you are and I just proved why you are. You, like the other mental
deficient's in this group, have a very incomplete understanding of basic
physical processes.
Now, run along and bash Joe. He's more your speed as he's too stupid to
