I was thinking that another major difference is the typical
commercial blowing application is into a larger open area,
where low velocity and gravity do the work while a high
velocity air streem could end up blowing away insulation
that had already been deposited unless it moves the
insulation at a very high rate relative to the air volume.

On "This Old House", a couple insulated their home with a rented
commercial blower. They removed single sections of their siding at the
top and near the bottom, to blow the insulation from the bottom up and
then from the bottom down. When they finished blowing the insulation,
they plugged all the holes, and replaced the original sections of siding.

Ok but do you see what I'm saying about the airflow rate?
While a commercial blower "might" have similar CFM, it would
tend to have lower air speed which would be more likely to
leave insulation in place instead of blowing it away from
the area you're aiming at. Just a thought, I've no idea
what this boat panel area is like.

That must have been an ooold issue. "This Old House" has done
nothing but expensive rebuilding of antique houses for many years.

Actually, it wasn't on "This Old House" but an "Ask This Old House"
episode. Forgot the program title when I wrote that reply.

I like the more moderate income jobs but OTOH I'd never see how they dig
an extended foundation, or make asphalt or repair stained glass. They
should put some of the "This Old House" renovations on DVD, one
renovation per DVD or something.
