Don't confuse the inspections branch of the CG with the people who go out in
boats and aircraft to keep us safe. The latter deserve enormous respect.
For that matter, it isn't the fault of the people now in the inspections
branch that they are stuck enforcing regulations poorly written decades ago.

Sorry, Virginia, buoyancy is imaginary.

I enjoyed that piece. You probably make too much of your
"buoyancy is imaginary" thesis, but you use the same criteria for buoyancy
as everyone else, so what harm is that?

Roger,

Something more concrete.

I saw this boat that claimed to have "Angle of vanished stability 180
degrees."

I am more than slightly skeptical.

Would you posit an opinion?

That's another way of saying unstable when upside down. It's possible.
However, with the proportions of this vessel, it could only be true if you
include the buoyancy of that very tall and large pilothouse. You can
imagine how hard it would want to be floating back up if the hull were
upside down. I'm sure the stability picture would be a lot less rosy if the
pilothouse flooded due to broken windows or an open door.

I'd be skeptical until I had seen a complete stability booklet and could
review the inclining experiment.
