[PCW] Air cushion between catamaran hulls

[Robert Deering]

Put a different way...

A catamaran running at speed through waves has a lot of very complex forces
and interactions going on between the hull and the water (and the air).
Water is some 800 times denser than air, so the effects of the water on the
hull are going to easily drown out any effects by the air.  A boat operator
running his boat in those conditions simply does not have enough of a
controlled experiment going on to be able to isolate the two effects such
that he can make any objective claims.

It would certainly be an interesting experiment to set up and perform, but
I'm not smart enough to know how that could be done.
