but if the air hull fills with water it will sink...
the foam hull won't...
that's not the question though is it... : )

Just for one more twist and to see this through
Well here's the theory..
We have two identical hulls hermetically sealed.
One with our world famous foam the other with compressed air.
The compressed air one will be pressurized until the weight of both hulls are exactly equal.

Which hull would take on more weight before being swamped???

The foam filled one, no doubt.
Consider this: Pounds Per Square Inch - the air hull would have to be considerably thicker to withstand the PSI in air needed to equal the weight of the foam.

10 PSI applied to a 10 square inch area can lift 100 pounds.

Just a thought

Just to state the obvious, adding foam would mean more weight and thus displace more water. But that would not translate to having the ability to carry less as that would prove to be on the advantage as compared to the boat with just an empty shell. It would carry more but the one with foam, in my opinion and experience with boats, would be much stable across the water, in normal real world conditions. But when put on a controlled environment, I would think only a few measures would determine the capacity.
