I rode in a BIG hydrofoil in Hawaii some years ago. We went from the
airport
to Maui by boat. It was VERY smooth all of the way. We heard that the boat
following ours broke down at sea and everyone was sea sick wallowing in
the
waves. Of course, that is not a fair comparison to a V hulled boat when
under way..but...

I believe that hydrofoils are smoother than V shaped hulls when under
way.

Somewhat the same experience in Sidney harbor. They run a hydrofoil from
Circular quay to Manley Beach. Did give an odd sensation and would slowly
rock side to side. Gave the feeling that the boat was slightly unstable,
and sort of chine walking. I don't know of any big hydrofoil boats anymore.
Most are big catamarans. Better carrying capacity and cheaper to run. The
fast ferry from Barcelona to Majorrca is 97 meters and runs 47 knots. We
did slow down coming back as there were some 10' seas. The whole ship would
shudder when it hit a real big wave. 150 miles going 3.5 hours, returning
4.25 hours. This is a ship with capacity for 800 passengers and 300 cars
and some semi's.
