I have tested the hull with a Mercury 300XS racing outboard on the back; with 35 gal [132 l] of fuel she came in at 2,646 lbs [1,199 kg]. On the water we managed to get 70.1 mph, but we could only get 5,700 rpm out of the motor.

Full-aeration requires a more active system (pumping air bubbles) vs. passive system (step bottom hull). Mitsubishi has come out with an 'air lubrication system' for the shipping industry which creates a carpet of bubbles under the entire hull of the ship. This is where boat racing should be headed.

Hallett had a hull design a few years that had holes on the side of the boat that directed air directly into the front part of
each step , they have since changed the design completely, and now use a semi-tunnel at the back ...very interesting .

Pretty sure this has popped up before, but yea stopping like it has brakes tells you something is way wrong. I can't imagine that those little holes could move enough air to out weight the drag of all that crap you would drag through the water. remember to get the hull to pull air down you must create a vacuum (drag). The question any aerated hull must answer is does does the ends justify the means. 2646 lbs and 300hp should do better than 70
