Here is a design I did recently for some one else.
The spring loaded hydro foils are designed to break away if an under
water object is impacted. They also retract in flight for less drag.
The Mazda engine is turbo charged to 550 HP on gasoline. Of course
it can throttle back at low altitudes once out of the water.
Exceptional high altitude performance.

Paul, I like the concept. Can you crawl through the front wing to
get from one cat to the other? Ok, so we have head phones.
But why not retractable wheels as well as the hydro foils for
pavement landings? jd John Dinkel
Good idea. There is plenty of room in the hulls for retractable
wheels. The mechanism to do that is simpler, stronger and lighter
than that used to put the wheels in a wing.
Paul Lamar
Paul, did you have any more details on your cat-foil sea plane? Very
interesting design.
Thanks. Boyd Thompson
No the wings span and other aerodynamic details need working out.
I think there is some design software on the net. X plane or something
like that
You must have read my mind. I learned more about composite fabrication
working with Dan Gray and his crew. They turn out fantastic looking
composites in a relatively short time.
I was thinking of building one on the way back from the beach..
Take a block of blue Styrofoam 12 inches thick 48 inches high and 20
feet long.
Carve to the shape of one side of one fuselage.
You can add the tail verticals.
Cover with duct tape.
Lay up glass or carbon fiber on that. When cured slather on a white layer
of micro balloon paste. That is easily sanded to a smooth final shape.
Your done with one half of one fuselage. Repeat. The wings and tail
are made the same way.
That thin layer of micro balloons makes all the difference.
