One of the shelved projects/ concepts (1998) is this hydrofoil Riva style.
Carbon fibre hull and foils.
The Hull wood veneered to give it the old style look.
Ride height control through feeler,
propulsion through prop,
or alternatively induction engine with nozzle propellor.
Little youtube movie here.
Got to work on the concept a bit more.
Need to be come a full time designer.
