Cosimo

A 45ft. express cruisers utilizing a combination of hydrofoil technology and O-foil technology. Its main purpose is to provide a smooth ride for the users while achieving high level of sustainability and marine life friendliness.

With the hydrofoil, it raises and be able to reach high speed on calm water. In rough water, it would have the advantage of monohull.

With the O-foil technology, it helps increase efficiency thus reduce fuel consumption. Also, with this unique propulsion, no turbulence would be generated thus prevent damage to the marine lives.

Sketch Models

I created some pink foam models in order to explore the form and experiment with different designs

Final form Design

This is the form that I decided to use for the final design. What I like about it is the continuous curvature from bow to sterm and from top to bottom.

Oscillating Foil Technology

Oscillating foils (O-foil) uses the motion of the hydrofoil to create a forward force to drive the boat. It was inspired by the flapping motion of many marine fishes and creatures. Multiple companies and experts across the globe are experimenting with this oscillating foil technology.

Efficiency

O-foil has almost 90% of propulsive efficiency comparing to Normal propeller propulsion technology nowadays only has around 50-70% efficiency.

Environmental Friendly

With better efficiency there would be less fuels used thus less pollution. Also, O-foil doesn't produce way less noise and turbulence unlike propellers which would affect the marine lives and destroy the whole life cycle.
