2. What is a Rigid Wing Sail?
How does it work?
Airflow creates lift
“Pulls” and propels a Sailboat, “Lifts” a plane

3. Points of Sail and Apparent Wind
Basic Sailing
A wings best friend

4. Rigid Wing vs. Soft Sail Easier to Handle Lift/ Drag Wears Out
Cheaper
Lift/ Drag
Holds Shape
One size

5. The Problem Prohibitive costs/skills for A and C-class catamarans
Wings are not Commercially Available for Small Scale Radio Controlled Sailboats
No easily accessible plans for either

6. My Solution Buy an existing RC Catamaran
Design and Build a Rigid Wing Sail
Put them together
Make what I learned Accessible

7. Engineering Theory Aerodynamics of the wing Fluid dynamics of the hull
Mechanics of the system

8. Engineering Technology
Radio Control
Wing Camber Adjustment

9. Engineering Design
Design and optimize a wing shape and size according to the type and weight of boat through iterations

10. Awesome
