Tubercles are the small bumps on the leading edge of the fins of humpback whales which improve their mobility. This project investigates whether adding tubercles to sailboat foils can improve the lift and increase the stall angle of the foil. After construction of suitable foils with and without tubercles, testing was performed in both a home-made flow tank and in a river.
