Sailboat Keel Design

This lecture covers the design aspects of sailboat keels, focusing on the impact of keel shape and size on the boat's performance. It discusses key parameters such as Reynolds number, drag force, and keel wings, emphasizing the importance of reducing induced drag. The presentation also delves into the resistance components of sailboats, including water deflection and hull speed. The instructor explains how keel design influences the boat's motion and highlights the significance of elliptic or tapered trailing edges to minimize drag.
