    There are many rules for keel and rudder design and they depend on all the other dimensions of the boat. As a student I am sure you have many books to guide you. My favorite is "Princicals of Yacht Design" by Larson & Eliasson. Many amateurs get by with proportions, simple estimates, and proven profiles, but for college credit I think you are going to want to do the actual 3 dimensional force diagram and show that heel and leeway are not excessive and the boat has mild weather helm and plenty of rudder lift before stall for control and maneuverability.
