Rudder Placement and Size in Relation to Prop on Submarine

Designing next year's submarine for the University of Michigan's Human Powered Submarine team and am struggling to find information on efficient rudder placement and size. I know the rudders must be placed aft of the center of gravity of the vessel, but is their a relation or constraints for rudder/hydroplane length in relation to prop length, or is that mainly applicable to vessels with rudders aft of the prop.

 

Welcome to the forum.
First, get a copy of SNAME's Submersible Vehicle Systems Design. The hardcover is orange and somebody on the staff should have a copy. Most of what you need is in there. Then start a conversation with me, because an open forum is not the place for some topics.
