Course Outline:
1. Ship Resistance. Dimensional analysis and similitude, Froude's method, wave resistance, ship waves, ship geometry and form coefficients, ship form and resistance relations, methodical series data.

2. Ship Propulsion. Review of airfoil/hydrofoil theory, actuator-disk momentum theory, cavitation, flow through propellers, blade-element analysis, propeller geometry, model propeller tests, hull-propeller interactions, propeller series, choice of optimum propeller.

3. Ship Motion in Waves. Added-mass theory, wave-body interactions, added-mass and wave-damping coefficients, rigid-body dynamics of a floating and submerged body, righting moment and metacentric height, wave forces and moments, description of sea states, ship response in regular waves, design of wave buoys.

4. Ship/Submarine Maneuvering. Analysis of dynamic stability, stability derivatives, experimental determination of hydrodynamic coefficients, hydrodynamics of control surfaces, design of a rudder.
