Basic principles and design calculations in naval architecture; terminology, delineation of hull form, loading and stability, trim, and effects of flooding; freeboard and tonnage regulations; introduction to design of hull structure; nature of resistance and its variation with hull form and proportions; and introduction to propellers and propulsion. Basic theories in maneuvering and sea-keeping characteristics, computer application in naval architecture, and ship design.
Dynamic response of a ship in regular and irregular seas, the equation of motion with six degrees of freedom, added mass and damping coefficient of an oscillating ship on the free surface, coupled equation of motion of a ship in waves, and description of ship motion in the irregular sea with the discussion leading to nonlinear equations of motion.
Planing craft, life, drag, wetted area of hull, appendage drag, direct and indirect propeller effect, spray formation, impact loads in smooth water and waves, porpoising, rough water behavior, and tank test procedures.
