a) FUNDAMENTALS OF AERODYNAMICS AND HYDRODYNAMICS OF SAILING BOATS

Aerodynamics: Lifting theory for thin profiles, Determination of sail coefficients, Laboratory tests, Numerical methods.

Hydrodynamics: Hull forms for sailing yachts, methods of power prediction for sailing yachts hulls, Systematic series for sailing yachts hulls (Gerritsma), Equilibrium of aero and hydrodynamic forces applied to sails and hull, Keel effect on sailing boat equilibrium, Keel design, VPP methods.

b) HULL STRUCTURES

Materials: Wooden boat, Light Alloy hulls, Single skin composite boats, Modern sandwich technologies for yacht construction (vacuum, SCRIMP, infusion)

Structure lay out: Structure typology for wood, aluminium and composite hull, Construction and yard facilities technologies methods

c) MAST AND RIGGING
