Introduction: revise necessary maths and definitions of physics, the weight schedule and buoyancy. Form definition: form coefficients and calculator methods for hydrostatics. Drawing of lines, fairing. Small angle stability: metacentric height (GM) and free surface. Large angle stability: GZ curve and dynamic stability. Construction: scantling tables, sources (and software). Principles of resistance. Model tests, standard series. Foils, rudders, keels and sails. Powering, propeller theory and selection, jets, thrusters and others. Sailplans, sail carrying power and hull balance. For a vessel of students' choice: design project. -- Course Website
