AIMS AND CONTENT LEARNING OUTCOMES The course is targeted to the acquisition by the students of the basic principles and the basis for resistance to the motion and to power the hulls . AIMS AND LEARNING OUTCOMES The course aims to provide students with the basic knowledge and methodological tools necessary to carry out the prediction of the resistance to motion of a hull, with reference to the influence of the geometric characteristics of the same and their influence on the resistance as well as the basic knowledge and methodological tools necessary for the choice of the maximum performance propeller for the hull itself. Through the notions learned during the course, the student must be able to identify the implications of the choices related to the geometric characteristics of the hull and the propeller on the overall performance of the hull-propeller system. The student must demonstrate that he/she is able to interpret the results of towing tank tests of hulls and propellers and to be able to use them to carry out a full-scale operating prediction. The student must be able to solve the problems concerning the prediction of the resistance of a hull and the choice of the maximum efficiency propeller. TEACHING METHODS The teacher will use lectures for about 80% of the total hours exercises, both in class and at the Towing Tank, to practically deepen theoretical aspects for about 20% of the total hours. Students with valid certifications for Specific Learning Disorders (SLDs), disabilities or other educational needs are invited to contact the teacher and the School's disability liaison at the beginning of teaching to agree on possible teaching arrangements that, while respecting the teaching objectives, take into account individual learning patterns. SYLLABUS/CONTENT Main problems of fluid-hull interaction, references to the equations of hydrodynamics and the homogeneity theorem, principle of similarity. Components of resistance to motion: tangential resistance, boundary layer, frictional resistance, flat plate resistance, hull surface, viscous pressure resistance, form resistance, induced resistance, wave resistance, wave field generated by a hull, absorbed energy, interference, bulb, resistance due to breaking waves, resistance of appendages, air resistance. Parameters that affect the resistance to motion. Tests on hull models, presentation of results, systematic series of tests and statistical methods. Tests on propeller models, diagrams of the isolated propeller, cavitation, propulsion coefficients, self-propulsion tests, systematic series of propellers, problems related to propulsion, propeller design, operating prediction.

For current students, there are three sessions in the summer session (June, July and September) and two sessions in the winter session (January and February). For students who are not on track with the prescribed course, in addition to the sessions described above, there is one exam session per month in the remaining periods. The test consists of: n.2 questions in which the candidate will have to illustrate the proposed topics, and how these are applied to solve the classic problems of Naval Architecture. ASSESSMENT METHODS The examination aims to assess the student’s ability to address and solve typical Naval Architecture problems, with particular reference to recreational vessels. The assessment consists of two open-ended questions relating to topics covered during lectures and included in the course materials. The evaluation of the student’s responses will determine whether they have acquired the theoretical knowledge and practical techniques presented throughout the course. The final grade will be based on the following criteria: Mastery of the course content; Understanding of the relevant physical phenomena; Clarity and accuracy of expression; Ability to analyse and solve technical and engineering problems.
