AIMS AND CONTENT LEARNING OUTCOMES The course is aimed at the acquisition by students of the fundamental principles relating to the resistance to motion and propulsion of hulls. AIMS AND LEARNING OUTCOMES The expected results of the module are an advanced understanding of the fundamentals of naval architecture and the development of the ability to set up a conscious study on boats. PREREQUISITES To take the exam for this course, you must have taken the following exams: GEOMETRY OF FLOATS / PRINCIPLES OF STATICS AND GEOMETRY OF FLOATS TEACHING METHODS The course is delivered through lectures and exercises carried out in the classroom.

For current students, three exam sessions are planned in the summer session (June, July and September) and two exam sessions in the winter session (January and February). The test consists of: n.2 questions in which the candidate must illustrate the proposed topics, and how these are applied to solve the classic problems of Naval Architecture. ASSESSMENT METHODS The student's evaluation is carried out during the oral exam and is based on the ability to describe autonomously, with coherence and propriety of terms the topics and demonstrations presented in class The attribution of the grade will take into account: Knowledge of the topics covered Understanding of the related physical phenomena Ability to present Ability to solve problems FURTHER INFORMATION Students with disabilities or DSA can request compensatory/dispensatory measures for the exam.
