CODE 66399 ACADEMIC YEAR 2025/2026 CREDITS 6 cfu anno 1 YACHT DESIGN 11958 (LM-34) - LA SPEZIA SCIENTIFIC DISCIPLINARY SECTOR ING-IND/01 LANGUAGE English TEACHING LOCATION LA SPEZIA SEMESTER 1° Semester MODULES Questo insegnamento è un modulo di: YACHT STABILITY AND DYNAMICS OVERVIEW The course deals with three main topics: - manoeuvrability (basic motion laws, standard manoeuvres, control means, manoeuvrability rules, different approaches for the evaluation of the manoeuvring characteristics) - seakeeping (basic motion laws, response amplitude operator, sea spectrum, ship motions in determined conditions, operability, stabilizing devices) - dynamic stability AIMS AND CONTENT LEARNING OUTCOMES The teaching deals with the motion law definition as well as the hydrodynamics characteristics regulating ship and yacht behaviour from the manoeuvrability, seakeeping and dynamic stability sides. TEACHING METHODS Lessons on the different topics, Classwork for the development of a simplified manoeuvrability code (in Excel) SYLLABUS/CONTENT Part 1: Ship Controllability (Introduction, Governing equations, Motion Stability, Manoeuvring characteristics and standard manoeuvres, Summary of existing rules, Model tests / Simulation, Steering devices / Rudder design, Slow speed manoeuvrability / Shallow and restricted waters, Planing crafts manoeuvrability) Part 2: Seakeeping (Introduction, Linear systems – a review, Ship responses in regular waves, Ship motions – governing equations, Numerical approach (brief overview), Typical Response Amplitude Operators (RAO), Ship motions in irregular waves, Wave spectra – Response spectra, Ship Operability (short and long term), Means for active and passive stabilization of ship motions, Planing crafts seakeeping) Part 3: Dynamic Stability RECOMMENDED READING/BIBLIOGRAPHY Lecture notes (given during lectures) Principles of Naval Architecture vol.3 TEACHERS AND EXAM BOARD GIULIANO VERNENGO Ricevimento: On request, by sending an email to the professor (giuliano.vernengo@unige.it).

There are three exams in summer (June, July, September) and two in winter (January and February), plus some additional exams during year to be agreed with the professor. The exam will regard coursework had during the lectures and theory (usually two questions). ASSESSMENT METHODS The oral exam will consist in the verification of coursework carried out during lectures and in the verification of the level of knowledge gained by the student. The oral exam moreover will allow to evaluate the communicating skills of the student. FURTHER INFORMATION The students have to sign up for the exams via the online website.
