RT Book, Section T1 A research on motion smoothing of fast ferries A1 Cruz García, Jesús Manuel de la A1 Pérez de Lucas, P. A1 Aranda, Joaquín A1 Girón Sierra, José María Ricardo A1 Velasco, Francisco AB This paper is about a research on the use of active appendages to smooth the motions of fast ferries. According to BAZAN specifications, the research focused on a fast ferry with a T-foil and transom flaps. A collaboration of three research groups, with the experimental support of CEHIPAR was established to accomplish the objectives. The research was scheduled as two main steps. A first step of control-oriented modelling has successfully been achieved. The second step is dedicated to control design and experimental evaluation, seeking for the best solution. First experimental results confirm good expectations with the use of the active controlled appendages. This paper describes the main aspects of the research: the problem to be solved, the methodology and fulfilment of the research project, and the most relevant results obtained.
