Since IWR activities appear in our academic life, about ten years ago, they have substantially changed the atmosphere in study of naval architecture on the Faculty for mechanical Engineering and Naval Architecture in Zgreb. The education in shipbuilding becomes an exciting study in broader sense. And it is not only education, the study is now, thanks to waterbiking, also an efficient and entertaining way for interchange of versatile experiences in communication among colleagues from many universities. The design and construction of vessels is an outstanding method to check student’s engineering and managing capabilities. There is no better way for application of the theoretical background on practical problems. The practice of organising IWR on different places offers opportunities to acquaint new people and new countries. Moreover, by preparation for IWR, precious skills and useful practice have been gained by looking for sponsors, searching for support and solving organisational problems. IWR activities promote engineering studies and attract young people to join technical schools and faculties. The contacts among the teachers and students contribute to better co-operation among universities. There are so many benefits of waterbiking and not any disadvantage that IWR make all the enthusiasts very happy. The University of Zagreb, The Faculty for Mechanical Engineering and Naval Architecture and the Department for Naval Architecture and Ocean Engineering accompanied by the Craoatian Association of Students of Naval Architecture strongly supports the waterbike activities.
