The paper was set up to analyse the research and development issues related to human computer collaborative learning in teaching and research field focussed on surfboard fins and their performance. It presents the results of a systematic study of optimising fin design features by means of a computer. This design approach is taught as a part of Surf Equipment Design Materials and Manufacturing Science Course in Surf Science and Technology (SST) degree program at Edith Cowan University (ECU). It is based on 'reported' airfoil data for a variety of wing sections and relevant fluid motion patterns assuming that those quantitative 'empirical' data could be equally applicable to fin designs because of strong similarities in geometrical features of wing sections with fin sections. The design process developed at ECU involves a constant student computer interaction. This paper describes in more detail the student computer Interaction in designing surfboard fins. The results are discussed in terms of modified geometry and performance in surfing. Additionally, the paper provides various examples of fins made by Surf Science and Technology (SST) students In laboratory conditions at ECU.
