Paper presents activities of the GUT Experimental Centre in Ilawa in the recent years. Its main tasks have been organizing international student scientific camps and sailing courses for GUT students. For that purpose the laboratory and hotel facilities of the Centre have been modernized and new measurement techniques implemented. The conclusions outline possibilities of future use of the Centre.

Paper presents model tests of fast units carried out in the years 1956-2000 in the Experimental Centre of the Gdansk University of Technology Shipbuilding Institute on Jeziorak Lake. The experimental tests included single- and twin-hull hydrofoils, amphibian hovercraft, side-wall hovercraft and also speedboats and SWATH type catamarans. The aim of those tests was to acquire data for developing the design and safety criteria as well as computer programs for predicting the hydrodynamic properties of fast units. The gathered experimental material was used in the theoretical studies, publications and conference papers.

At present, we have well-elaborated theory and practical methods for predictions and investigations of hydrofoil craft longitudinal motions in regular waves and in wind waves. Whereas in the field of lateral motions, works are concerned in pure rolling or stabilization for deeply submerged foils. Therefore, in the paper, the more general linear mathematical model and practical method for investigation of lateral motions characteristics of hydrofoil craft are outlined. The new model of craft motions comprises coupled swaying, yawing and rolling when hydrofoil craft is flying, at any courses relative to main direction of wave's propagation in a fully developed rough sea. Using the method, many investigations are performed and some results are presented.
