Model tests of the resistance, propulsion and manoeuvrability of ships in the Experimental Centre in Ilawa

Paper presents the development of resistance, propulsion and steering quality model tests carried out on lake. Such pioneering investigations began in 1956 and were gradually improved and extended. Original equipment and measurement methods were developed. The paper presents those research methods and techniques,and also accuracy of the results, in a historical perspective. Described are also several most important research programmes accomplished in the Centre.
