An account of research activities on the devices improving the manoeuvring abilities carried out at the Gdansk University of Technology were presented in Part I of the paper. Experience from implementation of open rudders on real ships is presented in Part II. Open rudders were fitted on two full size ships: a 1000BHP harbour tug and a 2500 BHP long line fishing vessel. Designs were made for four types of ships:motorsailing passenger ship “Gwarek” (2 x 1.032 BHP and 1800 m² sail area); arctic expedition sailing ship m/y “Polarex” (length 40,4 m, 1200 BHP); rescue vessel R-27 (two engines à 600 BHP with single propeller); harbour tug m/t “Atlas” (2500 BHP). None of these designs was implemented due to financial difficulties of the owners. Further model experiments with a self propelled model of a cargo liner m/s “Hollandia” exceeding 20 knots were carried out on the lake as well as with a model of a twin screw vessel
