The paper treats the problem of crash-stop manoeuver which is of great importance for vessels navigating at restricted and overcrowded inland waterways. A brief review of existing international regulations covering stopping process on inland waterways is given. Three characteristic phases of crash-stop manoeuver for a typical Danube pushboat are described and a simplified calculation procedure is propsed for estimation of stopping distance and stopping time period for a vessel. A propeller's reverse thrust prediction during crash-stop manoeuver was determined according to results of W.B. series 4 quadrant open water testing. Simple emperical formulas for calculation of propeller's reverse thrust are given either for conventional W.B. series propeller and propeller series KA operating in nozzle type 19A. At the end, some concluding remarks are given on how to influence the stopping abilities of a vessel in design phase. The accuracy of proposed calculation procedure is illustrated through comparison to results of crash-stop trial testing for a pushed concoy and a cargo ship.
