A description is given of the flow phenomena which appear in a canal when a ship passes at a speed in the critical range. A brief discussion is included concerning the theoretical additional resistance of a ship, travelling at a critical speed due to the bore. This energy absorbing bore occurs throughout the critical range and travels ahead of the vessel.
Model resistance tests were performed and indicate that the additional resistance due to the bore substantiate the theoretical findings. Self propulsion tests also demonstrate that a ship can achieve and sustain a speed which is in the critical range if merely provided with sufficient power.
