Field studies at Lock No. 8 on Welland Ship Canal show effectiveness of hydraulic assistance in reducing transit times of downbound vessels; ship traveling in restricted channel, such as lock, displaces water in direction opposite to ship movement; this reverse flow is accompanied by drop in water level along ship's hull; ship will squat or settle in water, therefore retarding its progress; introduction of water at upstream end of lock reduces back flow velocities and produces increase in ship velocity thus reducing transit times.
