Models of two existing ships were tested in model of Caughnawaga section of St. Lawrence Seaway, at various drafts, trims, and water depths, using dilute polymer solution to avoid scale effect; squat and steering performance were measured at various speeds, and passing maneuvers of two models were investigated; full-size squat data for 190 ships, measured by St. Lawrence Seaway Authority, are compared with theoretical drop of water level due to passage of ships and found to agree within acceptable limits, as do model tests; theory therefore permits estimation of squat, critical speeds, and safe speed limits imposed by considerations of water depth and draft, for any ship in any canal.
