THE SQUAT OF FULL SHIPS IN SHALLOW WATER

The problem of sinkage and trim while underway in shallow water (squat) is discussed and its accurate assessment for the large ships of today is shown to be important. Some results of experiments to measure the squat of full-form ship models are presented and discussed and a semi-empirical theory is developed which predicts model results with reasonable accuracy. Full-scale measurements of squat have been obtained on a number of ships. The method by which this has been accomplished is described and some results are presented. These in turn are compared with model andd theoretical predictions and the measure of agreement obtained is encouraging bearing in mind the overall accuracy of the measurements.
