Abstract
A simple model of the water flow behind a transom stern is presented. The water is assumed to separate cleanly from the bottom of the transom and it is considered that this domain of the flow is inviscid. Immediately aft of the transom is a stagnant region, in which the pressure can be computed on purely hydrostatic grounds. It is this hydrostatic pressure that acts upon the free-surface of the first water domain. Linearized free-surface theory is utilized to perform the analysis. The theoretical results for the length of the hollow and its profile area are seen to be much higher than the experimental data would suggest. It is thought that the source of the discrepancy is the hydraulic jump in the free surface which cannot be modeled using the current theory.
