A 2D+t method is applied to cases of planing boats in shallow water. This method approximates the three-dimensional flow around the boat by several two-dimensional flows in earth-fixed transverse cross planes. The two-dimensional flows are treated as fully nonlinear potential flow and solved using a boundary element method (BEM). Therefore, this method captures many important features of the flow around fast planing vessels while being very efficient at the same time. The obtained results are compared to experimental data and to the results of simulations performed with a method solving the three-dimensional Reynolds-averaged Navier-Stokes (RANS) equations. These simulations are used to investigate the flow in more detail. Limits regarding the applicability of the 2D+t method to planing boats in shallow water are studied.
