are presented. The goal of this investigation is to improve the physical understanding of, as
well as assess the experimental and CFD capability for, deep-V planing hulls operating in
calm water and slamming when running in head waves (both regular and irregular). This
paper consists of two parts, which deal with the calm water and slamming in waves,
respectively. In Part I, simulations for trim, sinkage, and resistance in calm water are …
