Abstract
    This paper addresses some aspects of shallow water theories used for the description of the flow around boats in the context  of confined navigation. We start by giving a brief account of the derivation of the most general version of the shallow water  system of equations for a boat with non‐constant beam and draught profiles. We will also consider the boat to be able to trim  and sinkage by hydrostatic effects. Then, we present a quick review of the two classical families of theories of the literature  on the matter: the energy and momentum approaches. We will comment their consistencies or inconsistencies with regards  to the aforementioned general model. Finally, some numerical results are presented on the general model and comparisons  with classical approaches such as the one proposed by Kreitner (1934), Schijf (1949) and Constantine (1960) will be shown.
