The PIANC report no.&nbsp; 121 “Harbour Approach Channels Design Guidelines” from 2014 lists a number of them that are advised to be&nbsp; used at design stage. The different formulae have a proven track record of fairly well predicting the magnitude&nbsp; of the squat of a ship sailing along the centreline of a (symmetric) channel with a typical trapezoidal cross&nbsp; section. Nevertheless, none of them considers the effect of asymmetry in the cross section and/or the fact that&nbsp; the ship does not sail along the centreline of a symmetrical cross section.</span><br><span lang=\"EN-US\" dir=\"ltr\">The present paper intends to give an overview of the most important squat parameters, including the effect of&nbsp; asymmetry.
