Ship squat for a theoretical hull model in trapezoidal variable cross-section canal

Abstract

This paper deals with ship squat phenomenon, which, in general, appears in shallow waters navigation, but with a more pronounced effect on canals passage. Therefore, theoretical calculations of ship squat have been made for a theoretical hull model of a general cargo ship, designed in Autoship, transiting a canal with various trapezoidal cross sections. The paper can be useful for ship designers, naval architects and naval officers, who have to know squat's effects, in order to prevent any shipping accidents.
