The term "even keel" is a nautical term used to describe a ship's position in the water. When a ship is on an even keel, it means that the draft of the vessel is equal fore and aft. In simpler terms, the ship's keel is parallel to the waterline, which allows the vessel to float or proceed in a smooth and level manner. An even keel is an essential aspect of safe navigation for any vessel. If a ship is not on an even keel, it can lead to listing, which is when the ship leans to one side or the other due to uneven weight distribution.

Squat refers to the increase of a ship's draught as a result of its motion through water. It is a hydraulic phenomenon whereby the water displaced creates an increase in current velocity past the moving hull causing a reduction in pressure resulting in a localised reduction of the water level and, consequently, in a settling of the vessel deeper in the water. For various reasons-having to do with hull design, trim and other physical and operational factors-squat may be different at the fore and aft.

Surenfoncement du navire par petits fonds dû à la vitesse.

CONT

Le squat est l'augmentation du tirant d'eau d'un navire résultant du déplacement de celui-ci dans l'eau. Il s'agit d'un phénomène hydraulique par lequel l'eau déplacée crée une augmentation de la vitesse du courant le long de la coque en mouvement, causant ainsi une réduction de pression qui, à son tour, a pour effet de produire une baisse locale du niveau d'eau, permettant au navire de s'enfoncer plus profondément dans l'eau.
