(1) The arithmetic sum of the drafts forward and aft above and below the mean water-line. The angle of trim is the angle between the plane of flotation and the mean water-line plane. A vessel "trims by the head" or "trims by the stern" when the vessel inclines forward or aft so that her plane of flotation is not coincident with her mean water-line plane. See "Drag".
(1) Isambuku sezibalo zoyilo lwangaphambili ne-aft ngaphezulu nangaphantsi komphakathi wendawo athi amanzi kwinqanawe xhaxhe kuyo. I-engile yokulungeleleanisa umthwalo yi-engile ephakathi komgangatho wokujikeleza komphakathi wesityaba somgca wamanzi. Inqanawe ilungelelanisa ngentloko okanye ilungelelanisa ngesiqu senqanawe xa inqanawe ithoba okanye ukuze isichwelo sayo sokujikeleza asidibani nolungelelaniso lwayo lomgca wamanzi asutyaba. (2) Ukulungisa izikhephe ngeentsika ngokukhangela umoya.
