The compass bearing obtained of X being 340º (C) and the Variation obtained from the chart being 24º·W, the Deviation is therefore 4º E when the vessel is heading 090º (C).
Isiphakamisi salatha mbombo esifumaneka kuX esingamakhulu amathathu anamashumi amane amanqanaba (C) kwakunye nokuguqu-guquka okufumaneka kwitshati okungamashumi amabini anane amanqanaba W, ukunxaxha ngoko ke sisine samanqanaba E xa inqanawa isiya kumashumi alithoba amanqanaba (C).
