However, the angle between the lubber line and the keel line may be 2°, the keel being 2° E of the lubber line, and if the compass cannot be re-mounted to correct this, then the 2° must be algebraically added to the -17°, thus (1rW) + (+2°) = -17° + +2° = -15°.
Kunjalo jimbombo ephakathi komgca wesiseko senqanawa, wesiseko sebhashubhashu singayi 2° ibhashu-bhashu libeyi-2 °E somgca ukuba ikhampasi ayinokwenyuka kwakhona ukulungisa oku, kengoko i-2° mayibe yi-aljibra edityaniswe kwi-17°, ibeyi (lrw)+(+2°) =-17+2-=15
