COMPANHIA DE NAVEGAÇÂO NORSUL S.A.

The flag has diagonal yellow and green quarters, with green occupying only part of the hoist and fly. A white circle bears a green N; the field divisions and circle are outlined in black. The funnel is white with a green top and a broad band of the flag, outlined black above and below. Rosanoski questions these unusual outlines, while noting that they help distinguish the colours.
