Many sea gulfs are not inferior to the seas in area and even surpass them. Mark with a "V" on the map the largest gulf, washing the western coast of Africa.

The task requires marking a specific location on the map with a "V". Since this is a static image and not an interactive map, I cannot perform this action directly. To answer this question, one would need to visually identify the largest gulf on the western coast of Africa on the provided map and mark it.
