A navigation line is a straight line extending towards an area of navigational interest and generally generated by two navigational aids or one navigational aid and a bearing.

Navigation lines and recommended tracks are mapped as ways (usually just two nodes) laying along the path where the objects are to be displayed. The way should carry the tags for correct rendering. Nodes belonging to other objects, such as leading lights, may be used. The following illustration shows two navigation lines and two recommended tracks. The latter carry seamark:recommended_track:orientation=... tags in order for the bearing to be displayed. The values are decimal numbers, representing the bearing in degrees true.
