What is handrailing in navigation?

Handrailing in navigation refers to the practice of following linear features on the terrain, such as rivers, roads, or ridgelines, to stay on course during navigation. This technique helps a navigator maintain orientation and make decisions based on prominent natural or man-made features that are familiar and recognizable.

By using linear features as guides, navigators can reduce the likelihood of becoming disoriented or lost. Handrailing allows for easier and more intuitive navigation, as these features often provide a clear path and can lead to the desired destination without the need for constant precise map reading or compass use.

Other options focus on different skills necessary for navigation, such as map reading and compass use, but they don't capture the specific method of handrailing. The emphasis on following linear features distinguishes this technique from merely using tools or understanding maps. Therefore, handrailing is a practical approach that enhances navigation by leveraging the geography of the area.
