rettetningskolonne

A rettetningskolonne, which translates to "direction column" in English, is a term primarily used in maritime navigation and cartography. It refers to a column or section within nautical charts or navigational publications that provides information about the direction of currents, tides, or prevailing winds in a specific area. This information is crucial for sailors and mariners to plan their routes effectively, account for the drift caused by water or air movement, and ensure safe passage.

The data presented in a rettetningskolonne can vary depending on the chart or publication. It might include average current speeds and directions at different times of the day or tidal states, predominant wind directions and strengths, or even information on navigational hazards influenced by these forces. These columns are often accompanied by symbols or diagrams to visually represent the directional data. Mariners consult these columns to make informed decisions regarding their vessel's speed, course, and timing of departure or arrival, especially in areas with strong or variable currents and winds. The accurate representation of this data is vital for safe and efficient maritime operations.
