Note : The SHOM is the French national hydrographic office; it produces the nautical charts that aid safe navigation in French waters and certain areas of Africa, Antarctica, West Indies and the South-West Pacific.

Using charts safely involves keeping them up-to-date using Notices to Mariners
Mariners are requested to advise the French Hydrographic Authority at SHOM of the discovery of new or suspected dangers to navigation, or shortcomings in charts or publications
