The aim of the invention is to provide a means of identifying the current position of a sail when sailing in darkness without having to use a light to see said sail. To this end, a device consisting of at least one bolt rope (11; 12; 13) or a profile strip (20) of a sail (10) or wind streamers (30) fixed to a sail is provided on the sails, said device being covered with a flexible reflective and/or luminescent material or provided with a material of that nature. |
