Anyone responsible for a vessel at sea must be able to recognize other vessels and quickly interpret their situation and possible intentions, day and night. These flashcards illustrate night lights and day shapes that could commonly be encountered by sailors and professional mariners.

Learning the lights and shapes is a major part of a mariner’s study and this set of Nautical Flashcards makes a difficult yet important safety subject easy to master. Each card shows a vessel’s display of night time navigation lights (in color) or daytime shapes, as seen from your position. In the case of the cards showing lights the vessel’s silhouette is just discernible and the meaning is shown on the back. There are over 50 cards in the set, presented in a clear plastic hard case.
