Third Repeater Flag – Nautical Signal Flag

The 3rd Repeater, also known as the Third Substitute, is part of the International Code of Signals. It is used to repeat the third flag in a signal hoist, allowing sailors to communicate repeated letters or signals without carrying duplicate sets of every flag aboard. With its bold, graphic design, the 3rd Repeater also makes a distinctive piece of authentic nautical décor—especially for anyone who appreciates the traditions and visual language of the sea.
