First Repeater Flag – Nautical Signal Flag

The 1st Repeater, also known as the First Substitute, is part of the International Code of Signals. It allows the first flag in a hoist to be repeated without needing a second copy of that flag—an ingenious bit of traditional maritime communication. With its distinctive yellow and blue triangular design, the 1st Repeater is also a great-looking piece of authentic nautical décor. Hang it at the beach house, boat house, yacht club, marina—or give it to someone who appreciates the language and traditions of the sea.
