If you’ve ever watched your flag shred itself in a coastal storm or tried to lash a flimsy cloth to a rolling deck, you know ordinary flags fail at sea.

That’s why we built the Union Jack Flag for Boat — a purpose-engineered flag system designed to handle everything Britain’s weather throws at you. From calm harbours to open water, from caravans to garden rails, it’s the only flag that truly goes anywhere your adventure takes you.
