What Boaters Are Saying
About Flag in a Bag

The Story Behind Our Patented Tangle-Free Boat Flag System

Doug Jennings got tired of untangling his boat flag every time he left the dock, so he decided to invent a better one. When friends saw what he’d created, they wanted one, too. What started on a dock in Sarasota, FL, is now the only patented tangle-free boat flag system on the market, made in the USA.
