Signal Boats

Long ago sailors realized they needed to communicate with other boats that their voices could not reach. They invented flags with colors and patterns to speak commands or spell words as far as the eye can see.

Learn the international language of boats. Master the A-B-Cs of flags. Build boats each day, that use flags in their work: a fishing boat, a tug boat, a freighter, a rescue boat and more. Build a lighthouse whose flashing light speaks through storms.

Use your boats and flags to speak to friends far away.
