The Whale Warning Flag, 16" x 24"

The Whale Warning Flag was first introduced around Northern Vancouver Island by the North Island Marine Mammal Stewardship Association (NIMMSA) as a means of addressing the growing number of negative interactions between boats and humpback whales. By using the same flag design we are collectively promoting and strengthening a consistent message of good boating behavior around whales throughout the coastal waters of British Columbia, Canada and Washington State, USA.

• When you encounter whales within 0.65 miles (1km) of you raise the flag
