If pyrotechnic visual distress signal are requiredhow many must be on board?

The U.S. Coast Guard requires recreational boats to carry at least three pyrotechnic visual distress signals (VDS) if they are operating on coastal waters, the Great Lakes, or any waters where they are more than three miles from shore. These signals must be approved by the Coast Guard and can include flares or other pyrotechnic devices. For inland waters, the regulations may vary, so it's essential to check local requirements. Always ensure that the signals are accessible and in good condition for emergencies.
