🚩 Diving Flag Alpha – Marine Safety Standard for Commercial and Recreational Divers | KFD
Stay Seen. Stay Safe.
The Diving Flag Alpha is a mandatory visual signal used to alert boats that divers are in the water. Whether you’re working offshore, conducting inshore inspections, or leading a recreational dive, displaying this flag is essential to protect your team and comply with international maritime safety requirements.
Built from high-visibility, heavy-duty material and mounted on a collapsible pole, the KFD Diving Flag Alpha is designed for real-world diving conditions. It’s lightweight, durable, and suitable for vessels of various sizes.
🔹 What Is the Alpha Diving Flag?
The Alpha Flag (white and blue swallowtail) signals to nearby vessels that a diver is below the surface and that vessels must keep clear and reduce speed. This is recognised under international maritime rules such as COLREGs Rule 27, especially for diving operations.
⚠️ Not to be confused with the red-and-white diver down flag commonly used in North America for recreational diving.
