What should be done in the vicinity of the Alpha Flag?

The Alpha Flag, internationally recognized in maritime operations, signals that a vessel is currently engaged in underwater diving activities. Consequently, it is crucial for vessels in the area to respect this flag to ensure the safety of both divers and nearby vessels.

Keeping well clear at slow speed is the most appropriate action when in the vicinity of the Alpha Flag. By reducing speed and maintaining a safe distance, other craft can minimize the risk of accidents and avoid causing waves or wakes that could interfere with the divers' safety. This practice helps ensure that divers can operate without the worry of vessels encroaching on their area of work.

Maintaining high speed can lead to dangerous situations, as it may create dangerous wake conditions that jeopardize the divers' safety. Approaching with caution is somewhat prudent, but it does not adequately address the need for clear space from the divers. Ignoring the flag or continuing with operations puts both the divers and the vessel at risk, violating maritime safety protocols. Thus, the best practice is to keep well clear, at slow speed, when in the vicinity of the Alpha Flag.
