When is it mandatory to have a chase boat during a dive?

A chase boat is essential during dives when there is a possibility for divers to become displaced because it enhances safety and provides immediate support. Displacement can occur due to various factors such as changing currents, equipment malfunctions, or sudden environmental conditions. Having a dedicated chase boat ensures that assistance is readily available should divers encounter difficulties, allowing for swift rescue and recovery actions.

While diving at night, in heavily trafficked waters, or in any conditions may warrant extra precaution, the primary reason for the mandatory presence of a chase boat focuses on the specific risk of displacement. This adds a crucial layer of security, especially in unpredictable environments where divers might stray from the intended dive path. Consequently, the necessity of the chase boat is fundamentally linked to the risks associated with diver safety and response readiness during their underwater excursions.
