When is a chase boat required during a dive?

A chase boat is required when diving off a large platform or in open ocean primarily for safety and logistical reasons. In these scenarios, the distance from the shore or a support vessel increases the risks associated with diving, such as strong currents or the potential for diver separation from the dive team. A chase boat serves as an immediate response resource in case of emergencies, providing rapid assistance, additional safety measures, and a means of communication between divers and surface personnel.

In contrast, the other situations do not typically necessitate a chase boat. Recovery during compliance checks, for instance, does not require constant monitoring of divers in the water in the same way as open ocean dives. Similarly, shallow water dives and cold water dives may have different safety protocols or may be conducted in a more controlled environment where the risks are managed without the need for a chase boat. Thus, the requirement for a chase boat is most pertinent in the context of large platforms or expansive ocean settings where safety and emergency response are paramount.
